Next, a server class can be used to broadcast datagrams to the address that multicast
clients are connected to. The following code demonstrates a multicast server:

package org.java8recipes.chapter21.recipe21_4;

import java.io.IOException;
import java.net.InetAddress;
import java.net.InetSocketAddress;
import java.nio.ByteBuffer;
import java.nio.channels.DatagramChannel;

public class MulticastServer extends Thread {

protected ByteBuffer message = null;

public MulticastServer() {
}
