A Programmer's Guide to Java SCJP Certification A Comprehensive Primer (3rd Edition)

The exam for the Sun Certified Programmer for Java Platform, Standard Edition 6, has changed considerably since the second edition of this book was published. The most noticeable change in the current version of the Sun Certified Java Programmer (SCJP) 1.6 exam is the inclusion of the features of Java 5, and the shifting of emphasis towards analyzing code scenarios, rather than individual language constructs. In our opinion, the new exam demands an even greater understanding and actual experience of the language, rather than mere recitation of facts. Proficiency in the language is the key to success.

This book cuts through all the noise and shows them which utilities are most useful, and which options most important. And it contains examples, lot's and lot's of examples. This is not just a reprint of the man pages.
