This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
While Cade gives a few sample questions, he is more of a study guide than a complete reference. The other book says it has more sample questions. But the reviews on Amazon are horrible and I haven't seen people in this forum referring to it. (I bought and read the Cade book).
