Kathy Sierra was a lead developer for the SCJP exam for Java 5 and Java 6. Kathy worked as a Sun master trainer, and in 1997, founded JavaRanch.com, the worlds largest Java community website. Her bestselling Java books have won multiple Software Development Magazine awards, and she is a founding member of Oracles Java Champions program.

These days, Kathy is developing advanced training programs in a variety of domains (from horsemanship to computer programming), but the thread that ties all of her projects together is helping learners reduce cognitive load.

Bert Bates was a lead developer for many of Suns Java certification exams, including the SCJP for Java 5 and Java 6. Bert was also one of the lead developers for Oracles OCA 7 and OCP 7 exams. He is a forum moderator on JavaRanch.com and has been developing software for more than 30 years (argh!). Bert is the co-author of several bestselling Java books, and hes a founding member of Oracles Java Champions program. Now that the book is done, Bert plans to go whack a few tennis balls around and once again start riding his beautiful Icelandic horse, Eyrraros fra Gufudal-Fremri.

This is the fourth edition of the book that weve cooked up. The first version we worked on was for Java 2. Then we updated the book for the SCJP 5, again for the SCJP 6, and now for the OCA 7 and OCP 7 exams. Every step of the way, we were unbelievably fortunate to have fantastic, JavaRanch.com-centric technical review teams at our sides. Over the course of the last 12 years, weve been evolving the book more than rewriting it. Many sections from our original work on the Java 2 book are still intact. On the following pages, wed like to acknowledge the members of the various technical review teams who have saved our bacon over the years.

Johannes de Jong has been the leader of our technical review teams forever and ever. (He has more patience than any three people we know.) For the Java 2 book, he led our biggest team ever. Our sincere thanks go out to the following volunteers who were knowledgeable, diligent, patient, and picky, picky, picky!

Rob Ross, Nicholas Cheung, Jane Griscti, Ilja Preuss, Vincent Brabant, Kudret Serin, Bill Seipel, Jing Yi, Ginu Jacob George, Radiya, LuAnn Mazza, Anshu Mishra, Anandhi Navaneethakrishnan, Didier Varon, Mary McCartney, Harsha Pherwani, Abhishek Misra, and Suman Das.
