Java 范例 - 线程挂起
将线程挂起
public class SleepingThread extends Thread { private int countDown = 5; private static int threadCount = 0; public SleepingThread() { super("" + ++threadCount); start(); } public String toString() { return "#" + getName() + ": " + countDown; } public void run() { while (true) { System.out.println(this); if (--countDown == 0) return; try { sleep(100); } catch (InterruptedException e) { throw new RuntimeException(e); } } } public static void main(String[] args) throws InterruptedException { for (int i = 0; i < 5; i++) new SleepingThread().join(); System.out.println("线程已被挂起"); } }
编译运行以上 Java 代码,输出结果如下
#1: 5 #1: 4 #1: 3 #1: 2 #1: 1 …… #5: 3 #5: 2 #5: 1 线程已被挂起
