java concurrency in practice book

outstanding open source Concurrency Toolkit, java.util.concurrent, which contains mutex, trust, and performance-performing collection classes such as queues and hash tables, and some work queue implementations under concurrent access. The Pooledexecutor class in this package is an efficient, widely used, and correct implementation of a thread pool based on a work queue. Instead of trying to write the code yourself, it's easy to make mistakes, and you

cases provides better performance and scalability than locks. If you strictly follow the use of volatile conditions-that is, the variable is really independent of the other variables and its own previous values-in some cases you can use the volatile substitution synchronized to simplify the code. However, volatile the code used is often more error-prone than code that uses locks. The pattern described in this article covers some of the most common use cases that can be used volatile instead syn

Singleton mode is one of the most common and important design patterns in Java design patterns.The simplest notation is: Public classTestsingleton {Private StaticString ourinstance =NULL; //Privatization Constructor PrivateTestsingleton () {}//provides static methods for external access Public StaticString getourinstance () {if(Ourinstance = =NULL) {ourinstance= "Singleton mode assignment succeeded!!!" "; System.out.print (ourinstance);

Popular Atoms: Introduced the new atomic variable class in Java 5.0. This feature extends the volatile variable to support atomic state conversion. Introduction to non-Blocking Algorithms: Describes how to use atomic variables instead of locks to implement concurrent algorithms. Volatiles: Get mo

I always wanted to learn Java because of curiosity and free. But because it is not used at work, and it is too high in hardware configuration, it is only occasionally used to learn. I have found tutorials and articles on the Internet, but I have not learned anything. I also bought more than 700 pages of Java j2se 5 edition reference book, because it is too thick

The Java language provides flexible, seemingly simple threading capabilities that make it easy to use multithreading in your applications. However, concurrent programming in Java applications is more complex than it seems: in Java programs, there are subtle (and perhaps not subtle) ways to create data contention (race) and co
