You can include animations, games, interactive transaction processing - the possibilities are almost unlimited. Java also allows you to write large-scale application programs that you can run on any computer with an operating system environment in which the language is supported. This applies to the majority of computers in use today. You can even write programs that will work both as ordinary applications and as applets. Java has matured immensely in recent years, particularly with the introduction of java 2. The breadth of function provided by the standard core java has grown incredibly. Java provides you with comprehensive facilities for building application with an interactive GUI, extensive image processing and graphics programming facilities, as well as support for accessing relational databases and communications with remote computers over a network. Release 1.4 of java added a very important additional capability, the ability to read and write XML. Just about any kind of application can now be programmed effectively in java, with the implicit plus of complete portability. ...read more.
