  • Q5. What is oops
  • Ans. 

    OOPs stands for Object-Oriented Programming. It is a programming paradigm based on the concept of objects.

    • Examples of OOPs languages are Java, C++, Python, etc.

  • Answered by AI
  • Q6. Applications of oops
  • Ans. 

    OOPs is used for creating modular, reusable and maintainable code.

    • Encapsulation: Hiding implementation details and exposing only necessary information.

    • Inheritance: Reusing code and creating a hierarchy of classes.

    • Polymorphism: Using a single interface to represent multiple entities.

    • Abstraction: Reducing complexity by hiding unnecessary details.

    • Examples: Java, C++, Python, Ruby, etc.

  • Answered by AI
  • Q7. What is inheritance
  • Ans. 

    Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.

    • Inheritance allows code reuse and promotes code organization.

    • The existing class is called the parent or superclass, and the new class is called the child or subclass.

    • The child class inherits all the properties and methods of the parent class and can also add its own unique properties and ...

  • Answered by AI
  • Q8. What is polymorphism
  • Ans. 

    Polymorphism is the ability of an object to take on many forms.

    • It allows objects of different classes to be treated as if they were objects of the same class.

    • It is achieved through method overriding and method overloading.

    • Example: A parent class Animal can have child classes like Dog, Cat, and Bird, each with their own unique implementation of the method 'makeSound'.

    • Polymorphism makes code more flexible and reusable.

  • Answered by AI
  • Q9. What is abstraction? Explain with example
  • Ans. 

    Abstraction is the process of hiding complex implementation details and exposing only the necessary information.

    • Abstraction helps in reducing complexity and increasing efficiency.

    • It allows us to focus on the essential features of an object or system.

    • For example, a car can be abstracted as a vehicle with certain properties like speed, fuel efficiency, and seating capacity.

    • Abstraction can be achieved through interfaces,

  • Answered by AI
  • Q10. What is encapsulation
  • Ans. 

    Encapsulation is the process of hiding implementation details and providing a public interface for accessing the functionality.

    • Encapsulation helps in achieving data abstraction and information hiding

    • It prevents unauthorized access to the internal details of an object

    • It allows for easy modification of implementation without affecting the external code

    • Example: A class with private variables and public methods
