Explain all the oops concepts

Question

Accepted Answer

Object-oriented programming concepts that help in designing and implementing software systems.

Encapsulation: Bundling of data and methods into a single unit (class) to hide implementation details.
Inheritance: Ability to create new classes (derived classes) from existing classes (base classes) to reuse code and extend functionality.
Polymorphism: Ability of objects of different classes to respond to the same message in different ways.
Abstraction: Representing essential features without including implementation details.
Encapsulation, inheritance, and polymorphism together form the pillars of object-oriented programming.
Example: A class 'Car' encapsulates data like 'color' and methods like 'startEngine'.
Example: Inheritance allows creating a class 'SUV' derived from 'Car' to inherit its properties and add new ones.
Example: Polymorphism enables a method 'drive' to behave differently for 'Car' and 'SUV' objects.
Example: Abstraction allows creating a class 'Vehicle' with common features shared by 'Car' and 'SUV'.

Accepted Answer

Encapsulation:-Encapsulation is a feature of an entity that holds all secret data. Only the members of that class can see the details.
 
 Data hiding- Only showing the data that is necessary to the user
 
 Inheritance- Inheriting data of one class by another class
 
 Polymorphism- executing one operation in different ways.
