具体描述
Concurrency on the Java platform has evolved, from the synchronization model of JDK to software transactional memory (STM) and actor-based concurrency. This book is the first to show you all these concurrency styles so you can compare and choose what works best for your applications. You’ll learn the benefits of each of these models, when and how to use them, and what their limitations are.
Through hands-on exercises, you’ll learn how to avoid shared mutable state and how to write good, elegant, explicit synchronization-free programs so you can create easy and safe concurrent applications. The techniques you learn in this book will take you from dreading concurrency to mastering and enjoying it. Best of all, you can work with Java or a JVM language of your choice – Clojure, JRuby, Groovy, or Scala – to reap the growing power of multicore hardware.
If you are a Java programmer, you’d need JDK 1.5 or later and the Akka 1.0 library. In addition, if you program in Scala, Clojure, Groovy or JRuby you’d need the latest version of your preferred language. Groovy programmers will also need GPars.

评分书中讲到了并发编程的本质问题，说明了synchronized的低效，并推荐使用jdk1.5新api编程; 并详细介绍了STM和角色两种现代解决方案，STM类似于数据库的并发技术， 而角色则完全隔离了“共享可变性”， 这两钟技术都避免使用“低效的锁”；
用户评价
以后有时间再读第2遍吧。例子仍然比较基础。
评分介绍了 JVM 语言中并发的模式与利弊，这对开拓眼界是非常有用的，书中给出的算文件夹大小的例子也不错，由浅入深，逐步完善。
评分作者提出了3个并发模型，shared mutability, isolated mutability, immutability,shared就是我们java里边经常使用的，对于这个模型，可以通过STM提高其并发度，但是STM也有其劣势，比如说在大量的修改面前，会疯狂的消耗cpu，isolated mutability比较好，就是actor模型，但是对于消息通信的actor需要注意粒度的问题，actor必须是粗粒度的，如果是细粒度的话，会导致大量的消息传递，以及上下文切换，导致performance的下降。最后的web resources和参考书目是非常好的阅读知道，可以看一些其他方面的知识来提高对并发的理解和设计。一句话monitor的单核时代已经过去了，拥抱多核时代，拥抱不变试。
评分recommended by groups of taobao.
评分STM, actor model, 扩展扩展视野还不错，就是通篇都是toy example有点受不了
