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

Should a fruit object rather be passed to a human object which has a Eat() function?

Yes.

But program objects are generally more abstract than this naive example. In the real world of computer programming, objects like fruit and humans would generally be represented as attributes in a database. The consumption and manipulation of such data would be done in programming objects.
