Why do you need to cast the apartment objects to room type if there is already an "if instanceof" apartment type statement?

i believe instanceof just checks the status of the object. you still need to cast down to the OneRoomApt to access its methods.

I guess my confusion arised because of the shorthand used to create the object. If I understood correctly, the object was created as an Apartment object because the ArrayList accepts Apartment objects. Is that correct?
