Java is a general-purpose programming language with object-oriented features, originally created to develop desktop applications. In time it has evolved to be used in the creation of many types of applications, including web development, mobile app development, video game creation, and server-side applications – to name but a few.
Java code is usually written in a code editor or an integrated development environment (IDE), such as Notepad++, Eclipse, or Visual Studio Code. Java code gets compiled into bytecode, making it possible to run on any machine with a Java Virtual Machine (JVM) installed. This follows the philosophy of WORA or Write Once, Run Anywhere that has made Java so popular. Java is statically-typed, meaning that the type of a variable must be declared when it is first defined. Java further uses keywords like public, private, and static to define the scope, access, and behavior of variables, methods, and classes.
