I have written quite a few simple apps and applets but haven't been exposed to jars much. How does the jar tool work and what exactly does it accomplish for me (why would I want to bother using it?) I understand that it does some packaging and compression, but does it (or could it) eliminate the need for an unknown enduser to have the JDK installed?

Hi K,
The end user doesn't need to have the JDK installed, but they would need an appropriate JRE (Java Runtime Environment - the thingy that understands the java bytecode)
Try this page for an explanation of what you can do with the jar command.
 
Don't get me started about those stupid light bulbs.
