Description:This is a great book to prepare for the SCJP exams. The pity is that it was designed for SCJP 1.4. But where the subject matter for SCJP 5 is the same as for SCJP 1.4 I find this book better than the Sierra/Bates book. The discussion is very complete and thorough. Very good discussion of nested classes, threads, etc. But you need the S/B book for generics and the newer stuff.
