12,938 PointsYou've got to remember that the while loop will execute until its statement is false. Dispense() is a method which returns a boolean false when the PezDispenser is empty. If it is full, a Pez is dispensed and the method returns true, so the while loop will keep going. I don't remember off the top of my head, but earlier in the code the Pez Dispenser is probably loaded with 12 candies. Thus, dispense will return true 12 times and you'll see Chomp! printed to the screen each time.

12,938 PointsBecause the number of pez in the PezDispenser is stored in a member variable, and the while loop in dispense will execute as long as that member variable is nonzero (so if you have 12 candies, the while loop executes 12 times).
