This is illogical: if(!dispenser.isEmpty()) System.out.println("Dispenser is full");

The dispenser may not be empty, but it may not be full either. The output should be "Dispenser is not empty"

Depending on how far you are through the course you may not have got to the part of the course yet that is specific on how many Pez are in the dispenser.

At the moment (If I'm right) all you're concerned about is two states in the method. Is the dispenser full of Pez or is it completely empty. If you add the !, which is the negation operator you checking for a dispenser with Pez.
