Is it necessary to create the newAmount variable?

The same was accomplished if I replaced newAmount=mPezCount+pezAmount with mPezCount=+pezAmount;

Is that a valid way to go about it or will I run into problems eventually?

I have two answers for you that may seem contradictory:

  1. Yes, that is a valid way to it. There is often more than one way to program something. Sometimes a problem is better suited to one solution then another, other times it's more which style you're comfortable with.

  2. Yes, you will get into trouble later doing it that way. As I recall, you'll also be checking to see if you'd be overfilling the dispenser. It helps in that case to check the amount first before storing it.
