import java.util.concurrent.TimeUnit;/** * 6-13 */public class Join { public static void main(String[] args) throws Exception { Thread previous = Thread.currentThread(); for (int i = 0; i < 10; i++) { // 每个线程拥有前一个线程的引用，需要等待前一个线程终止，才能从等待中返回 Thread thread = new Thread(new Domino(previous), String.valueOf(i)); thread.start(); previous = thread; } TimeUnit.SECONDS.sleep(5); System.out.println(Thread.currentThread().getName() + " terminate."); } static class Domino implements Runnable { private Thread thread; public Domino(Thread thread) { this.thread = thread; } public void run() { try { thread.join(); } catch (InterruptedException e) { } System.out.println(Thread.currentThread().getName() + " terminate."); } }} |
