如何在java中通过UDP发送int

import java.net.DatagramPacket;
import java.net.DatagramSocket;
import java.net.InetAddress;

public class UDPSender {
    public static void main(String[] args) {
        try {
            int value = 123; // 要发送的int值

            // 将int值转换为字节数组
            byte[] data = new byte[4];
            data[0] = (byte) (value >> 24);
            data[1] = (byte) (value >> 16);
            data[2] = (byte) (value >> 8);
            data[3] = (byte) value;

            // 创建DatagramSocket对象
            DatagramSocket socket = new DatagramSocket();

            // 创建DatagramPacket对象，指定目标IP地址和端口号
            InetAddress address = InetAddress.getByName("目标IP地址");
            int port = 12345; // 目标端口号
            DatagramPacket packet = new DatagramPacket(data, data.length, address, port);

            // 发送DatagramPacket
            socket.send(packet);

            // 关闭DatagramSocket
            socket.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
