This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
If you know the 6 patterns listed in the objectives, you should be able to answer all the patterns questions. Sometimes on these exams you might find APIs or such that you don't expect - that usually means the exam is trying to distract you from the real intention of the question. So, if you see a pattern not listed in the objectives - don't panic - find out what's really going on!
Spot false dilemmas now, ask me how!
