join() method ofJava.lang.Threadclass is used to maintain the order of excution of threads. Using join() method can make currently executing thread wait for some other threads finish their tasks. Implemention of

Thread t = new AThread(); t.start(); t.join(); 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理结果,也就是主线程需要等待子线程执行完成之后再结束,这个时...
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...

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 *...
