In chapter 2 of K & B book, 2 mins drill down following statement is written. Can any body explain with an example?

Object type (not the reference variable's type), determines which overridden
method is used at runtime.

I think it refers to such a case:

Object type(here, Dog) (not the reference variable's type, here Animal), determines which overridden method is used at runtime. Dog's eat method will be called.

Hi Narendra shah,

Object type (not the reference variable's type), determines which overridden
method is used at runtime.


it is actually the definition for overriding. right? The method, which will be called is determined by the type of object at runtime, not by the refence used.
