The four pillars of Object-Oriented Programming (OOP) are:
Encapsulation: Encapsulation is the process of hiding the internal implementation details of an object and exposing only the necessary information and methods to the outside world. It involves bundling data (attributes or properties) and the methods (functions or behavior) that operate on that data into a single unit called a class. Encapsulation helps in achieving data abstraction, information hiding, and maintaining the integrity of the object's state.
Inheritance: Inheritance is a mechanism that allows one class to inherit properties and methods from another class. Inheritance enables the creation of a hierarchy of classes, where a child class (or subclass) inherits characteristics (attributes and methods) from a parent class (or superclass). It promotes code reusability and provides a way to model relationships and common behaviors between classes.
Polymorphism: Polymorphism is the ability of objects of different classes to respond to the same method or message. It allows objects of different classes to be treated as if they were of the same type, as long as they implement the same method or interface. Polymorphism enables writing generic code that can work with different types of objects, making code more flexible and extensible.
Abstraction: Abstraction is the process of simplifying complex systems by breaking them down into smaller, more manageable parts. It involves creating abstract classes or interfaces that define common attributes and methods without providing any implementation details. Abstraction allows for the creation of reusable templates or blueprints for classes, providing a high-level view of the system and promoting code modularity and maintainability.
These four pillars of OOP provide a solid foundation for designing and building complex software systems, allowing for code organization, encapsulation of data and behavior, code reuse, and flexibility in handling different types of objects.
