why was the boolean wasDispensed not declared outside of the dispense() method??? in other methods like isEmpty() and load(), the mPezCount is declared outside. Can someone please clarify this for me. Thanks in advance

method it is best to declare it as a local variable, inside the method. Knowing whether one pez was dispensed or not has more to do with the act of dispensing a pez, hence used inside the dispense method, than the pez dispenser in general. On the other hand, the value of mPezCount
is used in more than one place and is a fundamental property of a pez dispenser so it is declared as a member variable.
