Wow, a very cool website was just brought to my attention. Nick Parlante, of Stanford, has pulled together a website where you can hone your Java skills. Created with the theory that you learn by doing and the more you do it, the better you get, JavaBat provides a set of programming examples that give you immediate feedback.

For example: java -Djava.ext.dirs=/foo/bar/baz:/bleem/grumpf MyApp See the Extension Mechanism Architecture specand...
