This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
You might also consider Bert's book of Practice Exams. ISBN: 978-0-07-226088-5. Of course he's the B in "K&B". I didn't work the whole book but, if I had, I'd be a more expert Java programmer than I am now. (I'd have to be!)
