The four main principles of Object-Oriented Programming (OOP) are:
-
Encapsulation: This principle involves bundling the data (attributes) and methods (functions) that operate on the data into a single unit, or class. It restricts direct access to some of the object's components, which helps to protect the integrity of the data and prevents unintended interference.
-
Inheritance: Inheritance allows a new class (subclass) to inherit properties and behaviors (methods) from an existing class (superclass). This promotes code reuse and establishes a hierarchical relationship between classes.
-
Polymorphism: Polymorphism enables objects to be treated as instances of their parent class, allowing for methods to be defined in a way that they can operate on objects of different classes. This can be achieved through method overriding (where a subclass provides a specific implementation of a method already defined in its superclass) and method overloading (where multiple methods have the same name but different parameters).
-
Abstraction: Abstraction involves hiding complex implementation details and exposing only the necessary features of an object. This simplifies the interaction with the object and allows users to focus on high-level operations without needing to understand the underlying complexity.
These principles help in creating organized, modular, and maintainable code in OOP languages.
