1.7.6方法stop()与java.lang.threadDeath异常

调用stop方法时会抛出java.lang.ThreadDeath异常，但一般情况下这个异常不需要显示的捕捉

package com.cky.thread;

/**
 * Created by edison on 2017/12/3.
 */
public class MyThread extends Thread{
    @Override
    public void run() {
        super.run();
        try {
           this.stop();
        } catch (ThreadDeath e) {
            e.printStackTrace();
        }
    }
}

package com.cky.test;

import com.cky.thread.MyThread;

/**
 * Created by edison on 2017/12/3.
 */
public class Test {
    public static void main(String[] args) {
            MyThread th = new MyThread();
            th.start();
    }
}

方法stop已经作废

因为如果强制让线程停止则会使得一些清理性的工作得不到完成，另外一个就是对锁定对象进行解锁，导致数据得不到同步处理，出现数据不一致。
