<p>Can you provide an example of a byte buffer transferred between two java classes via UDP datagram?</p>

Hows' this ?
```
import java.io.IOException;
import java.net.DatagramPacket;
import java.net.DatagramSocket;
import java.net.InetSocketAddress;

public class Server {

    public static void main(String[] args) throws IOException {
        DatagramSocket socket = new DatagramSocket(new InetSocketAddress(5000));
        byte[] message = new byte[512];
        DatagramPacket packet = new DatagramPacket(message, message.length);
        socket.receive(packet);
        System.out.println(new String(packet.getData(), packet.getOffset(), packet.getLength()));
    }
}
```
```
import java.io.IOException;
import java.net.DatagramPacket;
import java.net.DatagramSocket;
import java.net.InetSocketAddress;

public class Client {

    public static void main(String[] args) throws IOException {
        DatagramSocket socket = new DatagramSocket();
        socket.connect(new InetSocketAddress(5000));
        byte[] message = "Oh Hai!".getBytes();
        DatagramPacket packet = new DatagramPacket(message, message.length);
        socket.send(packet);
    }
}
```
