一.join() Thread中的join()方法就是同步,它使得线程之间由并行执行变为串行执行. public class MyJoinTest { public static void main(String[] args) { Vector<Thread> threadVector = new Vector<Thread>(); for (int i = 0;i<5;i++){ Thread childThread = new Thread(new Runnable()
使用Java多线程编程时经常遇到主线程需要等待子线程执行完成以后才能继续执行,那么接下来介绍一种简单的方式使主线程等待. java.util.concurrent.CountDownLatch 使用countDownLatch.await()方法非常简单的完成主线程的等待: public class ThreadWait { public static void main(String[] args) throws InterruptedException { int threadNumber
方法一: Thread.join()方法,亲测可行,thread.join()方法 Vector<Thread> ts = new Vector<Thread>(); for (int i = 0; i < 200; i++) { Thread t = new Thread(new Runnable() { @Override public void run() { Counter.inc(); } }); ts.add(t); t.start(); } for (Threa
