If you'd like to learn the new features in Java SE 5.0 and/or pass the Sun Certified Java Programmer Upgrade Exam (CX-310-056), then check out the new book "Fast Track to Sun Certified Java Programmer (SCJP) 5.0 Upgrade Exam" at http://www.agileskills2.org/FTSCJP. The first 25 pages are freely available there, so you can judge it yourself.
The book covers all the Java SE 5.0 new features required in the exam; you don't need to read about the features you already know. 117 review questions and mock exam questions are included.
