一、Thread.stop()

官方不推荐，Because it is inherently unsafe.

二、方式一

1. 线程类示例

public class ThreadT1 implements Runnable {    private Thread threadThis;    public void start() {        threadThis = new Thread(this);        threadThis.start();    }    public void stop() {        threadThis = null;    }    public void run() {        Thread thisThread = Thread.currentThread();        while (threadThis == thisThread) {        System.out.println("lalala~ ");        // DO YOUR WORK !    }    System.out.println("stopped!!!");    }}

2. 使用示例

ThreadT1 th1 = new ThreadT1();th1.start(); //新建线程并启动th1.stop(); //停止这个线程

三、方式二

1. 线程类示例

public class ThreadT2 extends Thread {    private boolean stop = false;    public void stopByMark() {        stop = true;    }    public void run() {        while (!stop) {        System.out.println("lalala~ ");        // DO YOUR WORK !    }    System.out.println("stopped!!!");    }}

2.使用示例

ThreadT2 th2 = new ThreadT2();th2.start(); //新建线程并启动th2.stopByMark(); //停止这个线程

附、关于Thread.interrupt()

通过这个方式也能停止线程。

前提条件：

public void run(){    try {        Thread.sleep(5000);    } catch (InterruptedException e) { //必须存在捕获InterruptedException的方法，且发生了该    抛出就调用stop方法。    e.printStackTrace();    stopByMark();    }}
