Editorial Review:Product Description:'I was fortunate indeed to have worked with a fantastic team on the design and implementation of the concurrency features added to the Java platform in Java 5.0 and Java 6. Now this same team provides the best explanation yet of these new features, and of concurrency in general. Concurrency is no longer a subject for advanced users only. Every Java developer should read this book.' --Martin Buchholz JDK Concurrency Czar, Sun Microsystems 'For the past 30 years, computer performance has been driven by Moore's Law; from now on, it will be driven by Amdahl's Law. Writing code that effectively exploits multiple processors can be very challenging. Java Concurrency in Practice provides you with the concepts and techniques needed to write safe and scalable Java programs for today's--and tomorrow's--systems.' --Doron Rajwan Research Scientist, Intel Corp 'This is the book you need if you're writing--or designing, or debugging, or maintaining, or contemplating--multithreaded Java programs. If you've ever had to synchronize a method and you weren't sure why, you owe it to yourself and your users to read this book, cover to cover.'--Ted Neward Author of Effective Enterprise Java 'Brian addresses the fundamental issues and complexities of concurrency with uncommon clarity. This book is a must-read for anyone who uses threads and cares about performance.' --Kirk Pepperdine CTO, JavaPerformanceTuning.com 'This book covers a very deep and subtle topic in a very clear and concise way, making it the perfect Java Concurrency reference manual. Each page is filled with the problems (and solutions!) that programmers struggle with every day. Effectively exploiting concurrency is becoming more and more important now that Moore's Law is delivering more cores but not faster cores, and this book will show you how to do it.' --Dr. Cliff Click Senior Software Engineer, Azul Systems 'I have a strong interest in concurrency, and have probably written more thread deadlocks and made more synchronization mistakes than most programmers. Brian's book is the most readable on the topic of threading and concurrency in Java, and deals with this difficult subject with a wonderful hands-on approach.This is a book I am recommending to all my readers of The Java Specialists' Newsletter, because it is interesting, useful, and relevant to the problems facing Java developers today.' --Dr. Heinz Kabutz The Java Specialists' Newsletter 'I've focused a career on simplifying simple problems, but this book ambitiously and effectively works to simplify a complex but critical subject: concurrency. Java Concurrency in Practice is revolutionary in its approach, smooth and easy in style, and timely in its delivery--it's destined to be a very important book.' --Bruce Tate Author of Beyond Java 'Java Concurrency in Practice is an invaluable compilation of threading know-how for Java developers. I found reading this book intellectually exciting, in part because it is an excellent introduction to Java's concurrency API, but mostly because it captures in a thorough and accessible way expert knowledge on threading not easily found elsewhere.' --Bill Venners Author of Inside the Java Virtual Machine Threads are a fundamental part of the Java platform. As multicore processors become the norm, using concurrency effectively becomes essential for building high-performance applications.Java SE 5 and 6 are a huge step forward for the development of concurrent applications, with improvements to the Java Virtual Machine to support high-performance, highly scalable concurrent classes and a rich set of new concurrency building blocks. In Java Concurrency in Practice, the creators of these new facilities explain not only how they work and how to use them, but also the motivation and design patterns behind them. However, developing, testing, and debugging multithreaded programs can still be very difficult; it is all too easy to create concurrent programs that appear to work, but fail when it matters most: in production, under heavy load. Java Concurrency in Practice arms readers with both the theoretical underpinnings and concrete techniques for building reliable, scalable, maintainable concurrent applications. Rather than simply offering an inventory of concurrency APIs and mechanisms, it provides design rules, patterns, and mental models that make it easier to build concurrent programs that are both correct and performant.This book covers: *Basic concepts of concurrency and thread safety *Techniques for building and composing thread-safe classes *Using the concurrency building blocks in java.util.concurrent *Performance optimization dos and don'ts *Testing concurrent programs *Advanced topics such as atomic variables, nonblocking algorithms, and the Java Memory Model

you're not threadsafe
you can't just synchronize everything... and that's the point of this book. synchronizing is critical but most of us do it incorrectly without a thorough understanding of the jvm. this book has given me some useful concurrency patterns which are sufficient for good programming practice. the part of the book you need to retain is the 'what' to do, the rest of the 'why' to do it is useful but not critical to improve your code.

The definitive guide to concurrency with Java
Prior to this book, I spent many years trying to understand concurrency with Java, but I failed. During that time, I actually read four books.
When it comes to concurrency (thread safety and multi-threading), this book is a definitive guide. During the past two years, I have been constantly reading this book. I am still learning.
If you are not familiar with thread safety and Java memory model (as it was my case), you will probably struggle with the first chapters. But it is worth it!
I absolutely recommend this book.

This book build understanding in concurrency from ground up
This book is an essential resource for developer using the java.util.concurrency classes. It is written in a logical path that allows the reader to learn and understand not just the classes to use in writing concurrent applications but also why to write them using approach A versus B versus C.
The use of negative examples is really what makes this book great.
Although certain parts are a real brain tease (with certain pages taking 20-30 minutes of examination to fully understand) you come out with deep understanding that is lasting.
Bravo!

Superb book.
Having recently required to use Java in my work I needed a book to help explain the use of concurrency in Java. I have used C++ and Ada extensively in the defence environment for many years working on many multithreaded systems. For concurrency concepts, the book Concurrency in Ada by Burns and Wellings is still the bench mark, however while this is a Java book many of it concepts apply to any multithreaded language. This is a superb book.

Excellent primer for an oft overlooked and misunderstood topic
The authors correctly point out that this topic, once the realm of advanced programming specialists, is now of concern to all programmers. Technology and the Java language both demand that software artisans understand concurrency and building thread-safe applications. The authors begin with some basics concerning concurrency and defining terms. This is essential since it seems an area where every software engineer seems to have their own definitions and assumptions. With the ground work complete, the authors continue on with various approaches to thread-safety and design considerations.
Included is a discussion of GUI development considerations, performance considerations, and testing strategies. Within an advanced topics section the authors cover explicit locks, custom synchronizers, and the Java memory model with respect to concurrency issues.
The writing style is clear, concise, and readable. Well worth the investment for the beginner or advanced student and sure to be referred to again and again in the future.
