Object oriented programming - class design confusion

Question

I am trying to wrap my head around object oriented programming.

My understanding is that we have objects so we can design our programs to mirror real-life objects.

Answer 1

I don't think we should try to "mirror real-life objects". I think it's more of finding real life objects that closely resemble the behavior being modeled within the context of the system (domain). A Fruit class in a game where you slice fruit for points might have drastically different behaviors and attributes than the Fruit class in a game where a character runs around collecting fruits for points; or a simulation of people eating fruits. Assigning behaviors to classes named after real life objects makes it easier to assume the behavior of code modules and speculate on their interactions.
