A program targeting the Java platform needs two components to be present on its host: a Java virtual machine, and a set of class libraries providing any services on which it depends. Sun's distribution of their JVM and their implementation of the standard classes is known as the Java Runtime Environment (JRE).

û=== Java Virtual Machine ===

The heart of the Java platform is the concept of a common "virtual" processor that executes Java [[bytecode]] programs. This bytecode is the same no matter what hardware or operating system the program is running under. The Java platform provides an [[interpreter (computing)|interpreter]] called the [[Java virtual machine]] (JVM), which translates the Java bytecode into native processor instructions at run-time. This permits the same application to be run on any platform that has a virtual machine available.
