Java Programming Language

Java has long been one of the best known and most popular programming languages.

No special operating system is required to run the programs, just a software environment: The Java Runtime Environment (JRE) from Sun Microsystems.

A large area of application is, for example, the server-side programming of web applications or mobile application development.
