"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

I buy this book for every engineer that starts on my team. - 2009-05-08
Reviewer Rating:
This is the best book on java. If you are planning on using java as a real language for development, you should read this book before you write your first interface or draw your first box on the whiteboard.

I buy this book for everyone who starts on my team. It is really that good.

Avoid concurrency nightmare - 2009-11-03
Reviewer Rating:
This books guide yourself to develop concurrency programs in the right way, giving you advises what to do and what not to do. It's the most complete reference about concurrence in Java. It's really fantastic. Cover from the basics to the complex aspects of concurrency. I strongly recommend this books.

Best Java Book on Threading - 2009-06-08
Reviewer Rating:
I recently bought this book from Amazon. Just finished Chapter 3. This book is full of real-life advice about designing and delivering Thread-safe classes. More importantly, it helps us (Java Developers) to question whether the 3rd party library we use in projects are thread-safe or not and spot concurrency "mousetraps".

This books introduces a topic usually with a "Bad" thread example and then reasons out the potential deficiencies (race conditions, etc.) that may happen when things go wrong with that code. Then (thankfully!) they propose a alternative correct solution in easy to understand code.

This book also addresses a gaping hole in current Javadocs standards followed by devlopers : not clearly mentioning the Thread-safety aspect of the class.

In all a excellent book and a must read along with "Effective Java".

Best concurrency book - 2009-05-26
Reviewer Rating:
This is definitely the best concurrency book for Java out there. It gives you pretty much all the concepts you ever need to know about concurrency in general. From basic concurrency principles to concurrency issues that would arise in almost all concurrent programs, and finally to some optimization techniques. It also provides some in-sights on some of the Java concurrent utility classes provided by the JDK package.

However, this book is not for Java beginners. You need to have an intermediate understanding of Java and some general programming/software engineering concepts. Also, if you are just starting with concurrent programming, this book might be slightly challenging at the beginning. But you should be able to pick it up fairly quickly.

And if you are already a concurrency expert or have quite some understandings about concurrency in general, this book will still solve a lot of the myths out there and may inspire you to further research on some of the topics.

Overall, this is a definite buy if you want to do concurrent programming.

Amazing introduction to multithreaded programming in Java - 2009-04-04
Reviewer Rating:
This book is a must read for anyone who works in multithreaded environment. Even if you don't create threads yourself but use application server or any other environment where multiple threads execute at once, you cannot miss it. This book will tell you why and how synchronization happen - why what you think should work will not and how to read code for multithreaded application. If you never heard about Java Memory Model (JMM) you should not even touch multithreaded applications without reading this book.
