What are the main principles of object-oriented programming you can identify?

Encapsulation: Hiding data and implementations inside an object, accessed through specific methods. It ensures modularity and protects data from incorrect access.

Inheritance: Creating new classes (children) based on existing ones (parents), inheriting their properties and methods. It allows code reuse and the creation of class hierarchies.

Polymorphism: The ability of objects of different classes to respond differently to the same method call. Achieved through method overriding in subclasses or using protocols.

Abstraction: Highlighting the most important characteristics of an object and ignoring less significant details. It allows working with objects at a high level, hiding unnecessary complexity.
