Can you describe the main principles of object-oriented programming?

Principles of Object-Oriented Programming (OOP):

1. Encapsulation — combining data and methods that work with this data into a single object. This allows hiding internal implementation details and protecting data from direct external access.

2. Inheritance — a mechanism that allows creating new classes based on existing ones, inheriting their properties and behaviors, which promotes code reuse.

3. Polymorphism — the ability of objects of different classes to respond differently to the same messages (method calls). This enables using a single interface to work with different types of objects.

4. Abstraction — highlighting the essential characteristics of an object while hiding implementation details. It allows working with objects through their interfaces without delving into details.

These principles help create flexible, extensible, and maintainable programs by modeling real objects and their interactions.
