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.
My crystal ball is in the shop being repaired this week so I'm unable to gaze into your computer and see your source code. If you could help me out and just paste the relevant bits of your code here, that would be super great.
