class DatagramPacketDemo {

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

      // create a DatagramSocket object
      DatagramSocket ds = new DatagramSocket();

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

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

      // create a int object iport and assign value to it
      int iport = 9999;

      // set the port number for datagram dp
      dp.setPort(iport);

      String str = "Data being sent using port number : " + iport;

      System.out.println( str );
