Java source files (.java files) are typically [[Compiler|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.▼

Java source files (.java files) are typically [[Compiler|compiled]] to an intermediate [[bytecode]] (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.

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://www.oracle.com/technetwork/java/javase/documentation/index.html documented])
* [[garbage collection|Automatic memory management]]

* Well supported by the [[open
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 (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]].
According to a variety of [http://www.tiobe.com/tpci.htm sources], Java is currently the most popular programming language in the world.▼
