My goal is to prepare for The Sun Certified Programmer for Java 2 Platform 5.0 certification exam. I have documented Java API before but have found myself reverse engineering code to understand what a particular class or method is supposed to do. I find that I am searching Google about hash maps and factory classes.

“Achieving this certification provides clear evidence that a programmer understands the basic syntax and structure of the Java programming language and can create Java technology applications that run on server and desktop systems using J2SE 5.0. “

Yes! This sounds great–where do I start?
