Java Runtime Environment (JRE) enables your computer to run applications and applets that use Java technology. Java technology allows you to work and play in a secure computing environment. Java technology is in cell phones, automobiles, the Mars Rover, and many other places. By downloading it to your computer, you will be able to experience the power of Java software. The Java Virtual Machine is only one aspect of Java software that is involved in web interaction. The Java Virtual Machine is built right into your Java software download, and helps the Sun JRE run Java applications.
