This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori 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).
