Object-Oriented Programming (OOP) is a fundamental programming paradigm widely used in software development. If you're preparing for an interview focused on OOP concepts, this guide provides an in-depth exploration of commonly asked questions, along with explanations and examples. Basic OOP Concepts 1. What is Object-Oriented Programming (OOP)? OOP is a programming paradigm based on the concept of "objects," which can contain data (fields) and code (methods). It facilitates modularity, reusability, and scalability. Key principles of OOP include: Encapsulation: Bundling data and methods operating on that data within a single unit (class). Inheritance: Mechanism to derive new classes from existing ones. Polymorphism: Ability to present the same interface for different data types. Abstraction: Hiding implementation details and showing only the functionality. 2. What is the difference between a class and an object? Class: A blueprint for creating o...

Introduction Object-Oriented Programming (OOP) is a widely used programming paradigm that has been in existence for several decades. It is a programming methodology that is based on the concept of "objects" which are instances of classes that encapsulate data and methods to manipulate that data. OOP allows for the creation of reusable, modular, and scalable code. OOP is used in various programming languages like Java, Python, C++, etc. and it is important for developers to have a good understanding of OOP concepts to create efficient and effective code. In this blog, we will discuss some OOP interview questions that may be asked during interviews. What is OOP? OOP stands for Object-Oriented Programming.
