      // 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 InetAddress object ia and assign destination address
      InetAddress ia = InetAddress.getByName("localhost");
