Java Runtime Environment 1.6.0.18

Java Runtime Environment allows you to run applications called applets that are written in the Java programming language. These applets allow you to have a much richer experience online than simply interacting with static HTML pages.

Java Plug-in technology, included as part of the Java 2 Runtime Environment, Standard Edition (JRE), establishes a connection between popular browsers and the Java platform. Java allows applications to be downloaded over a network and run within a guarded sandbox. Security restrictions are easily imposed on the sandbox.

Many cross platform applications also require Java to operate properly.
