2）. 同理对于服务器端首先对读写操作进行封装，主要是为了每一个客户端预录独立管道：

注意：sendf方法服务器将接收到的消息返回发送

sendother：通过广播的方法将接受到消息发送其他人

为了将消息发送给其他客户端，使用容器将所有的客户端都加入到容器中，通过关键字---客户主机之间映射，将消息发送给指定客户端完成私聊的作用；

2）通过 while循环让服务器一直处在于不断地监听信息的状态，

 1 // 做成广播形式
 2     public void start() throws IOException
 3     {
 4         ServerSocket server=new ServerSocket(9999);
 5         
 6         while(true)
 7         {
 8             Socket socket=server.accept();
 9             
10             MyChanner channer1=new MyChanner(socket);
11             all.add(channer1);//加入容器中同一管理
12             new Thread(channer1).start();
13         }
14     }
