UDP协议的发送端的基本代码

public class SendDemo {public static void main(String[] args) throws IOException {// 创建发送端的Socket对象DatagramSocket ds = new DatagramSocket();// 创建数据并打包byte[] bys = "helloworld".getBytes();DatagramPacket dp = new DatagramPacket(bys, bys.length,InetAddress.getByName("192.168.12.92"), 12345);// 发送数据ds.send(dp);// 释放资源ds.close();}}
