I bought this book when I was studying for the SCJP2 exam. I was worried that if the exam had a lot on threads I might not know the nitty-gritty particulars. As it turns out, Java threads are pretty simple. But! This book points out the details that can trip you up if you're not careful! Reading this book not only made Java threads rock solid in my head, but makes a great reference for when you jump into tricky threading waters.(trailboss Jan 2000)
You need to learn more about Threads, so you need this book. It goes into great detail and will give you the mechanics of Threads in Java. If you're interested in patterns and the more subtle design issues of Threads, then you should also check out the Doug Lea "Concurrent Programming in Java" book, but start with the Oaks/Wong book first! [little warning: in some places "Java Threads" oversimplifies, and it doesn't offer the very lowest level of detail you could hope for, but it's still the best place to start]. This new Second Edition is updated for Java2, and includes new material and corrections to the earlier book.(cowgirl May 1999)
This is one of the books in my book container. I often try to serialize some of the concepts of Java Threads into my brain.
This very nice books which gives you introduction to JVM and Java Platform in general.
