How did the dispense method run without being told to?

Hi Kenneth,

The dispense method is getting called within Example.java. Even though itis just being used to "check" inside the while loop, the function does get called.

So where your code is:

while(dispenser.dispense){
  // do stuff
}

This is calling the dispense method on the instance of the PezDispenser class, dispenser - if the return value of that method/function is true it'll run the code inside the while loop. If the returned value is false, which means the call to isEmpty() was true then the code inside the while block won't run.

But in either scenario, the method was called so it was told to run - in answer to your question!

I do hope that made sense?!!

Steve.
