Examples of java.net.MulticastSocket.joinGroup()

java.net.MulticastSocket.joinGroup()
Joins a multicast group. Its behavior may be affected by setInterface or setNetworkInterface.
If there is a security manager, this method first calls its checkMulticast method with the mcastaddr argument as its argument. @param mcastaddr is the multicast address to join @exception IOException if there is an error joiningor when the address is not a multicast address. @exception SecurityException if a security manager exists and its checkMulticast method doesn't allow the join. @see SecurityManager#checkMulticast(InetAddress)
