除了能够使用 fork/join 框架来实现能够在多处理系统中被并行执行的定制化算法(如前文中的 ForkBlur.java 例子),在 Java SE 中一些比较常用的功能点也已经使用 fork/join 框架来实现了。在 Java SE 8 中,java.util.Arrays 类的一系列parallelSort() 方法就使用了 fork/join 来实现。这些方法与 sort() 方法很...

Here is a simple example of CyclicBarrier in Java on which we initialize CyclicBarrier with 3 parties, means in order to cross barrier, 3 thread needs to call await() method. each thread calls await method in short duration but they don’t proceed until all 3 threads reached barrier, once...
SimpleThreads 示例,有两个线程,第一个线程是每个 Java 应用程序都有主线程。主线程创建的 Runnable 对象 MessageLoop,并等待它完成。如果 MessageLoop 需要很长时间才能完成,主线程就中断它。 该MessageLoop 线程打印出一系列消息。如果中断之前就已经打印了所有消息,则 MessageLoop 线程打印一条消息并退出。 public ...
