Question

Accepted Answer

The 4 pillars of OOP are Abstraction, Encapsulation, Inheritance, and Polymorphism.

Abstraction: Hiding implementation details and showing only necessary information. Example: A car dashboard only shows necessary information like speed, fuel level, etc.
Encapsulation: Binding data and methods that manipulate the data together. Example: A bank account class with methods to deposit, withdraw, and check balance.
Inheritance: Creating new classes from existing ones, inheriting their properties and methods. Example: A class Animal can be inherited by classes like Dog, Cat, etc.
Polymorphism: Ability of objects to take on multiple forms. Example: A method can take different forms depending on the object it is called on.

Accepted Answer

There are four major pillors of oops concept that are Inheritance,Polymorphism,Abstraction, and Encapsulation, Any software lagnuage which satisfy these four oops concepts are purely object oriented programming language.

Let's understand these concepts in detail.

Inheritance: When child class acquires all the properties and behaviour of parent class it is called Inheritance.

there are five types of inheritance are:-

1. Single level inheritance.

2. Multi level inheritance.

3. Multiple inheritance.

4. Hybrid inheritance.

5. Hirarchical inheritance.

Polymorphism: Polymorphism is a concept by which we can perform a single task in different ways. we can perform polymorphism in java by method overloading and mehod overriding.

Abstraction: Abstraction is process of hiding the implementation details and showing functionallity to the user.

or, abstraction shows only essential things to the user hides internal details.

Encapsulation: The idea of bundling data and methods that work on that data within one unit, like a class in java,
