I agree that the best
book may be "Kathy & Bert's" book, usually referred to in this JavaRanch SCJP forum as, "K & B":
Title: "SCJP Sun Certified Programmer for Java 5 Study Guide (Exam 310-055) (Certification Press Study Guides) (Paperback)"
ISBN-10: 0072253606
ISBN-13: 978-0072253603
You can follow the following link to buy the book on Amazon.com or to view the reviews of Amazon.com customers.
K & B Book There is another study guide available online by another SCJP 5.0 expert, Marcus Green. He calls his online study guide "Tiger Tamer" which is named after the code-name of Java version 5.0 which is called "Tiger". I have heard good things about "Tiger Tamer". I haven't read it myself, but I know that it has the advantage of being able to be downloaded immediately. With books from Amazon.com, you'd have to wait to get the book in the mail.
Tiger Tamer Download IMHO, Marcus Green has the best practice exams for the SCJP 5.0.
Marcus Green's Online Practice Exams (Try the first one for free!) Whatever study materials and practice exams, make sure that they cover Java version 5.0 (also known as version 1.5).
