网络编程：JavaSocket通信问题案例

在Java编程中，Socket是一种用于在网络上进行双向通信的API。以下是一个简单的Socket通信问题案例：

客户端（发送方）代码：

import java.io.*;
import java.net.*;
public class Client {
    public static void main(String[] args) {
        try {
            // 创建连接
            Socket socket = new Socket("localhost", 1234); // 地址为localhost，端口为1234
            // 获取输出流
            PrintWriter writer = new PrintWriter(socket.getOutputStream(), true));
            // 发送数据
            writer.println("Hello from Client!");
            // 关闭资源
            writer.close();
            socket.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

服务器端（接收方）代码：

import java.io.*;
import java.net.*;
public class Server {
    public static void main(String[] args) throws IOException {
        ServerSocket server = new ServerSocket(1234); // 端口为1234
        System.out.println("Server is listening...");
        Socket client = server.accept(); // 接受客户端连接
        BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()))); // 从客户端接收数据
        PrintWriter writer = new PrintWriter(client.getOutputStream(), true)); // 向客户端发送数据
        String message;
        while ((message = in.readLine()) != null) {
            System.out.println("Received from Client: " + message);
            writer.println("Server received the message. Sending acknowledgement back to client.");
        }
        writer.close();
        in.close();
        client.close();
        server.close();
    }
}
