Table of Contents • • • • • • • Introduction to Object Oriented Programming In this oops interview questions blog first lets talk about Object Oriented Programming (OOP) is an important concept to understand for many software development and IT roles. OOP is a programming methodology that revolves around objects and classes. With OOP, you create objects from classes and manipulate them as entities—rather than dealing with functions or commands—to create a program. In this overview, we’ll discuss the basics of object oriented programming and how it’s used in interviews. At the core of the OOP concept are the class and object. Classes are templates that define the characteristics, features, behaviors, and properties of an object. These characteristics can be expressed as data fields or methods, which are just functions associated with the class. For example, if you were to create a class called “Car,” it would have characteristics like brand name, year manufactured, color, etc., all stored as data fields in a database. Objects are instances of classes that have been instantiated in order to use them within a program or application. For instance, a car class might have multiple objects created from it such as a 2020 BMW M3 Coupe with carbon fiber trim. These objects give us the flexibility to create unique variables for each individual type of car without having to rewrite code each time an important example for the oops interview questions. Object oriented programming is ess...

Object-Oriented Programming, or OOPs, is a programming paradigm that implements the concept of objects in the program. It aims to provide an easier solution to real-world problems by implementing real-world entities such as inheritance, abstraction, polymorphism, etc. in programming. OOPs concept is widely used in many popular languages like Java, Python, C++, etc. OOPs Interview Questions 1. What is Object Oriented Programming (OOPs)? O bject O riented P rogramming (also known as OOPs) is a programming paradigm where the complete software operates as a bunch of objects talking to each other. An object is a collection of data and the methods which operate on that data. 2. Why OOPs? The main advantage of OOP is better manageable code that covers the following: • The overall understanding of the software is increased as the distance between the language spoken by developers and that spoken by users. • Object orientation eases maintenance by the use of encapsulation.One can easily change the underlying representation by keeping the methods the same. • The OOPs paradigm is mainly useful for relatively big software. 3. What is a Class? A class is a building block of Object Oriented Programs. It is a user-defined data type that contains the data members and member functions that operate on the data members. It is like a blueprint or template of objects having common properties and methods. 4. What is an Object? An object is an instance of a class. Data members and methods of a c...

Hello guys, If you have given any coding interview then you know that System design or Software design problems are an important part of programming job interviews, and if you want to do well, you must prepare this topic. In the past, when I shared my list of I had my own list of questions that I have collected from various interviews with friends and colleagues but I needed more questions for this article when I stumbled upon the Grokking System Design Interview course on Educative. It's like a godsend resource because it not only gives you a lot of System design question but also provide all the knowledge and tools you need to solve those questions. In other words, this course teaches you to step by step how to proceed with designing a real-world system like Facebook, Twitter, Uber, etc. Actually, there are not too many system design interview courses. When I was searching I only find Grokking The System Design course by Educative and Preparing for the System Design Interview course on Udemy by Rajat Mehta. Other than that I didn't find any online course which is completely focused on solving system design problems from top companies like Amazon, Google, Microsoft, Apple, SalesForce, Flipcart, etc. Anyway, When you combine this course with this list of questions you will have the best material to prepare for your System design interview. You can also first try all these questions by yourself before joining the course or looking it my solution for some of the questions. B...

If you’re getting ready for your first interview for an Object-Oriented Programming (OOPs) role, congratulations! We know you’ve put in a lot of time and effort to get this far. You’re probably now wondering what kinds of OOPs interview questions to expect. That’s why we’ve put together this list of 13 common OOPs interview questions and how to answer them. Between studying these OOPs-specific questions and our 1. What are OOPs? 2. What are the advantages of OOPs? There are many advantages to OOPs, including: • OOPs abstraction helps make code easier to use and understand. • OOPs reuse code which helps reduce redundancy and save coding time. • OOPs can easily handle and manipulate complex datasets. • OOPs support a lot of flexibility through polymorphism. 3. What are some examples of OOP languages? The most popular OOP languages are: • • • • • • • 4. What are the four main concepts of OOPs? The four main concepts or principles of OOPs are: • Encapsulation • Polymorphism • Inheritance • Abstraction 5. What is encapsulation? For example, if you define an object that contains a list of integers, your object will always include the method used to calculate the average of those integers, even if you can’t access the source code directly. 6. What is polymorphism? 7. What is inheritance? For example, suppose we created an “Animals” class with properties like age and weight. If we create a child class called “Mammals,” we might add mammal-specific traits like hair color. But, as a...
