java网络编程聊天室

Java网络编程聊天室是一种基于Java语言实现的网络聊天室，可以让多个用户在同一时间内进行在线聊天。下面是一个简单的Java网络编程聊天室的实现过程：

1. 创建服务器端

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

public class Server {
    public static void main(String[] args) throws IOException {
        ServerSocket serverSocket = new ServerSocket(8888);
        System.out.println("服务器已启动，等待客户端连接...");

        while (true) {
            Socket socket = serverSocket.accept();
            System.out.println("客户端已连接：" + socket.getInetAddress().getHostAddress());

            BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            String msg;
            while ((msg = br.readLine()) != null) {
                System.out.println("客户端说：" + msg);
            }
        }
    }
}

2. 创建客户端

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

public class Client {
    public static void main(String[] args) throws IOException {
        Socket socket = new Socket("localhost", 8888);
        System.out.println("已连接服务器...");

        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        PrintWriter pw = new PrintWriter(new OutputStreamWriter(socket.getOutputStream()), true);

        String msg;
        while ((msg = br.readLine()) != null) {
            pw.println(msg);
        }
    }
}

3. 运行程序

首先运行服务器端程序，然后运行多个客户端程序，客户端程序可以在控制台输入聊天内容，服务器端程序会将聊天内容输出到控制台。
