Java 實(shí)例 - 線程掛起
以下實(shí)例演示了如何將線程掛起:
/* author by w3cschool.cn SleepingThread.java */ 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("線程已被掛起"); } }
以上代碼運(yùn)行輸出結(jié)果為:
#1: 5 #1: 4 #1: 3 #1: 2 #1: 1 …… #5: 3 #5: 2 #5: 1 線程已被掛起
