How to send to receive datagram packet?

DatagramSocket s = new DatagramSocket(null);
s.bind(new InetSocketAddress(8888));

Which is equivalent to:
DatagramSocket s = new DatagramSocket(8888);

Both cases will create a DatagramSocket able to receive broadcasts on UDP port 8888.

One can create a packet as:
DatagramPacket packet = new DatagramPacket(message, message.length, address, DAYTIME_PORT);

To send or receive a packet, the sockets send or receive methods can be used:
