终止线程-stop

          
package com.infuq;
import java.net.*;
import java.io.*;

public class StopThread {
    public static void main(String[] args) throws Exception {

        Thread t = new Thread() {
            @Override
            public void run() {
                try {
                    Socket client = new Socket("127.0.0.1", 8080);
                    while (true) {
                        System.out.println("child thread....");
                    }
                } catch (Throwable t) {
                    System.out.println(t);
                }
            }
        };
        t.start();

        Thread.sleep(3000);
        // 终止线程
        t.stop();
    }
}
          
        

使用Python启动一个服务端

          
python3 -m http.server 8080
          
        

编译和执行StopThread

          
javac -d . StopThread.java
java com.infuq.StopThread
          
        

控制台输出

          
child thread....
child thread....
child thread....
child thread....
child thread....
child thread....
child thread....
child thread....
child thread....

java.lang.ThreadDeath
          
        

网络连接情况

          
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      1505/python3

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

调用stop方法, 需要注意线程持有的锁资源和网络资源等
