This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Our list is a little longer because we have also included methods that are referred in options of questions that are not necessarily about String. So to make sure the candidate accepts/rejects such an option confidently, we suggest going the API description of such methods as well.
Also, an important thing to note is most of the methods have meaningful names so don't get overwhelmed by the number of methods. Most of them are really very simple.
