Java Java Objects Harnessing the Power of Objects Incrementing and Decrementing

why are we decrementing the dispenser with "--" instead of just doing "-="?

because the teacher said that doing "--" returns what the value 'used to be' and then it increments -- why do we need to do that if we are taking PEZ out. wouldn't it make more sense to simply minus 1 each time with a "-="?

As used here, the return value is ignored so there's no functional difference between pezCount -= 1 and
pezCount--. The choice of the latter is probably only due to the fact that it takes up less space in the code.

thank you so much!
