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.
