这篇教程Java 实例 - 状态监测写得很实用，希望能帮到您。
以下实例演示了如何通过继承 Thread 类并使用 currentThread.getName() 方法来监测线程的状态： Main.java 文件 class MyThread extends Thread{ boolean waiting= true; boolean ready= false; MyThread() { } public void run() { String thrdName = Thread.currentThread().getName(); System.out.println(thrdName + " starting."); while(waiting) System.out.println("waiting:"+waiting); System.out.println("waiting..."); startWait(); try { Thread.sleep(1000); } catch(Exception exc) { System.out.println(thrdName + " interrupted."); } System.out.println(thrdName + " terminating."); } synchronized void startWait() { try { while(!ready) wait(); } catch(InterruptedException exc) { System.out.println("wait() interrupted"); } } synchronized void notice() { ready = true; notify(); }}public class Main { public static void main(String args[]) throws Exception{ MyThread thrd = new MyThread(); thrd.setName("MyThread #1"); showThreadStatus(thrd); thrd.start(); Thread.sleep(50); showThreadStatus(thrd); thrd.waiting = false; Thread.sleep(50); showThreadStatus(thrd); thrd.notice(); Thread.sleep(50); showThreadStatus(thrd); while(thrd.isAlive()) System.out.println("alive"); showThreadStatus(thrd); } static void showThreadStatus(Thread thrd) { System.out.println(thrd.getName() + "Alive:=" + thrd.isAlive() + " State:=" + thrd.getState()); }} 以上代码运行输出结果为： ……alivealiveMyThread #1 terminating.alive……
