The Java programming language, developed by Sun Microsystems, is a language aimed at allowing "high-performance", virtual application development.

Java source files (.java files) are typically compiled to an intermediate bytecode language (.class files) and executed by a Java Virtual Machine. Most modern JVMs further compile the bytecode into your processor's native machine code during execution. This native code translation is done via a JIT compiler that is built in to the JVM. Some Java compilers (such as GCJ) can compile Java code to native machine code ahead-of-time rather than just-in-time.

The primary benefits of Java are:

Cross-platform (Write Once, Run Anywhere (if all of the libraries are ported))
Comprehensive class library (which is thoroughly documented)
Automatic memory management
Large user community
Well supported by the open source community and commercial industry (Sun, IBM, Oracle, HP, BEA, Apple, etc.)

Java is used in a variety of environments including desktop applications, embedded device (PDA and wireless phone) applications, server-side web page serving applications (as JSP), and applets embedded in web pages.

There are a variety of arguments regarding Java's performance compared to other popular languages like C++. Some come to the conclusion that the programmer's choices make a bigger difference on performance in each language. Most show that each language is better than the other at specific types of operations (i.e. Java for memory allocation, C++ for numerical operations). An extensive summary of comparisons between Java and C++ can be found on Wikipedia.

According to some sources, Java is currently the most popular programming language in the world.
