Product Author Bios

Doug Lea is one of the foremost experts on object-oriented technology and software reuse. He has been doing collaborative research with Sun Labs for more than five years. Lea is Professor of Computer Science at SUNY Oswego, Co-director of the Software Engineering Lab at the New York Center for Advanced Technology in Computer Applications, and Adjunct Professor of Electrical and Computer Engineering at Syracuse University. In addition, he co-authored the book, Object-Oriented System Development (Addison-Wesley, 1993). He received his B.A., M.A., and Ph.D. from the University of New Hampshire.



In this second edition, you will find thoroughly updated coverage of the Javao 2 platform and new or expanded coverage of:

  • Memory model
  • Cancellation
  • Portable parallel programming
  • Utility classes for concurrency control

The Java platform provides a broad and powerful set of APIs, tools, and technologies. One of its most powerful capabilities is the built-in support for threads. This makes concurrent programming an attractive yet challenging option for programmers using the Java programming language.

This book shows readers how to use the Java platform's threading model more precisely by helping them to understand the patterns and tradeoffs associated with concurrent programming.

You will learn how to initiate, control, and coordinate concurrent activities using the class java.lang.Thread, the keywords synchronized and volatile, and the methods wait, notify, and notifyAll. In addition, you will find detailed coverage of all aspects of concurrent programming, including such topics as confinement and synchronization, deadlocks and conflicts, state-dependent action control, asynchronous message passing and control flow, coordinated interaction, and structuring web-based and computational services.

The book targets intermediate to advanced programmers interested in mastering the complexities of concurrent programming. Taking a design pattern approach, the book offers standard design techniques for creating and implementing components that solve common concurrent programming challenges. The numerous code examples throughout help clarify the subtleties of the concurrent programming concepts discussed.

5.0 out of 5 stars Excellent, January 30, 2000
This review is from: Concurrent Programming in Java¿: Design Principles and Pattern (2nd Edition) (Paperback)
Simply a great book on concurrent programming in Java. This book and the class library the author provides are an awesome combination. While some of the information is Java specific, this book is much more about concurrent programming in general.

The author explains the primitive concurrency mechanisms provided in Java, such as Threads and Monitors, and then quickly moves on to higher level abstractions that embody many of the patterns found in multi-threaded applications. By encapsulating these, sometimes complex, patterns in reusable classes, the author shows how to maintain the separation of concerns between the concurrent aspects of the code and the logic of the task at hand.

This book contains a thorough discussion of the topic and extensive code - both examples and a reusable class library. This is a must read for every Java developer.

5.0 out of 5 stars Everything you need to know about concurrency in Java, April 11, 2003

This review is from: Concurrent Programming in Java¿: Design Principles and Pattern (2nd Edition) (Paperback)
Concurrent programming is fraught with peril. It's much more complex than sequential programming in every meaningful way from specification to unit testing. But if you want to do it right, meaning balancing liveness with safety for efficient and robust multi-threaded applications, you need Doug Lea's "Concurrent Programming in Java". Especially if you need to design an extensible framework with concurrency; well-known examples of such frameworks incluce Swing, most of java.net, and just about every aspect of J2EE.

Lea provides an intense introduction at the level of an advanced undergraduate course. It's fairly academic in tone, because he takes the time to provide thorough definitions and detailed examples. As a former academic who now designs and programs for a living, this is just what I was looking for. But don't buy this book expecting a cookbook of code to cut and paste. It's much more about providing you the fundamental tools to design your own concurrent... Read more

(REAL NAME)   
This review is from: Concurrent Programming in Java¿: Design Principles and Pattern (2nd Edition) (Paperback)
The book is a valuable resource for experienced programmers who are trying to write large, complex, real-life concurrent Java programs. The book discusses in depth many concurrency-specific issues you can run into, especially with Java. It gives tons of useful advice (in rather abstract form), both in text and in code (see the book's website for more complete examples). The book is full of useful frameworks and patterns.

However, it make take you a while to understand most of them. The author is fairly careless about the reader, and lets the reader do all the work. To understand one paragraph you may have to browse through 10 other pages, because that parargraph would reference them directly or indirectly. For example, to understand what is meant by "volatile" or "ThreadLocal", it helps to read several pages that precede these terms (and in other instances, you'd have to read several pages that follow). In other words, the book is not easily digestible, and many sections have to be... Read more
