I'm just in the process of finishing off the last little bit of my Java coursework ready for tomorrow...

Trouble is, I need to implement a little popup box alerting the user that they have not filled in all the fields. I know its a simple one liner, but Ive just had a complete mental block and not even google is helping me :/
