But as the number of customers grows it becomes really difficult to keep track of all these variables and manipulating them every time you need to perform some operation on them becomes a nightmare.Īlso there is always a possibility that some other part of your program might unintentionally modify these values which can lead to serious consequences. You would most probably start by creating individual variables like account Number, customer Name etc. Now think about how would you approach this problem if you had to use conventional programming methodologies. You will also need to provide them with certain services like cash withdrawal, money transfer, balance enquiry etc. So basically, you need to store their account number, name, date of birth, address, phone number etc. This software will maintain the records of all the customers who have an account in that particular bank. Still confused? Let's take an example:Ĭonsider a scenario where you are required to develop software for a bank. Most popularly known languages that follow the OOP paradigm are Java, C++ etc. The main purpose of OOP is to bind code and data together, making it difficult to modify the data without affecting the code and vice versa. Object-oriented programming aims to implement real-world entities like inheritance, hiding, polymorphism etc., in programming.

A feature of objects is an object's behavior or its ability to perform actions. Object-oriented programming (OOP) is a programming paradigm based on the concept of 'objects', which can contain data, in the form of fields, and code, in the form of procedures. By encapsulating data and methods into logical units (objects), programmers can more easily modularize their code and make changes in one area without affecting other areas of the codebase.Įxpect to come across this popular question in OOPS interview questions. Additionally, object-oriented programming can help to make code more maintainable and easier to understand. For example, if you have written a method for sorting an array of integers, you can easily reuse that method in another program by creating a new object that uses the sorting method. One advantage of object-oriented programming is that it can help to promote code reuse. In addition, object-oriented programming languages typically provide mechanisms for organizing code into modular units (objects), which can be reused in other programs. In object-oriented programming, programmers define not only the data type of a data structure, but also the types of operations (methods) that can be applied to the data structure. Object-Oriented Programming, or OOP for short, is a style of programming that encourages the use of objects and methods. From beginner to expert level, this course will help boost your coding skills and prepare for success in your next software development job interview. With this knowledge in mind, you'll be equipped to answer difficult OOP interview questions confidently. We will look at basic programming principles, polymorphism and inheritance as well as advanced topics such as design patterns, multithreading and memory management. This course will provide you with a comprehensive overview of the concepts and levels of OOP compiled in different sections for beginner level, intermediate level & advanced level users. Object Oriented Programming Interview Questions are an important part of any software development job interview. It allows for efficient data management, code reuse and easy debugging. Object Oriented Programming is a programming paradigm that uses objects, classes and other abstractions to model the real world. OOPS Interview Questions and Answers Programming
