DatagramSocket.receive() error

[iamgoodatthis]

Hello. I'm getting an unexpected NullPointerException when using the receive method from DatagramSocket. Here is my code:

DatagramPacket waiting = null;
try
{
DatagramSocket socketReceive = new DatagramSocket(100);
socketReceive.receive(waiting);
}
catch(IOException e)
{
}

The exact error is NullPointerException in DatagramSocket, receive method line 647. All help would be appreciated.

Thanks.

A NullPointerExpression means that you are referencing a null object. If this is all the code you have, waiting is null and cannot be sent as a DatagramPacket.

P.S.
I have no idea what DatagramSockets or DatagramPackets are, anyway.
