How to Install Java 1.5

Originally developed by Sun Microsystems, Java technology allows programmers to create applications capable of running on nearly any operating system. Instead of creating separate programs for the Windows, Mac OS X and Linux platforms, it lets them write code only one time. All end users have to do is install the Java Runtime Environment (JRE) software on their computer one time and Java programs will run without issue. If you want to install version 1.5 of the JRE on your system, download the installer program from the Java website and then run through its brief setup process.
