"I used to be lucky certainly to have labored with a lovely workforce at the layout and implementation of the concurrency gains further to the Java platform in Java 5.0 and Java 6. Now this similar staff offers the easiest clarification but of those new beneficial properties, and of concurrency typically. Concurrency isn't any longer a subject matter for complex clients simply. each Java developer should still learn this book."
--Martin Buchholz
JDK Concurrency Czar, sunlight Microsystems

"For the previous 30 years, desktop functionality has been pushed by means of Moore's legislations; any further, it is going to be pushed by way of Amdahl's legislation. Writing code that successfully exploits a number of processors could be very tough. Java Concurrency in Practice will give you the options and methods had to write secure and scalable Java courses for today's--and tomorrow's--systems."
--Doron Rajwan
Research Scientist, Intel Corp

"This is the ebook you wish in case you are writing--or designing, or debugging, or protecting, or contemplating--multithreaded Java courses. If you have ever needed to synchronize a mode and also you were not definite why, you owe it to your self and your clients to learn this e-book, hide to cover."
--Ted Neward
Author of Effective firm Java

"Brian addresses the elemental concerns and complexities of concurrency with unusual readability. This e-book is a must-read for an individual who makes use of threads and cares approximately performance."
--Kirk Pepperdine
CTO, JavaPerformanceTuning.com

"This e-book covers a really deep and sophisticated subject in a really transparent and concise means, making it the precise Java Concurrency reference handbook. every one web page is stuffed with the issues (and solutions!) that programmers fight with each day. successfully exploiting concurrency is changing into progressively more very important now that Moore's legislations is offering extra cores yet now not speedier cores, and this publication will assist you to do it."
--Dr. Cliff Click
Senior software program Engineer, Azul Systems

"I have a powerful curiosity in concurrency, and feature most likely written extra thread deadlocks and made extra synchronization errors than such a lot programmers. Brian's e-book is the main readable concerning threading and concurrency in Java, and bargains with this tough topic with a superb hands-on strategy. it is a e-book i'm recommending to all my readers of The Java experts' Newsletter, since it is fascinating, important, and correct to the issues dealing with Java builders today."
--Dr. Heinz Kabutz

"I've targeted a occupation on simplifying easy difficulties, yet this publication ambitiously and successfully works to simplify a fancy yet severe topic: concurrency. Java Concurrency in Practice is innovative in its process, delicate and simple fashionable, and well timed in its delivery--it's destined to be an important book."
--Bruce Tate
Author of Beyond Java

" Java Concurrency in Practice is a useful compilation of threading knowledge for Java builders. i discovered examining this publication intellectually interesting, partially since it is a wonderful creation to Java's concurrency API, yet often since it captures in a radical and obtainable approach specialist wisdom on threading no longer simply stumbled on elsewhere."
--Bill Venners
Author of Inside the Java digital Machine

Threads are a basic a part of the Java platform. As multicore processors turn into the norm, utilizing concurrency successfully turns into crucial for development high-performance purposes. Java SE five and six are a major leap forward for the advance of concurrent functions, with advancements to the Java digital computing device to help high-performance, hugely scalable concurrent periods and a wealthy set of recent concurrency construction blocks. In Java Concurrency in Practice , the creators of those new amenities clarify not just how they paintings and the way to take advantage of them, but additionally the inducement and layout styles at the back of them.

However, constructing, trying out, and debugging multithreaded courses can nonetheless be very tricky; it's all too effortless to create concurrent courses that seem to paintings, yet fail while it issues such a lot: in construction, lower than heavy load. Java Concurrency in Practice palms readers with either the theoretical underpinnings and urban concepts for development trustworthy, scalable, maintainable concurrent purposes. instead of easily supplying a list of concurrency APIs and mechanisms, it offers layout ideas, styles, and psychological types that enable you to construct concurrent courses which are either right and performant.

This e-book covers:

  • easy options of concurrency and thread protection
  • Techniques for construction and composing thread-safe sessions
  • Using the concurrency construction blocks in java.util.concurrent
  • Performance optimization dos and don'ts
  • Testing concurrent courses
  • Advanced subject matters similar to atomic variables, nonblocking algorithms, and the Java reminiscence Model

In a contemporary put up at the NetBeans developer web site, one of many middle maintainers saw unmarried category have been patched over 14 instances to fix threading-related difficulties. Dion Almaer, former editor of TheServerSide, lately blogged (after a painful debugging consultation that eventually published a threading malicious program) that the majority Java courses are so rife with concurrency insects that they paintings basically “by accident”. certainly, constructing, trying out and debugging multithreaded courses will be super difficult simply because concurrency insects don't occur themselves predictably. And once they do floor, it's always on the worst attainable time—in creation, less than heavy load. one of many demanding situations of constructing concurrent courses in Java is the mismatch among the concurrency gains provided via the platform and the way builders have to take into consideration concurrency of their courses. The language presents low-level mechanisms akin to synchronization and situation waits, yet those mechanisms has to be used regularly to enforce application-level protocols or guidelines.
