给我写一个Java实现TCP聊天的案例

如题

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

public class TCPServer {
    public static void main(String[] args) {
        try {
            ServerSocket serverSocket = new ServerSocket(9999);
            System.out.println("服务器启动，等待客户端连接...");

            Socket socket = serverSocket.accept();
            System.out.println("客户端已连接");

            BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            PrintWriter writer = new PrintWriter(socket.getOutputStream(), true);

            BufferedReader consoleReader = new BufferedReader(new InputStreamReader(System.in));

            String input, output;
            while (true) {
                input = reader.readLine();
                System.out.println("客户端: " + input);
                
                if (input.equalsIgnoreCase("exit")) {
                    break;
                }

                System.out.print("请输入回复消息: ");
                output = consoleReader.readLine();
                writer.println(output);

                if (output.equalsIgnoreCase("exit")) {
                    break;
                }
            }

            socket.close();
            serverSocket.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

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

public class TCPClient {
    public static void main(String[] args) {
        try {
            Socket socket = new Socket("localhost", 9999);

            BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            PrintWriter writer = new PrintWriter(socket.getOutputStream(), true);

            BufferedReader consoleReader = new BufferedReader(new InputStreamReader(System.in));

            String input, output;
            while (true) {
                System.out.print("请输入消息: ");
                output = consoleReader.readLine();
                writer.println(output);

                if (output.equalsIgnoreCase("exit")) {
                    break;
                }

                input = reader.readLine();
                System.out.println("服务器: " + input);

                if (input.equalsIgnoreCase("exit")) {
                    break;
                }
            }

            socket.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

这里提供了一个简单的TCP聊天案例，包括服务端和客户端的代码。你可以分别运行这两个程序，服务端监听9999端口，客户端连接到该端口，然后实现简单的信息传递。当输入"exit"时，程序将退出。希望对你有帮助！
