Dispense Method

Would the implementation of the dispense() Method be okay if i do it like this:

public boolean dispense() {
    boolean wasDispensed;

    if (!isEmpty()) {
        mPezCount--;
        wasDispensed = true;
    }else{
        wasDispensed = false;
    }

    return wasDispensed;
    }

instead of : public boolean dispense() { boolean wasDispensed = false; if (!isEmpty()) {

mPezCount--; wasDispensed = true; }

return was Dispensed; }

Yes. Your implementation would work. It's just not as clean as doing it the other way. Essentially you're doing the same thing just with a bit more code.

As a programmer, you want to keep your code as clean as possible. That way you won't get confused if you look back on it in the future and so others can read it without any issues. :)
