When I went to JavaOne 2005 in SF one of the sessions I attended was the Java Puzzlers presentation. Joshua Bloch and Neal Gafter did a really good presentation. I also recently finished the best Java book I've ever read called Effective Java that Joshua Bloch wrote a few years ago. I didn't make the connection until today.

Anyway, I found Joshua Bloch's work very interesting and I saw this article called: Seeing Shouldn't Be Believing: Solving Java Puzzlers With Google's Joshua Bloch. Check it out.

On a parting note I would just like to say that the Car Talk references they use are lame. I wish they would stop doing that during their presentations. Car Talk itself is OK... just not the parities of it with the Java Puzzlers.
