请教一个关于socket的问题

Question

当然可以散！
ServerSocket listener=new ServerSocket(port);
Socket linksocket=listener.accept();
try{
  PrintStream out=new PrintStream(
                           new BufferedOutputStream(
                               linksocket.getOutputStream()));
  out.println("hello,this is server!!!")
  out.flush();
  ...............
}catch(...............)

Answer 1

当然可以，就想客户端给服务器端发送信息差不多，通过Socket得到输入输出流，在进行通讯

Answer 2

连接是双向的，当然可以了。
简单实例代码：客户端和服务器端建立连接并发送本机名。
客户端：
    try{
      connection=new Socket("localhost",2568);      BufferedReader input=new BufferedReader
          (new InputStreamReader(connection.getInputStream()));
      PrintWriter output=new PrintWriter
          (new BufferedWriter
           (new OutputStreamWriter(connection.getOutputStream())),true);      String cli=InetAddress.getLocalHost().toString();
      output.println(cli);      String str=input.readLine();
      jTextField1.setText(str);
    }
    catch (IOException ie) {
    }
服务器端：
    try {
      server = new ServerSocket(2568);
      connection = server.accept();      BufferedReader input=new BufferedReader
          (new InputStreamReader(connection.getInputStream()));
      PrintWriter output=new PrintWriter
          (new BufferedWriter
           (new OutputStreamWriter(connection.getOutputStream())),true);      String ser=InetAddress.getLocalHost().toString();
      output.println(ser);      String cli=input.readLine();
      jTextField1.setText(cli);
    }
    catch (IOException ie) {
    }

Answer 3

建立连接之后，socket是对等的双向连接，两端节点是平等的。

Answer 4

我想实现这样一个功能：就是两边连通，A给B发条消息，然后B回复A收到，哪位老大能给一段代码呀！！！！！！！！
