Raves for the First Edition!

 

I sure wish I had this book ten years ago. Some might think that I dont need any Java books, but I need this one.

James Gosling, fellow and vice president, Sun Microsystems, Inc.

 

An excellent book, crammed with good advice on using the Java programming language and object-oriented programming in general.

Gilad Bracha, coauthor of The Java Language Specification, Third Edition

 

10/10anyone aspiring to write good Java code that others will appreciate reading and maintaining should be required to own a copy of this book. This is one of those rare books where the information wont become obsolete with subsequent releases of the JDK library.
Peter Tran, bartender, JavaRanch.com

 

The best Java book yet written.... Really great; very readable and eminently useful. I cant say enough good things about this book. At JavaOne 2001, James Gosling said, Go buy this book! Im glad I did, and I couldnt agree more.
Keith Edwards, senior member of research staff, Computer Science Lab at the Palo Alto Research Center (PARC), and author of Core JINI (Prentice Hall, 2000)

 

This is a truly excellent book done by the guy who designed several of the better recent Java platform APIs (including the Collections API).
James Clark, technical lead of the XML Working Group during the creation of the XML 1.0 Recommendation, editor of the XPath and XSLT Recommendations

 

Great content. Analogous to Scott Meyers classic Effective C++. If you know the basics of Java, this has to be your next book.
Gary K. Evans, OO mentor and consultant, Evanetics, Inc

 

Josh Bloch gives great insight into best practices that really can only be discovered after years of study and experience.
Mark Mascolino, software engineer

 

This is a superb book. It clearly covers many of the language/platform subtleties and trickery you need to learn to become a real Java master.
Victor Wiewiorowski, vice president development and code quality manager, ValueCommerce Co., Tokyo, Japan

 

I like books that under-promise in their titles and over-deliver in their contents. This book has 57 items of programming advice that are well chosen. Each item reveals a clear, deep grasp of the language. Each one illustrates in ...
