用while循环可以让多个客户端可以连接服务器

while(true){

//主线程等待客户端发起连接

Socket s = ss.accept(端口);

//每个网络连接操作由工作线程进行操作、通信

WorkThread t= new WorkThread(s);

t.start();

}

class WorkThread{

public WorkThread(Socket s){

        this.s = s;

    }

run(Socket s){

BufferedReader in = new BufferedReader(

new InputStreamReader(s.getInputStream()));

PrintWriter out = new PrintWriter(s.getOutputStream());

}

}
