What are OOPS Concepts

Question

Accepted Answer

OOPS Concepts are the fundamental principles of Object-Oriented Programming.

Encapsulation - bundling of data and methods that operate on that data
Inheritance - ability of a class to inherit properties and methods from a parent class
Polymorphism - ability of objects to take on multiple forms or have multiple behaviors
Abstraction - hiding of complex implementation details and showing only essential features

Accepted Answer

Four pillars of Object oriented programming are:-

Abstraction: This is  a thought process. It's about deciding which aspects of an object are essential and should be exposed, and which can be hidden. It's a mental exercise in simplification.

Encapsulation: This is primarily an implementation detail. It's how you achieve abstraction in code by bundling data and methods within a class and controlling access to them.

Inheritance: This is a mechanism for code reuse and creating hierarchical relationships between classes.
 
Polymorphism: This is a behavior-based concept. It's the ability of objects to take on multiple forms or behaviors based on context.
