This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
Two largely unrelated questions on the OCJP6 exam.
1. Somebody told me that for the 60 questions you answer on the exam, Oracle don't mark about 5 of them, so you only get marked on say 55 not 60 (meaning of course each question is worth much more in percentage). Can somebody clarify this and hazard a guess as to why on earth this is the case?
2. Can somebody tell me whether I need to learn about Map.Entry for NavigableMaps and all the related methods? I was doing some whizlabs stuff and there are a lot of questions on NavigableMaps and many include topics on methods/usage that is completely missing from the Kathy OCJP6 book, one such thing is Map.Entry (to name but one of many omissions/questions I'm getting). To be honest, I have a copy of OCJP5 book and for all the alterations to the 5 book you can spot them a mile off as they are clearly very hurriedly written and contain sparse detailed information unlike the rest of the book.
