Q2. OOPS - Abstraction and how can we achieve it?
Ans. 
Abstraction in OOPS is the concept of hiding the implementation details and showing only the necessary information to the user.
• Abstraction can be achieved in OOPS by using abstract classes and interfaces.

• Abstract classes have at least one abstract method that must be implemented by the subclasses.

• Interfaces define a set of methods that a class must implement.

• By using abstraction, we can focus on the essential features ...read more

Q1. What are oops describe the paradigm.
Ans. 
Object-oriented programming paradigm focuses on objects and classes to organize code and data.
• Objects are instances of classes that encapsulate data and behavior

• Classes define the blueprint for creating objects

• Inheritance allows classes to inherit properties and methods from other classes

• Polymorphism enables objects to be treated as instances of their parent class

• Encapsulation restricts access to certain components of

Q2. What are oops concept
Ans. 
Object-oriented programming concepts that focus on classes and objects
• Encapsulation: bundling data and methods that operate on the data into a single unit (class)

• Inheritance: ability of a class to inherit properties and behavior from another class

• Polymorphism: ability to present the same interface for different data types

• Abstraction: hiding the complex implementation details and showing only the necessary features
