I'd rather not, since it's covered in every beginning book on the language, that you can find with a simple one or two argument google search, and that has been covered in forums plenty of times. But as a courtesy, here are some links:
Java null from WikiBooks
Java this from Sun

Yes, in any basic explanation material of Java you can find what those means. I love Suns' documentation in this instance.

Captain gives a nice place to you. And thanks captain for the second link. I never read it before.
