Java source files (.java files) are typically [[Compiler\|compiled]] to an intermediate [[bytecode]] ~~language~~(all platform) executable (.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 [[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.

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 [http://~~java~~www.~~sun~~oracle.com/technetwork/java/javase/~~reference~~documentation/~~api~~index.~~jsp~~html documented]) * [[garbage collection\|Automatic memory management]] * Large user community * Well supported by the [[open source]] community and commercial industry ([[Sun Microsystems\|Sun]], [[IBM]], [[Oracle]], HP, BEA, [[~~Mac~~Apple ~~OS X\|Apple~~Inc]], 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. 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.g. Java for memory allocation, C++ for numerical operations). ~~An extensive summary of comparisons between Java and C++ can be found [[wp:Comparison of Java and C++\|on Wikipedia]].~~ An extensive summary of comparisons between Java and C++ can be found [[wp:Comparison of Java and C++\|on Wikipedia]]. According to some [http://www.tiobe.com/tpci.htm sources], Java is currently one of the most popular programming ~~language~~languages in the world.
