Best way in terms of OOP?

Question

OOP

I’ll ask a slightly stupid question, but then I thought, what is the best way to provide an array, say, from a class to a function, from the point of view of OOP?
Publish an existing object and give access to it through a dot (read-only, not for modifications)
Or create a method like public: List get_list() and return this array, reading it through this method, and make the array itself private?

Answer 1

in my opinion, from the point of view of OOP (namely, encapsulation), - access to a variable / array is possible only from a class function; And so get() and set() must be implemented for this variable.

Answer 2

The whole essence of OOP is that outside you can not work with any data of the class, only through methods.
