1,912 PointsWhat if I errase the "return" on the isEmpty boolean?, does it change something?
public boolean isEmpty(){
/*return*/ pezCount == 0; //What if I errase the return?
}

public void isEmpty(){
pezCount = 0;
}
But, the return in your example means To return the value of the logic of checking pezCount equals to zero ( so the value of return will be true to method caller) or not equaling to zero ( value of return false)
