SCJP Sun Certified Programmer for Java 6 Study Guide (Exam 310-065)

This is a classic study guide for anyone looking to dive into Java 6. It's the SCJP Sun Certified Programmer for Java 6 guide by Kathy Sierra and Bert Bates, which was always the go-to resource for this certification. It includes the practice exam CD as well. Used, but the pages are clean and it's a great piece of programming history or a solid reference for legacy systems.
