Question

Accepted Answer

OOPS stands for Object-Oriented Programming System. It includes concepts like polymorphism, abstraction, inheritance, and encapsulation.

Polymorphism allows objects of different classes to be treated as objects of a common superclass. Example: a shape class with subclasses like circle and square.
Abstraction is the concept of hiding the implementation details and showing only the necessary features of an object. Example: a car class with methods like start() and stop() without revealing the internal engine workings.
Inheritance allows a class to inherit properties and behavior from another class. Example: a vehicle class with subclasses like car and bike inheriting common attributes like speed and fuel capacity.
Encapsulation is the bundling of data and methods that operate on the data into a single unit. Example: a bank account class with private variables like balance and methods like deposit() and withdraw() to access them.
