🔑 OOP Principles Summary
Encapsulation: Wrapping data and code into a single unit (class) and restricting access to details.
Inheritance: One class inherits properties and behavior from another.
Polymorphism: Ability of one interface to be used for different data types.
Abstraction: Hiding implementation details and only exposing the essential features.
