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.
You can post questions on autoboxing, and the one you posted would make a great question for the SCJPtest. My question, however, is are you asking "what is the output?" or "why is the output 'SuccessSuccessFailure'?" (I really didn't want to give away the answer to those who may have wanted to test it and reason it out for themselves.)
