I'm not sure I understand the question. Are you sure you've read and understood the java.util.Random API? (and BTW, it's 'Random', not 'random' - that sort of stuff is very important in Java).
The reason I ask is that I don't see any attempt to call one of its methods in your code.
Normally, I'd suggest using the online tutorials; but unfortunately they still seem to be stuck on using Math.random(), which is vastly inferior to the Random class. This page seems to provide a quick intro with a few examples though.
Isn't it funny how there's always time and money enough to do it WRONG?

Almost the same. The original code didn't print anything if x was exactly equal to 0, 100 or 200. Also, the condition (x < 300) is unnecessary, because r.nextInt(300) will always produce a number less than 300.
