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.
On pg 518 in your book you are missing a ; at the end of a line of sample code. System.out.println("Not enough in account for " + Thread.currentThread().getName() + " to withdraw " + acct.getBalance()) I went to wickedlysmart.com to report this. Your website states to email you with any corrections, however I did not see your email address on the site. I know that this is a small typo but I just thought I would point it out.
