More than ever, learning to program concurrency is
critical to creating faster, responsive applications.
Speedy and affordable multicore hardware is driving the
demand for high-performing applications, and you can
leverage the Java platform to bring these applications
to life. 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. |
