Java网络编程：TCP连接建立与关闭示例

在Java中，我们可以使用java.net包中的Socket和ServerSocket类来实现TCP连接的建立与关闭。以下是一个简单的示例：

客户端建立连接：

import java.io.*;
import java.net.*;
public class Client {
    public static void main(String[] args) {
        try (Socket socket = new Socket("localhost", 1234))) {
            BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream())));
            PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
            // 发送数据
            out.println("Hello, Server!");
            // 接收数据
            String response = in.readLine();
            System.out.println("Server's Response: " + response);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

服务器接收并回应客户端：

import java.io.*;
import java.net.*;
public class Server {
    public static void main(String[] args) {
        try (ServerSocket serverSocket = new ServerSocket(1234));) {
            Socket socket = serverSocket.accept();
            BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream())));
            PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
            // 接收客户端消息
            String clientMessage = in.readLine();
            System.out.println("Received message from client: " + clientMessage);
            // 发送回应给客户端
            out.println("Hello, Client! Your message received.");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
