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.
Tonight, I took the IBM 340 pre-assessment test in order to get the free voucher. Previously I searched for those questions at JavaRanch but surprisingly Prometric asked some brand new ones (20 - almost half of the required questions).
Fortunately I passed because I was studying this subject and I was able to answer some of these questions, Below, I listed all of them:
