If you’re embarking on a career in software development, or if you’re already an established developer, low-code and no-code development platforms are going to have a significant impact on  your life. The good news is that it likely won’t be a negative one. As the name suggests, low-code and no-code platforms allow people to develop software with little or no coding skills. The platforms provide...

The Entity Classes It is easy to transform a POJO into an entity class via annotation. In fact, a single annotation, @Entity, is enough to designate any POJO as an entity class. For example, examine a regular class such as follows: public class Book {   private int id;   private String title; private String publisher; public Book() {} public Book(int...

Enterprise applications often deal with operations such as the collecting, processing, transforming, and reporting of a large amount of data. These data are typically stored in a database server in a particular location and retrieved on demand. The application is responsible for processing the data from the database and finally present them for client consumption. But, the intricacies involved in mitigating the data exchange...

Green Thread Model The green thread is the simplest threading library of JVM scheduled threads. In this model, each thread is an abstraction within the VM. The JVM is completely responsible for its creation and manages the process of context switching within a single process of the operating system. In other words, green threads are the sole property of JVM and its implementation. The underlying...

Introduction During this article series, I have shown you the tools needed to create and set up Alexa skills. I have also shown you how to create an Amazon skill in .NET. The next logical step is to talk about testing Alexa skills. Let's see what options are available. There are multiple options available for testing an Amazon skill: The Utterance profiler The simulator on the Test page in...

Overview The process of serialization converts the state of an object into a stream of bytes. If we want to store an object in a file, it is necessary to convert it into bytes. These bytes then can be restored into an object, its original form, with the process called deserialization. This is how object persistence takes place. The process of serialization also needs to...

Overview In Java, it is possible to declare a class within another class. This is called a nested class. The visibility and scope of the nested class is bounded by the class within which it is declared. Thus, if a class B is declared within class A, it means that the existence of the class B is dependent on the existence of class A. Also,...

Inheritance is one of the primary capabilities of object-oriented programming (OOP) languages, such as Java. It is a fundamental technique for organizing classes in a manner that enhances the capability of class reuse in software design. Multiple inheritance is one of the many types of inheritance and is an important tenet of the inheritance mechanism. But, it is notorious for creating ambiguous relationships among...
