In the example file when he used the PezDispenser class, he referred to it as the variable type to. Just trying to understand why that is a variable type.

They are always lowercase 'Objects' can do many things (defined as methods) and contain lots of properties (often defined as other primitives or Strings). They are always uppercase (like your PezDispenser)

Courses Plus Student 8,592 PointsLater on when you create PezDispenser objects (instances of the PezDispenser class), you could create a variable to represent the PezDispenser object:
PezDispenser pd = new PezDispenser(...);
In this case, pd is a variable (or object) of type PezDispenser.

1,259 PointsThank you Rebecca!!!! I finally understand it now. Objects, classes, and methods were always such an abstract concept to wrap my head around and I am beginning to really understand it now. Thank you very much!

1,259 PointsThanks John. I forgot that Objects were also considered data types not just int, double etc. That's probably another reason I wasn't completely getting it.
