What Is Java Used For?

The Java programming language allows users to play games, interact with maps, explore virtual worlds and transfer data, among other uses. It has an architecture that makes it usable across different types of platforms, including computers, mobile devices, televisions and media players.

Many desktop applications rely on having Java installed in the system in order to run. Online content and websites, such as Twitter, Tumblr, LinkedIn and Google, also depend on Java to provide services to users. In addition, Java is the foundation of applications that run on Android mobile devices. It is a proven tool for meeting performance and scalability requirements of companies that run heavy-duty servers. Java is a cross-platform system, which means any Java software that's built on one platform can also run on another platform.

The popularity of Java is one reason why it's a practical language for teaching beginners how to program. Java gives programmers control over a platform's file system, graphics and sound configurations in order to build complex programs. Because Java encourages writing code by using the object-oriented programming paradigm, programmers can easily learn other languages that also use the object-oriented approach. Programmers with Java experience can easily find employment in high-profile companies, such as Amazon, IBM and eBay.
