Oops concepts with example

Question

Accepted Answer

Oops concepts are fundamental principles of object-oriented programming.

Encapsulation: bundling data and methods together in a class
Inheritance: creating new classes from existing ones
Polymorphism: objects of different types can be treated as objects of a common superclass
Abstraction: hiding unnecessary details and exposing only essential features
Encapsulation example: a Car class with private variables for make, model, and year, and public methods to access and modify them
Inheritance example: a Dog class inheriting from an Animal class, inheriting common properties and methods
Polymorphism example: a Shape superclass with a draw() method, and Circle and Rectangle subclasses overriding the draw() method
Abstraction example: an Animal superclass with abstract methods like eat() and sleep(), and specific animal subclasses implementing those methods
