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.
From the site "....unique about this treasure hunt is everything about it is Java. You run around collecting and solving Java clues. The hunt is primarily aimed at those who are new to Java but should be fun even for experienced folks!"
