Certainly! Here are the top 20 interview questions and answers on Object-Oriented Programming (OOP): What is Object-Oriented Programming (OOP)? Answer: Object-Oriented Programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data and code. It allows for the organization of software into reusable components and promotes concepts like encapsulation, inheritance, and polymorphism. What are the main principles of OOP? Answer: The main principles of OOP are: Encapsulation: Bundling data and methods that operate on the data into a single unit. Inheritance: The ability of a class to inherit properties and behavior from another class. Polymorphism: The ability to use the same interface for different types or forms. What is a class in OOP? Answer: A class in OOP is a blueprint or template for creating objects. It defines the properties (attributes) and behaviors (methods) that objects of the class will have. What is an object in OOP?
