关于Java网络编程：socket连接异常案例

在Java的网络编程中，Socket连接可能会出现各种异常。以下是一个具体的Socket连接异常案例：

import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.Socket;
public class SocketExceptionExample {
    public static void main(String[] args) {
        // 创建一个Socket对象
        try (Socket socket = new Socket("localhost", 1234)) {
            // 连接成功，打印消息
            System.out.println("Socket connected successfully!");
            // 发送数据
            byte[] message = "Hello, Server!".getBytes();
            socket.getOutputStream().write(message);
            // 接收数据
            byte[] receivedData = new byte[1024];
            int lengthReceived = socket.getInputStream().read(receivedData));
            String dataReceived = new String(receivedData, 0, lengthReceived));
            // 打印接收的数据
            System.out.println("Received Data: " + dataReceived);
        } catch (IOException e) {
            // 处理连接异常
            System.err.println("Socket connection failed with error: " + e.getMessage());
            e.printStackTrace();
        }
    }
}
