Java is a programming language that lets people create applets. Applets are programs attached to websites that move from computer to computer all around the Internet. They are great because they do not have to be installed and work on all types of computers, it does not matter if you have a Mac, PC, Windows NT, Linux, etc... Since this site is mainly about HTML I have provided links to other websites were you can find useful information about learning Java. I have also provided free java files if you click here.
