java中给出一个多线程TCP的ServerSocket例子？

以下的例子，是一个服务器对多个客户端。我们的客户端程序可以运行很多遍，代表多个客户。 　 /*in this frame work, many clients can access the server with many thread and many socket using only one port,
bbb client use bbb socket with bbb thread, by default, one port can accept 50 socket. */


import java.net.ServerSocket;
import java.io.*;
import java.net.Socket;
