java基于TCP的C/S通信，客户端和服务器端一对一对话，服务器端的UI窗口设置监听按钮，以及将发送和收到的消息显示在两个框内

以下是一个简单的Java基于TCP的C/S通信的客户端和服务器端一对一对话的代码示例：

服务器端代码：

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

public class Server {
    public static void main(String[] args) {
        try {
            ServerSocket serverSocket = new ServerSocket(8080);
            System.out.println("Server started.");

            while (true) {
                Socket socket = serverSocket.accept();
                System.out.println("Client connected.");

                BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
                PrintWriter out = new PrintWriter(new OutputStreamWriter(socket.getOutputStream()), true);

                String message;
                while ((message = in.readLine()) != null) {
                    System.out.println("Received message: " + message);
                    out.println("Server: " + message);
                }

                in.close();
                out.close();
                socket.close();
                System.out.println("Client disconnected.");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

客户端代码：

import java.io.*;
import java.net.*;
import javax.swing.*;

public class Client {
    public static void main(String[] args) {
        try {
            Socket socket = new Socket("localhost", 8080);
            System.out.println("Connected to server.");

            BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            PrintWriter out = new PrintWriter(new OutputStreamWriter(socket.getOutputStream()), true);

            JFrame frame = new JFrame("Client");
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setSize(400, 300);

            JTextArea receivedArea = new JTextArea();
            receivedArea.setEditable(false);
            JScrollPane receivedScrollPane = new JScrollPane(receivedArea);
            receivedScrollPane.setSize(300, 100);
            receivedScrollPane.setLocation(50, 50);
            frame.getContentPane().add(receivedScrollPane);

            JTextArea sendArea = new JTextArea();
            JScrollPane sendScrollPane = new JScrollPane(sendArea);
            sendScrollPane.setSize(300, 100);
            sendScrollPane.setLocation(50, 170);
            frame.getContentPane().add(sendScrollPane);

            JButton sendButton = new JButton("Send");
            sendButton.setSize(70, 30);
            sendButton.setLocation(280, 280);
            sendButton.addActionListener(e -> {
                String message = sendArea.getText();
                out.println(message);
                receivedArea.append("Client: " + message + "\n");
                sendArea.setText("");
            });
            frame.getContentPane().add(sendButton);

            frame.setVisible(true);

            String message;
            while ((message = in.readLine()) != null) {
                receivedArea.append(message + "\n");
            }

            in.close();
            out.close();
            socket.close();
            System.out.println("Disconnected from server.");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

服务器端的UI窗口设置监听按钮以及将发送和收到的消息显示在两个框内，可以参考客户端代码的实现方式。
