Music. In General. Will not work.

[Ethan3210]

Our entire Grade 12 programming class is stumped, on the account that noone, including the teacher, can get music working in any form (other than applets, but we aren't using those). No matter what example he gives us, they never work for him, or for any of us. It's becoming so much of a problem that some of our class is switching over to other languages for the sole fact that music is easier to implement.
If anyone can give a good example of how to make a program that plays music, using a JPanel that has three buttons: One that starts music, one that stops it, and one that loops it... I'd be very grateful, along with the entire class.
