Java is a programming language and computing platform that lets developers code once and run it anywhere. Java is a class-based, object-oriented programming language that was designed to be portable. It's a general programming language that was intended for application developers to create applications that can run on multiple platforms. There are millions of software applications that can be operated by Java technology. It's used to develop a wide variety of computer programs including applications and applets, video games, animations, and multimedia. For this reason, many companies prefer to use Java technology because of its efficiency and economy, as well as the ability to store data locally or on different databases.
The software, which was originally developed by Sun Microsystems in the 1990s, has become a foundational language for other uses including applications, applets, web services, and server-side software. It is more than just a programming language, but it is also a platform i.e., a virtual machine that creates a run time environment on the computer where java-based applications can be executed.
