The '''Java''' programming language, developed by Sun Microsystems, is a language aimed at allowing high performance, cross-platform 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]] of a Java program into your processors' native machine code during execution. This native code translation is done via a [[Just-In-Time|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) |
|||
* High performance (Java code running with a modern JIT is often comparable to the speed of [[C plus plus|C++]]) |
|||
* Comprehensive class library |
|||
* Automatic memory management |
|||
* Huge 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 [[Java Server Pages|JSP]]) and [[applets]] embedded in web pages. |
|||
According to a variety of [http://www.tiobe.com/tpci.htm sources], Java is currently the most popular programming language in the world. |
