join是Thread类的一个方法,启动线程后直接调用,例如: 1 Thread t = new AThread(); t.start(); t.join(); 1. 二、为什么要用join()方法 在很多情况下,主线程生成并起动了子线程,如果子线程里要进行大量的耗时的运算,主线程往往将于子线程之前结束,但是如果主线程处理完其他的事务后,需要用到子线程的处...
关于Thread中的join方法貌似在实际多线程编程当中没怎么用过,在当初学j2se的时候倒时去学习过它的用法,不过现在早已经忘得差不多啦,所以对它再复习复习下。 首先先观察下JDK对它的介绍: 其实就是等待一个线程结束,对它记忆中还是有印象的,下面实践一下: ...
可见,fork()操作是通过调用ForkJoinWorkerThread.pushTask()实现的。该方法在上面已做分析,不再赘述。 join方法的主要作用是阻塞当前线程并等待获取结果。代码如下: /** * Returns the result of the computation when it {@link #isDone is * done}. This method differs from {@link #get()} in that *...
