What are the principles of OOP?

The main principles of object-oriented programming (OOP) include:

• Encapsulation — hiding the internal implementation of an object and providing access only through public methods.
• Inheritance — the ability to create new classes based on existing ones, inheriting their properties and methods.
• Polymorphism — the ability of objects of different classes to process the same messages differently, for example, through method overriding.
• Abstraction — highlighting the essential characteristics of an object, hiding non-essential details.

These principles help create more modular, extensible, and maintainable code.
