OOP concepts in one simple program

Question

Hello everyone.
I am wondering if someone can put all possible OOP elements in one single program. So that we understand the practical use of OOP in real projects.
All that I have learnt about OOP is individual examples of each concepts.
I want see how I can use them effectively in my coding.

**Please use Python, Java or Javascript**
Thanks.

Answer 1

There are a lot of overlapping areas when we talk about OOP concepts, for example a class inheriting from other class is not just an example of inheritance but also encapsulation.
So it might end up confusing you.

Answer 2

While jump into design patters the OOP complexity grows dramatically

OOP facts:
*encapsulation & accessibility
*abstraction
*composition
*inheritance
*polymorphism
*modularity
*instantiation

those are the main, but there are much more, every branch split in branches with more concrete concepts.
