The "Concurrent" prefix used with some classes in this package is a shorthand indicating several differences from similar "synchronized" classes. For examplejava.util.HashtableandCollections.synchronizedMap(new HashMap())are synchronized. ButConcurrentHashMapis "concurrent". A concurrent collection is th...
To address this problem, Java 5 [11] introduced the new java.util.concurrent (j.u.c.) package for writing concurrent programs. The classes in the j.u.c.Atomic package provide thread-safe and lock-free primitives to control individual variables. Its collection classes are optimized for ...

JAVA并发下载 java并发包concurrent 一、包的结构层次 其中包含了两个子包atomic和locks,另外字concurrent下的阻塞队列以及executor,这些就是concurrent包中的精华。而这些类的实现主要是依赖于volatile和CAS,从整体上看concurrent包的整体实现图如下: 二、Lock和synchronized的比较...
The new mechanisms are part of the java.util.concurrent package, which aims to offer a standard set of concurrency utilities that will ease the task of developing multithreaded applications and servers. In addition, such standards will improve the quality of such applications. The package has been...
