Can you recommend any materials for learning OOP?

Question

Books

I really want to understand the concept of OOP. I need a book or video tutorials where examples explain how to create something in the OOP paradigm

Answer 1

"Clean Architecture" by Robert Martin, one of the first sections talks about the basics of OOP.
Well, it’s worth looking for a book and courses with reference to the learned language, Head First Design Patterns explains well the meaning of OOP concepts in conjunction with patterns, but you need to understand the basics of Java.
