Java Developer Tutorials

An Optional object in Java is a container object that can hold both empty and a non-null values. If an Optional object does contain a value, we say that it is present; if it does not contain a value, we say that it is empty. Here, we will take a look at the Optional class in Java and how it can be used to help improve your code. We will also look at some of the drawbacks of using the Optional keyword in Java and some best practices.

Jump to:

What is the Optional Type in Java?

Optional is a new type introduced in Java 8. It is used to represent a value that may or may not be present. In other words, an Optional object can either contain a non-null value (in which case it is considered present) or it can contain no value at all (in which case it is considered empty).

An Optional object can have one of the following possible states:

  • Present: The Optional object does not represent absence. A value is in the Optional object and it can be accessed by invoking the get() method.
  • Absent: The Optional object does represent the absence of a value; you cannot access its content with the get() method.

Why Do Developers Need Optional in Java?

Optional is generally used as a return type for methods that might not always have a result to return. For example, a method that looks up a user by ID might not find a match, in which case it would return an empty Optional object.

Optional can help reduce the number of null pointer exceptions in your code as well. It is not intended as a replacement for existing reference types, such as String or List, but, rather, as an addition to the Java type system.

How to Create an Optional Object in Java

There are several ways to create an Optional object in Java, including the static factory methods empty() and of(), which pertain to the Optional class. You can create an Optional object using the of() method, which will return an Optional object containing the given value if the value is non-null, or an empty Optional object if the value is null.

Programmers can also use the ofNullable() method, which will return an empty Optional object if the value is null, or an Optional object containing the given value if it is non-null. Finally, you can create an empty Optional object using the empty() method.

Once you have created an Optional object, you can use the isPresent() method to check if it contains a non-null value. If it does, you can use the get() method to retrieve the value. Developers can also use the getOrElse() method, which will return the value if it is present, or a default value if it is not.

Read: Introduction to Inner Classes in Java

The Java isPresent and ifPresent Methods

Developers can take advantage of the isPresent method to check if an Optional object is empty or non-empty. The ifPresent method, meanwhile, can check if a particular Optional object is non-empty. The following code example illustrates how you can work with the ifPresent and isPresent methods in Java:

import java.util.Optional;
   public class OptionalDemo {  
      public static void main(String[] args) {
         Optional obj1 = Optional.of
         ("This is a sample text"); 
         Optional obj2 = Optional.empty();
         if (obj1.isPresent()) {          
            System.out.println
            ("isPresent method called on obj1 returned true");
         }       
    obj1.ifPresent(s -> System.out.println
   ("ifPresent method called on obj1"));
    obj2.ifPresent(s -> System.out.println
    ("ifPresent method called on obj2 "));
   }
}

In the above code example, we first check to see if two Optional object exists, using the isPresent() method. We assigned a value to obj1, so it will print out the string “This is a sample text”. obj2, however, was assigned an empty value, so it will print out nothing. We then print some more text to alert us that ifPresent was called on both of our Optional objects.

How to use Optional Objects in Java

There are a number of ways to create Optional objects. The most common way is to use the static factory method Optional.of(T), which creates an Optional object that is present and contains the given non-null value, as shown in the code snippet below:

Optional optional = Optional.of("value");

Additionally, we can create an empty Optional object using the static factory method Optional.empty, as shown in the code example below:

Optional optional = Optional.empty();

If we have a value that might be null, we can use the static factory method Optional.ofNullable(T) to create an Optional object that may or may not be present:

Optional optional = Optional.ofNullable(null);

Programmers can also use methods like ifPresent() and orElse() if you need to perform some action based on whether the optional has been set (if it contains a certain value) or if not, respectively:

Optional optionalString = Optional.of("value");
optionalString.ifPresent(s -> System.out.println(s));

Pros and Cons of using Optional Objects in Java

There are a few key pros to using Optional that Java developers should be aware of, including:

  • Optional can help to prevent NullPointerException errors by making it explicit when a variable may or may not contain a value. This can lead to cleaner and more readable code.
  • Optional provides several methods that can be used to safely work with data that may or may not be present.
  • Optional can be used as an ordinary class, which means that there is no need for special syntax for invoking methods or accessing fields.

Despite these benefits, there are a few potential downsides to using Optional as well:

  • Optional can add significant overhead to code execution time, as the Optional wrapper must be created and checked each time a variable is accessed.
  • Some developers find Optional confusing and difficult to work with, which can lead to more errors instead of fewer, and more development time and effort than usual as a result.

Alternatives to Using Optional Objects in Java

There are a few alternatives to using Optional, such as using the null check operator (?.), using an if-else statement, or using a ternary operator.

The null check operator can be used to check if a value is null before accessing it. This can be done by using the ?. operator before the variable name. For example, the following Java code will check if the variable abc is null before accessing it:

if (abc != null) {
//Write your code here
}

If the variable abc is not null, the code inside the if statement will be executed. The if-else statement in the above code checks if the value is null before accessing it.

Best Practices for Using Optional

Below are some best practices to consider when using Optional in your Java code:

  • Use Optional to lower the amount of null pointer exceptions and account for times when returned values are empty or missing.
  • Do not use Optional as a stop-all for every type of null pointers. Coders still need to account method and constructor parameters that may also contain empty values.
  • Consider the context of your Optional objects; absent Optional values can mean different things, such as a particular value not being found versus no value at all being found. Account for these possibilities.
  • Use Optional as a return type and then retrieve its value if it is present or provide a different outcome if not.
  • Do not use Optional a parameter for methods or constructors. Using it in such  manner results in sloppy, hard to read, and difficult to maintain code.

Final Thoughts on Using Optional Objects in Java

Optional is a new feature in Java 8 that provides a way to handle null values in a more elegant way. The java.util.Optional class was introduced in Java 8 as a way to address the common problem of null pointer exceptions. By using Optional, programmers can avoid NullPointerExceptions and write cleaner code.

JAD software development

The Joint Application Development methodology is a software development approach that aims to bring stakeholders, developers, and users together in joint sessions. These joint sessions are workshops where project requirements and design are defined. We take a look at the JAD methodology in great detail, exploring its advantages and disadvantages, best practices, and the role it plays in software creation.

Jump to:

What is Joint Application Design (JAD)?

JAD (an acronym for Joint Application Design) is a methodology used in software development to gather and define software requirements rapidly. Its purpose is to bring all stakeholders in the design process to a common consensus as far as the requirements for the project is concerned and to foster effective and efficient communication between all those involved.

JAD was created by IBM in the late 1970s as a technique for quicker development timeframes and better client satisfaction when compared to more traditional practices, such as Waterfall. A main tenant of this approach is involving the customer from the beginning of the software development life cycle (SDLC) and keeping them engaged until product release.

The JAD methodology is most effective when used for well-defined problems where all stakeholders can participate, and when there is a skilled and experienced facilitator to guide the process.

What are the Different Phases of JAD?

The JAD methodology typically involves the following phases:

  • Preparation: The project sponsor, stakeholders, and facilitator are identified and a JAD session is scheduled. The agenda and objectives of the session are defined, and the participants are invited and prepared.
  • Session: The JAD session is a structured workshop in which the experts participate in interactive discussions and decision-making activities to define the requirements and design for the software application.
  • Documentation: The outcome of the JAD session is documented, including detailed notes, sketches, and other materials generated during the session. The documentation is used to create a final specification for the software application.
  • Implementation: The software development team uses the specification created during the JAD session to build the application. Regular meetings between the stakeholders and developers are held to ensure that the implementation meets their expectations.

What is a JAD Session?

As noted, a JAD session is a structured workshop that brings together project managers, stakeholders, developers, and experts to define and refine the requirements for a software application. In particular, a JAD session has the following characteristics:

  • A JAD session typically lasts one to three days, and is facilitated by a JAD facilitator who is knowledgeable about the software development process and can manage the session effectively.
  • JAD sessions should have a clear agenda and defined objectives. You should ensure that the key persons representing the technical and business worlds are available during these meetings.
  • Questions and agenda items are what get people talking during meetings. Therefore, we should not expect quick resolutions from them. To ensure the team is on the same page, ask pertinent questions, make notes, and delegate tasks.
  • JAD sessions aim to promote innovative ideas and productive dialogue among employees from different departments. Team members should provide input to one another as they work through problems.
  • Scheduled JAD sessions, also known as JAD workshops, must be held if the teams cannot reach a consensus. Most JAD meetings occur during the project’s early stages of development.
  • During the session, participants engage in interactive discussions, decision-making activities, and brainstorming exercises to define and refine the requirements and design for the software application.
  • The outcome of the JAD session is a detailed document that will be used to create the final specification for the project, including notes, sketches, and other materials generated during the session.
  • JAD sessions can be effective in situations where there is a clear, well-defined problem to be solved and where all stakeholders can participate in the session. The success of a JAD session depends on the preparation, participation, and facilitation by all involved parties.

Read: Project Management Software and Tools for Developers

Who Is Involved in a JAD Session?

In a typical JAD process, there are several key stakeholders involved, including:

  • Project sponsor: The person or organization that is responsible for the project and who has the authority to make decisions and allocate resources.
  • Facilitator: The JAD facilitator is responsible for ensuring that the session runs smoothly, that all participants have a chance to contribute, and that the outcome is documented and used to create a final specification for the software application.
  • Subject Matter Experts: Subject matter experts are individuals who have expertise in specific areas related to the project, such as the business processes, technology, or legal requirements.
  • End-users: End-users are the individuals who will use the system or product being developed. They provide their input during the JAD sessions to ensure that the system meets their needs and is user-friendly.
  • Developers: The software development team who will be responsible for building the application based on the requirements and design defined in the JAD session.
  • Observers: It is the responsibility of a JAD observer to observe each JAD session and to gather knowledge regarding end-user needs, assessing JAD session decisions, and interacting with JAD participants outside of the scheduled JAD sessions.

How to Conduct a JAD Session

Conducting a successful Joint Application Design session requires careful preparation, facilitation, and follow-up. To conduct a JAD session, follow these steps:

  • Identify the project requirements and determine the scope of the JAD session.
  • Select the stakeholders participating in the JAD session and invite them to attend.
  • Ascertain that all participants are available at the time scheduled for the JAD meeting.
  • Provide all participants with pre-session materials, such as project documents, requirements documents, and other relevant information.
  • Review the agenda of the session and introduce the facilitator at the beginning.
  • Identify and document the requirements using collaborative techniques, such as brainstorming, group discussions, and visual aids.
  • Ensure the requirements are accurate and complete throughout the session by continuously reviewing and refining them.
  • Summarize the session’s results and ensure all participants agree on the requirements.
  • After the session, document the results and distribute them to all stakeholders for review and feedback.

Benefits of JAD

Below is a list of some the benefits that JAD software development offers both programmers and project managers:

  • Improved Requirements Gathering: JAD sessions bring together stakeholders, developers, and experts to define and refine the requirements for a software application.
  • Increased Collaboration: JAD sessions encourage collaboration between stakeholders, developers, and experts throughout the project life cycle.
  • Reduced Misunderstandings: JAD sessions provide an opportunity to clarify requirements and design decisions, which helps to reduce misunderstandings and the need for rework.
  • Accelerated Development Cycles: JAD sessions are designed to be fast-paced and focused, and can help to accelerate the software development cycle by reducing the time spent on requirements gathering and design.
  • Improved Communication: JAD sessions provide a forum for stakeholders, developers, and experts to communicate and exchange ideas, which can help you build trust and improve the overall quality of your application.
  • Better Documentation: The outcome of a JAD session is documented in detail, which provides a complete and accurate specification for the software application.

To help foster better communication and collaboration among your team, we compiled a list of the top collaboration software for developers.

Disadvantages of JAD

Despite its advantages, JAD also has some disadvantages worth mentioning, including:

  • Resource Intensive: JAD sessions can be resource intensive, both in terms of time and personnel, as they require the participation of multiple stakeholders, developers, and experts. Short-staffed or time-constrained organizations may find this challenging.
  • Limited Participation: JAD sessions are most effective when all stakeholders can participate, but this is not always possible. If some stakeholders are unable to participate, the outcome of the JAD session may be limited, and there may be a risk of misunderstandings or errors in the requirements and design.
  • Dependence on the Facilitator: The success of a JAD session depends largely on the quality of the facilitator, and a poor facilitator can undermine the effectiveness of the session.
  • Potential for Groupthink: JAD sessions can be vulnerable to groupthink, where participants are more concerned with reaching a consensus than with exploring different perspectives and solutions.
  • Potential for Conflict: JAD sessions can also lead to conflict, particularly when there are different opinions and perspectives among stakeholders. This can be a challenge for the facilitator to manage and can undermine the effectiveness of the session if not handled properly.
  • Dependence on Face-to-Face Interaction: JAD sessions are designed to be face-to-face, but this is not always possible, particularly in a remote or distributed environment. This is a challenge that can limit the effectiveness of the JAD approach.

Best Practices for Conducting JAD Sessions

In order to get the most out of your JAD sessions, we recommend following the best practices below:

  • Invite Relevant People: JAD sessions ideally have 10 or fewer participants. Of those, you should always have a facilitator, key executive, end-user representative, developer, note-taker, and relevant specialists.
  • Set Clear Goals: Each session you conduct should have clearly defined goals and outcomes. Define what you will discuss and any deliverables that will be expected.
  • Conduct Meetings Offsite: To ensure meeting participants can focus and are not pulled away for other tasks, conduct meetings outside of the workplace.
  • Limit sessions: You should hold no more than 10 JAD sessions or workshops to ensure the project gets defined in a reasonable time period.
  • Use Appropriate Tools: During sessions you will want to make certain members have access to the necessary tools, which can include project management software, prototyping tools, and flowcharts.
  • Create Deliverables: At the end of your sessions, the facilitator should walk away with a clear project definition, system prototypes, user-interface designs, timeframe estimates, budget and resource needs, and any database schema the program will require.
  • Final Approvals: At the end of your JAD sessions you will need to obtain approval from the key executive, as well as the end-user representative.

JAD Tools and Software

There are many tools that can be useful for a project manager using a JAD approach. Some tools will foster communication and collaboration, while others can be useful for design documents, project planning, and resource allocation. Below are several types of tools you can use when conducting JAD sessions:

  • Project Management: PM tools help project managers plan and track project progress and manage tasks.
  • Communication and Collaboration: Collaboration tools help teams work together and communicate on common tasks. Developers also have collaboration software that lets them work on code and share code changes in real-time.
  • Flowchart and Diagramming: Flowchart software helps teams and programmers design, plan, and layout the structure of an application. This can include user interfaces, workflows, input/output processes, and any functionality the program should have.
  • Critical Path Analysis: CPA tools are used to visualize project timelines and dependencies. They allow project managers to identify critical tasks, allocate resources more effectively, and reduce project delays.
  • SWOT Analysis: SWOT Analysis frameworks help teams identify strengths, weaknesses, opportunities, and threats in an organization and project.
  • Pareto Charts: Pareto charts help project managers identify mission critical issues that will have the highest impact on the development process.

Microsoft Project Tips and Tricks https://www.developer.com/project-management/microsoft-project-tips/ Fri, 08 Dec 2023 12:43:48 +0000 https://www.developer.com/?p=60297 Microsoft Project is a powerful project management tool. Learn the best tips and tricks to get the most out of Microsoft Project.

The post Microsoft Project Tips and Tricks appeared first on Developer.com.

Microsoft Project is a popular tool for project managers and developers looking to keep their software projects on track and to stay organized. In this guide, we provide some tips and tricks that can help you maximize your productivity and user experience when using the popular project management software.

Top Tips for Microsoft Project

Below are some of the best tips and tricks to get the most out of Microsoft Project:

Create A Manual List Of Tasks in MS Project

You should have a detailed list of project tasks handy before using MS Project in order to avoid a scheduling mess caused by forgotten tasks that you must insert in the middle of a project.

While it can be tough to list every task that must be completed for a project, this essential step can save you headaches later on. To make it easier, try starting with a list of higher-level tasks and breaking them into smaller subtasks. Once ready, you can enter the tasks into Microsoft Project and let it complete the scheduling calculations for you.

When making your list of tasks, focus on their overall structure and how they relate. Avoid worrying about their dates or durations, as MS Project can do those calculations automatically as long as the task relationships are correctly defined. In fact, many suggest not inputting any task dates or durations into Microsoft Project when starting, as it can only complicate things.

Microsoft Project Tasks

Create A Work Breakdown Structure for Project Schedules

Project managers can simplify the tedious task of coming up with a project schedule by first creating a work breakdown structure (WBS). Doing so can help you break down complex work into manageable tasks and more accurately estimate how much time it will take to complete those tasks. The WBS can also help project managers set task dependencies and determine what roles are needed to complete each task.

To create a work breakdown structure in Microsoft Project, do the following:

  1. Navigate to Project Service.
  2. Select the Projects option.
  3. Click on your desired project.
  4. Navigate to the bar that sits at the top of the screen.
  5. Click on the down arrow next to the project’s name.
  6. Click on Work Breakdown Structure or WBS.
  7. Click Add Task.
  8. Add the task by filling in all necessary fields.
  9. Click Save.
  10. Keep adding tasks until your WBS is finished.

As you create your WBS, you can indent and outdent tasks to move them under one another or out to a different level to create a desired hierarchy.

Microsoft Projects Tips

Switch To Auto-Scheduled Tasks in Microsoft Project

Users can avoid potential scheduling problems in Microsoft Project by making one minor tweak to the settings. Since the PM software manually schedules tasks by default (you define the start/end date and duration) and does not calculate task dates automatically when a change is made to a predecessor, you will need to make the switch on your own.

There may be occasions when you want tasks to be manually scheduled, but if you are beginning with Microsoft Project, your best bet is to ensure new tasks are auto-scheduled to avoid conflicts down the line. In doing so, you can leverage the power of the software to schedule tasks based on calendars, constraints, dependencies, and so forth.

To avoid problems from the Manually Scheduled default task mode in MS Project, do the following to change all new tasks to Automatically Scheduled:

  1. Go to the Task tab.
  2. Navigate to the Schedule group and click on Task Mode.
  3. Click on Auto Schedule.

Set A Baseline for Your Projects

Most projects do not go precisely as planned. That is why project managers need a baseline, as it gives them something to compare progress or the actual state of a project to. You can set up to 11 baselines in Microsoft Project to see if you are headed in the right direction. The software gives you the option to set baselines for specific tasks or entire projects.

Once your project’s tasks and dates are set, do the following to set a baseline:

  1. Navigate to the Project tab.
  2. Go to the Schedule group.
  3. Click on Set Baseline.
  4. Click on Set Baseline again in the dropdown menu.
  5. Once the Set Baseline window appears, you can select your baseline.

When setting your baseline, make sure that your Baseline Start and Baseline Finish columns have been added. From there:

  1. Right-click on your chart.
  2. Select Show/Hide Bar Styles.
  3. Select Baseline.
  4. Select the baseline you just set.

Gray bars that represent your baseline should appear and can be used to view any deviations.

Choose The Right View for Your Project Needs

Microsoft Project puts several views at project managers’ disposal so they can gain instant insight into their software development team’s progress and make necessary adjustments on the fly to optimize workflows. Since these views offer different insights and cater to varying needs, you will have to make sure you pick the right ones for optimal efficiency.

Here is a breakdown of what some of the views in Microsoft Project have to offer that should make them easier to sift through, including Calendar View, Timeline View, Network Diagram View, and Gantt Chart View.

Calendar View in MS Project

Microsoft Project’s Calendar View breaks down a project into sections according to dates. Use it to see what needs to be completed and when.

Microsoft Project views

Timeline View in Microsoft Project

True to its name, Microsoft Project’s Timeline View arranges tasks on a timeline so project managers can see where a project stands and pinpoint any scheduling conflicts. The Timeline View lets you insert notes and milestones to individual tasks, and you can edit it manually via drag-and-drop, adding colors, and so on.

Microsoft Project

Network Diagram View

If you prefer to analyze data graphically, use the Network Diagram View. It offers a graphical representation of projects and task dependencies, allowing you to see potential spots where changes may be critical. The Network Diagram View uses boxes or nodes to represent tasks. Each is connected by an arc or line to show how one task must be completed before another can start. If you need to see task dependencies and critical paths so you can allocate resources accordingly to meet deadlines, the Network Diagram View is right for you.

Microsoft Project tricks

Gantt Chart View in MS Project

The Gantt Chart View in Microsoft Project provides a quick project overview. It breaks down tasks into specific phases and puts them on a timeline with start and end dates. Project managers in charge of complex projects can use the Gantt Chart View to track projects, pinpoint potential delays, and quickly adjust allocated resources. To get further insight into your project’s progress, Microsoft Project lets you filter Gantt chart data by resource, status, duration, etc. And you can customize your Gantt chart via color coding to make it easier to differentiate between different tasks.

Explore the different types of databases, how to connect to them, and how to query them.

The post Python Database Basics appeared first on Developer.com.

Databases are an important part of most modern software development. They serve as a repository for storing, organizing, manipulating, and retrieving data and information. Python, being a versatile programming language, offers several modules and libraries for working with databases. We will explore the fundamentals of database programming in Python, with a focus on using the SQLite database system, which is lightweight, easy to use, and part of the Python standard library.

Jump to:

Introduction to SQLite

SQLite tutorial

Databases can be thought of as a structured collection of data that is organized in such a manner that applications can quickly select and retrieve specific pieces of information that are often related to one another (but not always). Databases are necessary for storing and managing data in applications, including small scripts and even large-scale, data-driven web applications.

SQLite is a C library that functions as a disk-based database. Unlike most other database management systems (DBMS), SQLite does not require a separate server process. In addition, SQLite provides access to the database using a nonstandard variant of the structured query language (SQL). It is a great option for embedded systems, testing, and small to medium-sized applications.

SQLite is a perfect database to start with for beginners due to its simplicity, easy configuration, and minimal setup requirements. It is a Serverless database, which means developers do not need to set up a separate server to use it. In addition, SQLite databases are stored in a single file; this makes them easy to share and move between different systems. Below, we walk through the basics of working with SQLite using Python, opening doors for more advanced database concepts down the line.

How to Set Up the Dev Environment

Before we begin, we have to first make certain that Python is installed on your computer. To do so, open a terminal or command prompt and type:

python --version

If Python is not installed, you will need to download and install it from the official Python website. You can also learn how to install Python in our tutorial: How to Install Python.

Installing SQLite

Python comes with the sqlite3 module, which provides an interface to the SQLite database. Programmers do not need to install anything extra to work with SQLite in Python.

Connecting to a Database

As stated, the sqlite3 module is part of the Python standard library and provides a powerful set of tools for working with SQLite databases. Before we can use it, we must import the module into our Python scripts. We can do so in the following manner:

import sqlite3

Establishing a Database Connection in Python

In order to interact with an SQLite database, programmers need to first establish a database connection. This can be achieved using the connect function contained in the sqlite3 module. Note that if the noted database file does not exist, SQLite will create it.

# Connect to the named database (or, if it does not exist, create one)

conn = sqlite3.connect('sample.db')

Creating a Cursor in SQLite

In order to execute database queries and retrieve results in an SQLite database, you must first create a cursor object. This process occurs after you create your connection object.

# How to create a cursor object in order to execute SQL queries

cursor = conn.cursor()

Creating a Table

In relational database management systems (RDBMS), data is organized into tables, each of which is made up of rows (horizontal) and columns (vertical). A table represents a specific concept, and columns define the attributes of that concept. For instance, a database might hold information about vehicles. The columns within that table might be labeled make, type, year, and model. The rows, meanwhile, would hold data points that aligned with each of those columns. For instance, Lincoln, car, 2023, Nautilus.

Read: PyCharm IDE Review

How to Structure Data with SQL

SQL is the standard language for operating within relational databases. SQL provides commands for data and database manipulation that include creating, retrieving, updating, and deleting data. To create a table, database developers use the CREATE TABLE statement.

Below, we create a simple table to store information about students, including their student_id, full_name, and age:

# Create a table

cursor.execute('''

    CREATE TABLE IF NOT EXISTS students (

        student_id INTEGER PRIMARY KEY,

        full_name TEXT NOT NULL,

        age INTEGER NOT NULL

    )

''')

# Commit our changes

conn.commit()

In the above code snippet, CREATE TABLE defines the table name, column names, and their respective data types. The PRIMARY KEY of the student_id column is used to ensure that each id value is unique, as primary values must always be unique.

If we wish to add data to a table, we can use the INSERT INTO statement. This statement lets developers specify which table and column(s) to insert data into.

Inserting Data into a Table

Below is an example of how to insert data into an SQLite database with the SQL command INSERT INTO:

# Insert data into our table

cursor.execute("INSERT INTO students (full_name, age) VALUES (?, ?)", ('Ron Doe', 49))

cursor.execute("INSERT INTO students (full_name, age) VALUES (?, ?)", ('Dana Doe', 49))

# Commit changes

conn.commit()

In this code example, we used parameterized queries to insert data into our students table. The values are tuples, which helps prevent SQL injection attacks, improves code readability, and is considered a best practice.

How to Query Data in SQLite

The SQL SELECT statement is used when we want to query data from a given table. It allows programmers to specify which columns they want to retrieve, filter rows (based on criteria), and sort any results.

How to Execute Database Queries in Python

To execute a query in Python, you can use the execute method on a cursor object, as shown in the example SQL statement:

# How to query data

cursor.execute("SELECT * FROM students")

rows = cursor.fetchall()

The fetchall method in the code above retrieves every row from the last query that was executed. Once retrieved — or fetched — we can then iterate over our query results and display the data:

# Display the results of our query

for row in rows:

    print(row)

Here, we print the data stored in the students table. We can customize the SELECT statement to retrieve specific columns if we want, or filter results based on conditions and criteria as well.

Updating and Deleting Data in SQLite

There are times when we will want to update existing records. On those occasions, we will use the UPDATE statement. If we want to delete records, we would use the DELETE FROM statement instead. To begin, we will update the age of our student with the name ‘Ron Doe’:

# Updating our data

cursor.execute("UPDATE students SET age=? WHERE name=?", (50, 'Ron Doe'))

# Commit our changes

conn.commit()

In this code, we updated Ron Doe’s age from 49 to 50.

But what if we wanted to delete a record? In the below example, we will delete the record for the student named Dana Doe:

# Deleting a record

cursor.execute("DELETE FROM students WHERE name=?", ('Dana Doe',))

# Commit our changes

conn.commit()

Best Practices for Working With Databases in Python

Below we highlight some best practices and tips for working with databases in Python, including:

  • Use parameterized queries
  • Use exception handling
  • Close database connections

Use Parameterized Queries

Developers and database administrators should always use parameterized queries in order to prevent SQL injection attacks. Parameterized queries are more secure because they separate SQL code from data, reducing the risk of malicious actors. Here is an example of how to use parameterized queries:

# How to use parameterized queries

cursor.execute("INSERT INTO students (full_name, age) VALUES (?, ?)", ('Ron Die', 49))

Use Exception Handling

Programmers should always encase database operations in try-except blocks to handle possible errors gracefully. Some common exceptions include sqlite3.OperationalError and sqlite3.IntegrityError.

try:

    # Database operation example

except sqlite3.Error as e:

    print(f" The SQLite error reads: {e}")

Close Database Connections

Best database practices call for developers to always close database connections and cursors when you are finished working with databases. This makes sure that resources are released and pending changes are committed.

# How to close the cursor and database connection

cursor.close()

conn.close()

Final Thoughts on Python Database Basics

In this database programming and Python tutorial, we covered the basics of working with databases in Python using SQLite. We learned how to connect to a database, create tables, and insert, query, update, and delete data. We also discussed best practices for working with databases, which included using parameterized queries, handling exceptions, and closing database connections.

Multithreading is a powerful concept in Java, allowing programs to execute multiple threads concurrently. However, this ability places the onus of managing synchronization, ensuring that threads do not interfere with each other and produce unexpected results, on the developer. Thread synchronization errors can be elusive and challenging to detect, making them a common source of bugs in multithreaded Java applications. This tutorial describes the various types of thread synchronization errors and offer suggestions for fixing them.

Jump to:

Race Conditions

A race condition occurs when the behavior of a program depends on the relative timing of events, such as the order in which threads are scheduled to run. This can lead to unpredictable results and data corruption. Consider the following example:

public class RaceConditionExample {

    private static int counter = 0;


    public static void main(String[] args) {

        Runnable incrementTask = () -> {

            for (int i = 0; i < 10000; i++) {

                counter++;

            }

        };

        Thread thread1 = new Thread(incrementTask);

        Thread thread2 = new Thread(incrementTask);

        thread1.start();

        thread2.start();

        try {

            thread1.join();

            thread2.join();

        } catch (InterruptedException e) {

            e.printStackTrace();

        }

        System.out.println("Counter: " + counter);

    }

}

In this example, two threads are incrementing a shared counter variable. Due to the lack of synchronization, a race condition occurs, and the final value of the counter is unpredictable. To fix this, we can use the synchronized keyword:

public class FixedRaceConditionExample {

    private static int counter = 0;

    public static synchronized void increment() {

        for (int i = 0; i < 10000; i++) {

            counter++;

        }

    }

    public static void main(String[] args) {

        Thread thread1 = new Thread(FixedRaceConditionExample::increment);

        Thread thread2 = new Thread(FixedRaceConditionExample::increment);

        thread1.start();

        thread2.start();

        try {

            thread1.join();

            thread2.join();

        } catch (InterruptedException e) {

            e.printStackTrace();

        }

        System.out.println("Counter: " + counter);

    }

}

Using the synchronized keyword on the increment method ensures that only one thread can execute it at a time, thus preventing the race condition.

Detecting race conditions requires careful analysis of your code and understanding the interactions between threads. Always use synchronization mechanisms, such as synchronized methods or blocks, to protect shared resources and avoid race conditions.

Deadlocks

Deadlocks occur when two or more threads are blocked forever, each waiting for the other to release a lock. This situation can bring your application to a standstill. Let’s consider a classic example of a deadlock:

public class DeadlockExample {

    private static final Object lock1 = new Object();

    private static final Object lock2 = new Object();

    public static void main(String[] args) {

        Thread thread1 = new Thread(() -> {

            synchronized (lock1) {

                System.out.println("Thread 1: Holding lock 1");

                try {

                    Thread.sleep(100);

                } catch (InterruptedException e) {

                    e.printStackTrace();

                }

                System.out.println("Thread 1: Waiting for lock 2");

                synchronized (lock2) {

                    System.out.println("Thread 1: Holding lock 1 and lock 2");

                }

            }

        });

        Thread thread2 = new Thread(() -> {

            synchronized (lock2) {

                System.out.println("Thread 2: Holding lock 2");

                try {

                    Thread.sleep(100);

                } catch (InterruptedException e) {

                    e.printStackTrace();

                }

                System.out.println("Thread 2: Waiting for lock 1");

                synchronized (lock1) {

                    System.out.println("Thread 2: Holding lock 2 and lock 1");

                }

            }

        });

        thread1.start();

        thread2.start();

    }

}

In this example, Thread 1 holds lock1 and waits for lock2, while Thread 2 holds lock2 and waits for lock1. This results in a deadlock, as neither thread can proceed.

To avoid deadlocks, ensure that threads always acquire locks in the same order. If multiple locks are needed, use a consistent order to acquire them. Here’s a modified version of the previous example that avoids the deadlock:

public class FixedDeadlockExample {

    private static final Object lock1 = new Object();

    private static final Object lock2 = new Object();

    public static void main(String[] args) {

        Thread thread1 = new Thread(() -> {

            synchronized (lock1) {

                System.out.println("Thread 1: Holding lock 1");

                try {

                    Thread.sleep(100);

                } catch (InterruptedException e) {

                    e.printStackTrace();

                }

                System.out.println("Thread 1: Waiting for lock 2");

                synchronized (lock2) {

                    System.out.println("Thread 1: Holding lock 2");

                }

            }

        });

        Thread thread2 = new Thread(() -> {

            synchronized (lock1) {

                System.out.println("Thread 2: Holding lock 1");

                try {

                    Thread.sleep(100);

                } catch (InterruptedException e) {

                    e.printStackTrace();

                }

                System.out.println("Thread 2: Waiting for lock 2");

                synchronized (lock2) {

                    System.out.println("Thread 2: Holding lock 2");

                }

            }

        });

        thread1.start();

        thread2.start();

    }

}

In this fixed version, both threads acquire locks in the same order: first lock1, then lock2. This eliminates the possibility of a deadlock.

Preventing deadlocks involves careful design of your locking strategy. Always acquire locks in a consistent order to avoid circular dependencies between threads. Use tools like thread dumps and profilers to identify and resolve deadlock issues in your Java programs. Also, consider reading our tutorial on How to Prevent Thread Deadlocks in Java for even more strategies.

Starvation

Starvation occurs when a thread is unable to gain regular access to shared resources and is unable to make progress. This can happen when a thread with a lower priority is constantly preempted by threads with higher priorities. Consider the following code example:

public class StarvationExample {

    private static final Object lock = new Object();

    public static void main(String[] args) {

        Thread highPriorityThread = new Thread(() -> {

            while (true) {

                synchronized (lock) {

                    System.out.println("High Priority Thread is working");

                }

            }

        });

        Thread lowPriorityThread = new Thread(() -> {

            while (true) {

                synchronized (lock) {

                    System.out.println("Low Priority Thread is working");

                }

            }

        });

        highPriorityThread.setPriority(Thread.MAX_PRIORITY);

        lowPriorityThread.setPriority(Thread.MIN_PRIORITY);

        highPriorityThread.start();

        lowPriorityThread.start();

    }

}

In this example, we have a high-priority thread and a low-priority thread both contending for a lock. The high-priority thread dominates, and the low-priority thread experiences starvation.

To mitigate starvation, you can use fair locks or adjust thread priorities. Here’s an updated version using a ReentrantLock with the fairness flag enabled:

import java.util.concurrent.locks.Lock;

import java.util.concurrent.locks.ReentrantLock;


public class FixedStarvationExample {

    // The true boolean value enables fairness

    private static final Lock lock = new ReentrantLock(true);

    public static void main(String[] args) {

        Thread highPriorityThread = new Thread(() -> {

            while (true) {

                lock.lock();

                try {

                    System.out.println("High Priority Thread is working");

                } finally {

                    lock.unlock();

                }

            }

        });

        Thread lowPriorityThread = new Thread(() -> {

            while (true) {

                lock.lock();

                try {

                    System.out.println("Low Priority Thread is working");

                } finally {

                    lock.unlock();

                }

            }

        });

        highPriorityThread.setPriority(Thread.MAX_PRIORITY);

        lowPriorityThread.setPriority(Thread.MIN_PRIORITY);

        highPriorityThread.start();

        lowPriorityThread.start();

    }

}

The ReentrantLock with fairness ensures that the longest-waiting thread gets the lock, reducing the likelihood of starvation.

Mitigating starvation involves carefully considering thread priorities, using fair locks, and ensuring that all threads have equitable access to shared resources. Regularly review and adjust your thread priorities based on the requirements of your application.

Check out our tutorial on the Best Threading Practices for Java Applications.

Data Inconsistency

Data inconsistency occurs when multiple threads access shared data without proper synchronization, leading to unexpected and incorrect results. Consider the following example:

public class DataInconsistencyExample {

    private static int sharedValue = 0;

    public static void main(String[] args) {

        Runnable incrementTask = () -> {

            for (int i = 0; i < 1000; i++) {

                sharedValue++;

            }

        };

        Thread thread1 = new Thread(incrementTask);

        Thread thread2 = new Thread(incrementTask);

        thread1.start();

        thread2.start();

        try {

            thread1.join();

            thread2.join();

        } catch (InterruptedException e) {

            e.printStackTrace();

        }

        System.out.println("Shared Value: " + sharedValue);

    }

}

In this example, two threads are incrementing a shared value without synchronization. As a result, the final value of the shared value is unpredictable and inconsistent.

To fix data inconsistency issues, you can use the synchronized keyword or other synchronization mechanisms:

public class FixedDataInconsistencyExample {

    private static int sharedValue = 0;


    public static synchronized void increment() {

        for (int i = 0; i < 1000; i++) {

            sharedValue++;

        }

    }

    public static void main(String[] args) {

        Thread thread1 = new Thread(FixedDataInconsistencyExample::increment);

        Thread thread2 = new Thread(FixedDataInconsistencyExample::increment);

        thread1.start();

        thread2.start();

        try {

            thread1.join();

            thread2.join();

        } catch (InterruptedException e) {

            e.printStackTrace();

        }
        System.out.println("Shared Value: " + sharedValue);

    }

}

Using the synchronized keyword on the increment method ensures that only one thread can execute it at a time, preventing data inconsistency.

To avoid data inconsistency, always synchronize access to shared data. Use the synchronized keyword or other synchronization mechanisms to protect critical sections of code. Regularly review your code for potential data inconsistency issues, especially in multithreaded environments.

Java Programming tutorials

Java, as a versatile and widely-used programming language, provides support for multithreading, allowing developers to create concurrent applications that can execute multiple tasks simultaneously. However, with the benefits of concurrency come challenges, and one of the critical aspects to consider is memory consistency in Java threads.

In a multithreaded environment, multiple threads share the same memory space, leading to potential issues related to data visibility and consistency. Memory consistency refers to the order and visibility of memory operations across multiple threads. In Java, the Java Memory Model (JMM) defines the rules and guarantees for how threads interact with memory, ensuring a level of consistency that allows for reliable and predictable behavior.

How Does Memory Consistency in Java Work?

Understanding memory consistency involves grasping concepts like atomicity, visibility, and ordering of operations. Let’s delve into these aspects to get a clearer picture.

Atomicity

In the context of multithreading, atomicity refers to the indivisibility of an operation. An atomic operation is one that appears to occur instantaneously, without any interleaved operations from other threads. In Java, certain operations, such as reading or writing to primitive variables (except long and double), are guaranteed to be atomic. However, compound actions, like incrementing a non-volatile long, are not atomic.

Here is a code example demonstrating atomicity:

public class AtomicityExample {

    private int counter = 0;
    public void increment() {
        counter++; // Not atomic for long or double
    }
    public int getCounter() {
        return counter; // Atomic for int (and other primitive types except long and double)
    }
}

For atomic operations on long and double, Java provides the java.util.concurrent.atomic package with classes like AtomicLong and AtomicDouble, as shown below:

import java.util.concurrent.atomic.AtomicLong;

 

public class AtomicExample {

    private AtomicLong atomicCounter = new AtomicLong(0);

 

    public void increment() {

        atomicCounter.incrementAndGet(); // Atomic operation

    }

 

    public long getCounter() {

        return atomicCounter.get(); // Atomic operation

    }

}

Visibility

Visibility refers to whether changes made by one thread to shared variables are visible to other threads. In a multithreaded environment, threads may cache variables locally, leading to situations where changes made by one thread are not immediately visible to others. To address this, Java provides the volatile keyword.

public class VisibilityExample {

    private volatile boolean flag = false;




    public void setFlag() {

        flag = true; // Visible to other threads immediately

    }




    public boolean isFlag() {

        return flag; // Always reads the latest value from memory

    }

}

Using volatile ensures that any thread reading the variable sees the most recent write.

Ordering

Ordering pertains to the sequence in which operations appear to be executed. In a multithreaded environment, the order in which statements are executed by different threads may not always match the order in which they were written in the code. The Java Memory Model defines rules for establishing a happens-before relationship, ensuring a consistent order of operations.

public class OrderingExample {

    private int x = 0;

    private boolean ready = false;




    public void write() {

        x = 42;

        ready = true;

    }




    public int read() {

        while (!ready) {

            // Spin until ready

        }

        return x; // Guaranteed to see the write due to happens-before relationship

    }

}

By understanding these basic concepts of atomicity, visibility, and ordering, developers can write thread-safe code and avoid common pitfalls related to memory consistency.

Read: Best Practices for Multithreading in Java

Thread Synchronization

Java provides synchronization mechanisms to control access to shared resources and ensure memory consistency. The two main synchronization mechanisms are synchronized methods/blocks and the java.util.concurrent package.

Synchronized Methods and Blocks

The synchronized keyword ensures that only one thread can execute a synchronized method or block at a time, preventing concurrent access and maintaining memory consistency. Here is an short code example demonstrating how to use the synchronized keyword in Java:

public class SynchronizationExample {

    private int sharedData = 0;




    public synchronized void synchronizedMethod() {

        // Access and modify sharedData safely

    }




    public void nonSynchronizedMethod() {

        synchronized (this) {

            // Access and modify sharedData safely

        }

    }

}

While synchronized provides a straightforward way to achieve synchronization, it can lead to performance issues in certain situations due to its inherent locking mechanism.

java.util.concurrent Package

The java.util.concurrent package introduces more flexible and granular synchronization mechanisms, such as Locks, Semaphores, and CountDownLatch. These classes offer better control over concurrency and can be more efficient than traditional synchronization.

import java.util.concurrent.locks.Lock;

import java.util.concurrent.locks.ReentrantLock;




public class LockExample {

    private int sharedData = 0;

    private Lock lock = new ReentrantLock();




    public void performOperation() {

        lock.lock();

        try {

            // Access and modify sharedData safely

        } finally {

            lock.unlock();

        }

    }

}

Using locks allows for more fine-grained control over synchronization and can lead to improved performance in situations where traditional synchronization might be too coarse.

Memory Consistency Guarantees

The Java Memory Model provides several guarantees to ensure memory consistency and a consistent and predictable order of execution for operations in multithreaded programs:

  1. Program Order Rule: Each action in a thread happens-before every action in that thread that comes later in the program order.
  2. Monitor Lock Rule: An unlock on a monitor happens-before every subsequent lock on that monitor.
  3. Volatile Variable Rule: A write to a volatile field happens-before every subsequent read of that field.
  4. Thread Start Rule: A call to Thread.start on a thread happens-before any action in the started thread.
  5. Thread Termination Rule: Any action in a thread happens-before any other thread detects that thread has terminated.

Practical Tips for Managing Memory Consistency

Now that we have covered the fundamentals, let’s explore some practical tips for managing memory consistency in Java threads.

1. Use volatile Wisely

While volatile ensures visibility, it does not provide atomicity for compound actions. Use volatile judiciously for simple flags or variables where atomicity is not a concern.

public class VolatileExample {

    private volatile boolean flag = false;




    public void setFlag() {

        flag = true; // Visible to other threads immediately, but not atomic

    }




    public boolean isFlag() {

        return flag; // Always reads the latest value from memory

    }

}

2. Employ Thread-Safe Collections

Java provides thread-safe implementations of common collection classes in the java.util.concurrent package, such as ConcurrentHashMap and CopyOnWriteArrayList. Using these classes can eliminate the need for explicit synchronization in many cases.

import java.util.Map;

import java.util.concurrent.ConcurrentHashMap;




public class ConcurrentHashMapExample {

    private Map<String, Integer> concurrentMap = new ConcurrentHashMap<>();




    public void addToMap(String key, int value) {

        concurrentMap.put(key, value); // Thread-safe operation

    }




    public int getValue(String key) {

        return concurrentMap.getOrDefault(key, 0); // Thread-safe operation

    }

}

You can learn more about thread-safe operations in our tutorial: Java Thread Safety.

3. Atomic Classes for Atomic Operations

For atomic operations on variables like int and long, consider using classes from the java.util.concurrent.atomic package, such as AtomicInteger and AtomicLong.

import java.util.concurrent.atomic.AtomicInteger;




public class AtomicIntegerExample {

    private AtomicInteger atomicCounter = new AtomicInteger(0);




    public void increment() {

        atomicCounter.incrementAndGet(); // Atomic operation

    }




    public int getCounter() {

        return atomicCounter.get(); // Atomic operation

    }

}

4. Fine-Grained Locking

Instead of using coarse-grained synchronization with synchronized methods, consider using finer-grained locks to improve concurrency and performance.

import java.util.concurrent.locks.Lock;

import java.util.concurrent.locks.ReentrantLock;


public class FineGrainedLockingExample {

    private int sharedData = 0;

    private Lock lock = new ReentrantLock();

    public void performOperation() {

        lock.lock();

        try {

            // Access and modify sharedData safely

        } finally {

            lock.unlock();

        }

    }

}

5. Understand the Happens-Before Relationship

Be aware of the happens-before relationship defined by the Java Memory Model (see the Memory Consistency Guarantees section above.) Understanding these relationships helps in writing correct and predictable multithreaded code.

Final Thoughts on Memory Consistency in Java Threads

Memory consistency in Java threads is a critical aspect of multithreaded programming. Developers need to be aware of the Java Memory Model, understand the guarantees it provides, and employ synchronization mechanisms judiciously. By using techniques like volatile for visibility, locks for fine-grained control, and atomic classes for specific operations, developers can ensure memory consistency in their concurrent Java applications.

The workflow engine offers valuable insights and transparency regarding bug status, while automation saves time and ensures everything flows seamlessly. When an issue transitions from the backlog to completion, developers receive automatic updates. Jira’s automation also lets developers assign bugs automatically and place releases on autopilot.

The way bug tracking in Jira works is straightforward: When a bug is spotted, you create a detailed issue with its own custom workflow. The captured bug can be prioritized according to importance by dragging and dropping it to the to-do column or the backlog, and then assigning it. Engineers can then create a new branch in their chosen source code management software (such as Bitbucket) to begin working on the bug through a Jira ticket. That same ticket will automatically update with new pull requests, mergers, etc., to keep everyone in sync.

To further enhance the bug tracking experience, Jira integrates with many popular third-party tools, including GitHub, Bitbucket, Jenkins, and Slack.
