Basic OOPS Interview Question - 2

Introduction:

In the world of software development, Object-Oriented Programming (OOP) is a fundamental concept that has revolutionized the way we approach software design and development. It provides a powerful and organized way to structure code and create reusable and maintainable software systems. As a result, OOP has become an essential skill for developers in various programming languages. In this Nithra jobs, we have given the key principles and concepts of oops interview questions and how they can be applied to develop robust and scalable software solutions.

1. What is OOPS? Object-Oriented Programming System

2. What is an object of a class? an element (or instance) of a class;

3. How many types of inheritance in oops? Five

4. Encapsulation may be considered to be the same as _______. information hiding

5. Which feature of OOPs helps in deriving a class from another class? Inheritance

6. How is exception handling done in OOPs? Built upon three keywords: try, catch, and throw

7. How could data abstraction be achieved? Classes

8. An instance of Oracle is used in what operations? Oracle background processes

9. _________ function is not a member of the class. Friend function

10. What is the concepts means determining at runtime what method to invoke? Dynamic binding

11. Object Oriented Programming uses ______ approach. Bottom-up

12. What is the OOPs concept only gives calling functions access to the data they need? Encapsualtion

13. What did the oops concept is used as a reuse mechanism? Inheritance

19. In which constructor has no parameters? default constructor

20. In which cannot be used with the keyword virtual? Constructor

21. Runtime polymorphism is accomplished by _____. Function overriding, Virtual functions.

22. What is the doesn't come under OOP concept? Platform independence

23. What is the main goal of Object-oriented programming? Ease of evolution

24. Hiding complexity can also be termed as. Abstraction

25. What is not the basic element of OOP? BlueJ

Conclusion:

OOP is not just a theoretical concept but a practical approach that can significantly enhance the quality, maintainability, and extensibility of your software projects. Understanding Object-Oriented Programming (OOP) is crucial for any developer looking to excel in their career. Practise these oops coding questions and answers and apply the given principles in your coding endeavors to become a proficient OOP developer.
