Java

Java is an object-oriented language that is very similar to C++, however, Java has been simplified to eliminate language features that cause many of the common programming errors. The Java source code files, files that have a .java extension, are compiled into a format called bytecode. The bytecode files have a .class extension. The .class files can be executed by a Java interpreter.

Compiled Java code can be executed on most computers because Java interpreters and runtime environments, known as the Java Virtual Machines (VMs), exist for most operating systems, including UNIX, the Macintosh OS, and Windows. In addition, Bytecode can be converted directly into machine language instructions by what is called a just-in-time compiler (JIT).

Java is a general purpose programming language with a number of features that make the language well suited for use on the World Wide Web. Small Java applications are called Java applets and can be downloaded from a Web server and run on your computer by a Java-compatible Web browser, such as Netscape Navigator or Microsoft Internet Explorer.
