Beginner question - the differences between .h and .m

Hi, I have just started learning Cocoa and I have been reading the apple
tutorials but one thing they don't really explain is what is the purpose of
a .m and .h for each class. This is probably a silly question but coming
from a java im only used to seeing one class file.

Happy Easter

Thanks
Alex
