任何人都可以帮我用swing GUI创建套接字编程吗？ [英] Can any one help me to create socket programming with swing GUI?

问题描述

我已经完成了一个套接字程序，其中多个客户端向server1发送数据，server1将数据转发到server2。现在我想用Swing GUI做这个程序。任何人都可以帮我创建它吗？

我在下面提交我的代码==



我尝试了什么：



客户

I already done a socket program where multiple client send data to server1 and server1 forward the data to server2. Now I want to do this program with Swing GUI. Can anyone help me how to create it?
I submit my code below ==

What I have tried:

Client

import java.net.*;
import java.io.*;


public class JavaClientApp {

    public static void main(String[] args) throws IOException {
        // Setting server hostname 127.0.0.2
        String hostName = "127.0.0.2";
        // Setting server port number 5056
        int portNumber = Integer.parseInt("5056");

        Boolean done = false;
        while (done == false) {
        
               // Instantinate the buffer reader object to read data from stdin
               BufferedReader stdIn =
                   new BufferedReader(new InputStreamReader(System.in));
            
               System.out.print("Type in your message /> ");
           
               // Retrieve each line from user input
               String userInput = stdIn.readLine();
                 
               if (userInput.equals("Quit") || userInput.equals("Exit")) {
                   done = true; break;
               }
                    
               // Print out `Sending a message...` string
               System.out.println("Sending a message...");
                
               Socket clientSocket = new Socket(hostName, portNumber);
                
               BufferedReader inputStream = new BufferedReader(
                       new InputStreamReader(clientSocket.getInputStream()));
                
               PrintWriter outputStream = new PrintWriter(clientSocket.getOutputStream(), true);
                
               outputStream.println(String.format(userInput));

               String msg_buf = inputStream.readLine();
                
               System.out.println(msg_buf);
