MAX_PEZ

When this happens, public void load() {load(MAX_PEZ);}, won't it be adding 12 pez to however many pez are already in there, going over the maximum amount then?

Hello Adam,

I believe you are referring to the lesson on overloading the load method where Craig has:

      public void load() {
         load(Max_Pez);
     }

     public void load(int pezAmount) {
         mPezCount += pezAmount;
     }

Nice eye! You are correct. There is a an oversight here in regards to overfilling mPezCount. However, Craig did this intentionally to introduce new developers to this kind of mistake and introduce Exceptions. You can see this by watching his video on method signatures again at 3:42 as well as his next video, Exceptions.

I hope this helps.

Regards,

Chris

Hi there,

To prevent it from going over the limit of 12, the method is defined like so-

public void load() { mPezCount = MAX_PEZ; }

This way, the load method will take however many are currently loaded (mPezCount) and set it to the limit (MAX_PEZ). No addition is taking place, so it can't go over this way.

Christopher is correct, Craig does show you how to fix this in the next video, so continue on and fix that bug!
