What is Java programming language and what is it used for?

Java is a popular high-level programming language that is used to create desktop, web and mobile applications, games, and more. It was first introduced by Sun Microsystems in 1995 and is now owned by Oracle Corporation.

Java is known for its platform independence, meaning that programs written in Java can run on any device that has a Java Virtual Machine (JVM) installed, regardless of the underlying hardware and software architecture. This makes Java a popular choice for developing cross-platform applications.

Java is an object-oriented language, which means that it is based on the concept of objects that contain data and methods that operate on that data. Java programs are typically compiled into bytecode, which can be run on any device with a JVM installed.

Java is used in a wide range of applications, including web applications, mobile apps, desktop applications, games, and more. It is also used for server-side programming, scientific computing, and big data processing. Java is one of the most widely used programming languages, and is especially popular for enterprise applications and Android app development.
