Imperative Programming Paradigm: Imperative programming focuses on HOW to execute program logic and defines control flow as statements that change a program state. Now, these paradigms can be further classified based:ġ. There are mainly two types of Programming Paradigms: Programming paradigms refers to the method of classification of programming languages based on their features. What are some other programming paradigms other than OOPs?
Some of the major Object-Oriented Programming languages include:Ĥ. The programming languages that use and follow the Object-Oriented Programming paradigm or OOPs, are known as Object-Oriented Programming languages. What are some major Object Oriented Programming languages?

Even very big software can be easily written and managed easily using OOPs.ģ.

With OOPs, the readability, understandability, and maintainability of the code increase multifold.OOPs helps users to understand the software easily, although they don’t know the actual implementation.There are many reasons why OOPs is mostly preferred, but the most important among them are: Objects can be considered as real-world instances of entities like class, that have some characteristics and behaviors. It is the programming paradigm that is defined using objects. OOPs refers to Object-Oriented Programming. In fact, the OOPs model is so popular, that many of the most widely used programming languages support and use this Object Oriented Programming or OOPs model, such as Java, C++, Python, C#, etc.īasic OOPs Interview Questions 1.
This gives the OOPs model significance and makes it diverse in its implementation. The concept of “objects” allows the OOPs model to easily access, use and modify the instance data and methods, interact with other objects, and define methods in runtime (during the execution of the program). Behavior = How to start the car? How to change the gear of the car? etc.Ĭharacteristics are also known as data, attributes, or properties, and Behaviours are also known as the functions, procedures or methods, in the programming language.Characteristics = What is the color of your car? What is the Chassis number of your car? etc.Object = A specific car of any model, like the car you own.Class = A specific car model, such as Audi A4, BMW I8, Maruti Suzuki Vitara Brezza, etc.The term “ characteristics” refers to the “what” about the Object, and the term “ behavior” refers to the “how” about the Object.įor example, if we consider a car, then based on the OOPs model:
So the Objects are considered the instance of a class, and are therefore sometimes called “ instances”. In simple language, a class can be considered as the blueprint or template, based on which objects can be created. Objects can be considered as real-world instances of entities like class, that contain some characteristics and behaviors specified in the class template. OOPs, or Object-Oriented Programming is a programming model or paradigm which revolves around the concept of “ OBJECTS”. What will be the output of the below code? Can we run a Java application without implementing the OOPs concept? What is meant by Garbage Collection in OOPs world? What are access specifiers and what is their significance? How is an abstract class different from an interface? What is the difference between overloading and overriding? What are the various types of inheritance? Are there any limitations of Inheritance? Are class and structure the same? If not, what's the difference between a class and a structure?
What are the various types of constructors in C++? Is it always necessary to create objects from class? What is Compile time Polymorphism and how is it different from Runtime Polymorphism?
