what are pillars of OOPS

Question

Accepted Answer

The pillars of OOPS (Object-Oriented Programming) are Inheritance, Encapsulation, Polymorphism, and Abstraction.

Inheritance allows a class to inherit properties and behavior from another class. For example, a 'Car' class can inherit from a 'Vehicle' class.
Encapsulation refers to the bundling of data with the methods that operate on that data. It restricts access to some of an object's components. For example, using private variables in a class.
Polymorphism allows methods to do different things based on the object they are acting upon. For example, a 'draw' method can behave differently for a 'Circle' object and a 'Square' object.
Abstraction refers to the concept of hiding the complex implementation details and showing only the necessary features of an object. For example, using abstract classes or interfaces.
