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.
I can't remember seeing much on the exam about annotations although they are used more and more in the stuff i use everyday (spring, hibernate etc). Have a search for @SuppressWarnings and @Override for some common ones.
