在Java网络编程中，socket连接断开是一个常见的问题。以下是一个简单的案例：

案例：TCP客户端与服务器的通信

客户端代码（Client.java）:

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())))) {
            System.out.println("Connected to server...");
            // 发送消息
            String message = "Hello, Server!";
            in.write(message.getBytes());
            // 接收并打印服务器响应
            String response = in.readLine();
            System.out.println("Server Response: " + response);
        } catch (IOException e) {
            e.printStackTrace();
            System.out.println("Connection failed.");
        }
    }
}

服务器代码（Server.java）:

import java.io.*;
import java.net.*;
public class Server {
    public static void main(String[] args) throws IOException {
        ServerSocket serverSocket = new ServerSocket(1234);
        System.out.println("Server started listening on port 1234...");
        while (true) {
            Socket socket = serverSocket.accept();
            Thread thread = new Thread(() -> handleClient(socket)));
            thread.start();
        }
    }
    private static void handleClient(Socket socket) throws IOException {
        BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream())));
        System.out.println("New client connected...");
        // 接收客户端发送的消息
        String message = in.readLine();
        System.out.println("Received message from client: " + message);
        // 发送服务器响应
        String response = "Server received your message. Thanks!";
        in.write(response.getBytes());
        in.close();
        socket.close();
    }
}
