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.
It is brilliant. I heartily recommend it. His explanations of complex topics are crystal clear and complete.

The first volume which is "Java Rules" is available for less than $5 on the amazon marketplace!
