OOP folks, when is the right time to use inheritance over composition?

Question

OOP

Hello!
3 years ago, after disappointment in inheritance, I switched to using composition + interfaces. I am satisfied, but, nevertheless, I want to reconsider my radical views on this paradigm.
Tell me, when is it right to use inheritance instead of composition?
Thank you!

Answer 1

Inheritance describes the general behavior, interfaces describe the access method.

Answer 2

advice - do not bother. when exactly you need a class hierarchy with inheritance. you will feel it

3 years ago, after disappointment in inheritance..

Does that mean the total experience is definitely at least 3+? ;))
.. I'm generally more and more drawn to the functional paradigm. but in sharpe it is somehow almost all within LINQ .. I look at F #))
the transition is not a transition, but the combination can definitely give interesting results))

Answer 3

The Gang of Four recommends that composition be preferred by default. Inheritance is heavily overrated. In most cases, even the interface is not needed.
