The following example shows the usage of net.DatagramPacket.getPort() method

package com.tutorialspoint;

import java.net.*;

class DatagramPacketDemo {

   public static void main(String args[]) throws Exception {

      // create a DatagramSocket object binded to port 9999
      DatagramSocket ds = new DatagramSocket(9999);

      // create a byte array buf
      byte buf[] = new byte[100];

      // create a DatagramPacket object
      DatagramPacket dp = new DatagramPacket(buf, buf.length);

      // recieve the datagram packet into dp
      ds.receive(dp);

      // create an int object p, which stores port number
      int p = dp.getPort();

      // print p value
      System.out.println("Port number is : " + p );
   }
}

Let us compile and run the above program, this will produce the following result:

Port number is : 4499
