What are the OOPS concepts? Explain

Question

Accepted Answer

OOPS concepts are the fundamental principles of Object-Oriented Programming that help in designing and implementing software.

Encapsulation: Bundling data and methods together in a class to hide the internal details.
Inheritance: Creating new classes from existing classes to reuse code and establish a hierarchical relationship.
Polymorphism: The ability of objects to take on many forms, allowing methods to be overridden and objects to be treated as instances of their parent class or interfaces.
Abstraction: Representing essential features without including the background details.
Encapsulation, inheritance, and polymorphism together form the pillars of OOP.
Example: In a banking application, a 'BankAccount' class can encapsulate data like account number and balance, and methods like deposit and withdraw.
Example: Inheritance can be seen in a 'SavingsAccount' class inheriting from the 'BankAccount' class, inheriting its properties and methods.
Example: Polymorphism allows a 'BankAccount' object to be treated as a 'SavingsAccount' object, enabling the use of specific methods.
Example: Abstraction can be achieved by creating an abstract class 'Shape' with common methods like 'calculateArea', which can be implemented by concrete classes like 'Circle' and 'Rectangle'.
