Java进行并发多连接socket编程

 Java多个客户端同时连接服务端，在现实生活中用得比较多。同时执行多项任务，第一想到的当然是多线程了。下面用多线程来实现并发多连接。

import java.net.*; import java.io.*; public class ThreadServer extends Thread {     private Socket client;     public ThreadServer(Socket c)     {         this.client=c;     }     public void run()     {         try         {             BufferedReader in=new BufferedReader(new InputStreamReader(client.getInputStream()));             PrintWriter out=new PrintWriter(client.getOutputStream());             //Mutil User but can't parallel             while (true)             {                 String str=in.readLine();                 System.out.println(str);                 out.println("has receive....");                 out.flush();                 if (str.equals("end"))                     break;             }             client.close();         }         catch (IOException ex)         {         }         finally         {         }     }     public static void main(String[] args)throws IOException     {         ServerSocket server=new ServerSocket(8000);         while (true)         {             //transfer location change Single User or Multi User             ThreadServer mu=new ThreadServer(server.accept());             mu.start();         }     } }

一家之言，请多指教！
