after initial issues with sellers that did not reply to 5 emails the book arrived in time and in very good status.

Not the best for learning about Java Threads, but you can use it as a reference when you have a different better book to understand all of the technical jargon...

This book provides answers to questions on threading that have confused me for a long time:
1. Why use a thread pool and why not?
2. How expensive are synchronization, thread creation and concurrent collections?
It clears up a lot of myths and rumors I have heard.

Before I bought this book, I had to prototype threading examples in my own workspace, setting up race conditions and such, but it was a lot of work and left a lot unexplained.
Scott Oaks, the author, did a good job of describing the synchronization process and the various Object methods relating to threading protocol. There were plenty of good examples, and clarification on several minor technical points including: how the wait/notify methods release monitors, the determinability of prioritization, and the practical uses of threadgroups. If you have nagging questions, you may find them answered here.
O'Reilly books are small-sized, which makes for easy carrying and storage. Little if any of their content is redundant or inaccurate. Given how dry the material is, O'Reilly astounds me by consistently finding authors who can write well, have something to say, and whose works can be read in a sitting.
Of course, it's important to mention that some things have changed since the first edition of this book. Methods like resume(), suspend(), and stop() have been deprecated due to their unpredictablity; the JVM will now enable programmers to address multiple processes; and there are a variety of classes which facilitate thread administration. A newer edition will bring you up to speed on those details, but this first edition is still a valid reference in all other respects.

< review="" of="" the="" 3rd="" edition="" />>
This book is written for developers who are targeting the second wave of java programs - Intermediate to advanced level programmers will be able to get best value out of this book. Developers who are already familiar with the basics of java may also be able to get some value, but if you are completely new to java, please look elsewhere.
Without any futher ado, i will dive right into the deep end of the pool. This book is partitioned into 4 logical sections, though it is not explicit in the TOC.
1. Important Threading Concepts:
In this section, the author prepares us with the fundamentals of creating and managing a thread, basic synchronization concepts, synchronized keyword, lock mechanism, thread communication using wait-notify and condition-variables, minimal synchronization using volatile keyword and atomic variables, advanced synchronization classes like Barrier, Semaphore, CountdownLatch, etc. Chapters 1 through 6 underwrite this section and this is by-far the best part of the book.
2. Thread Pools/Schedulers:
This section first lectures around how thread scheduling materializes in java and how it is related to the underlying Operating System. Next, you are guided through a tour of Thread Pools and Task Schedulers that will enlighten us with quite a few new classes in java 5. Chapters 9 through 11 cover this section.
3. Threading and other Java APIs:
This section details how the threading API plays with other inbuilt java APIs like Collections, IO and Swing. Chapters 7,8 and 12 cover this section.
4. Misc topics:
Some miscellaneous thread topics like ThreadGroup, Security, Class Loading, Exception Handling and Performance are addressed in this section. Chapters 13, 14, and 15 cover this section.
Though this book wasn't an easy read, i found it extremely encouraging to have ONE comprehensive manual to understand both the threading concepts and the new java 5 inclusions. I recommend this book to anyone who is in the middle of a complex multi-threaded system or wishes to create one.
