In this article you will learn about characteristics of oops

OOPs ( Object-oriented programming system ) has many Characteristics and some of them you'll find in the below article. I hope you find this article helpful and before going ahead we would suggest you please check e collection of Programming Full Forms with the below link:

What is OOPs (Object-oriented programming system)?

Object-Oriented Programming (OOP) System is a programming paradigm based on the concept of using classes and objects in your programming code. Object-Oriented Programming (OOP) used to structure a programming language into simple, reusable pieces of code that usually known as classes, which we can use as a user define Data Type to create instances of objects. 

Characteristics of Oop’s

OOPs ( Object-oriented programming system ) has many Characteristics like:

  • Class
  • Objects
  • Data Abstraction
  • Data Encapsulation
  • Inheritance
  • Polymorphism

You may be asked many questions about the basic of OOPs in your next interview. So, let's have a quick list of OOPs Interview Questions.

OOPs Interview Questions and Answers

What are the Objects in OOPs ( Object-oriented programming system )?

  • Objects are basic building blocks for designing programs.
  • An object is a collection of data members and associated member functions.
  • An object may represent a person, place or a table of data.
  • Each object is identified by a unique name. Each object must be a member of a particular class.
  • Example: chair, table, whiteboard are the objects of the class (class).

What are the Classes in OOPs (Object-oriented programming system)?

  • The objects can be made user-defined data types with the help of a class.
  • A class is a collection of objects that have identical properties, common behaviour and shared relationship.
  • Once the class is defined any number of objects of that class is created.
  • Classes are user-defined data types A class can hold both data and functions.
  • For example planets, sun and moon are the members of the solar system class.

What is Data abstraction in OOPs (Object-oriented programming system)?

Data abstraction refers to the process of representing essential features without including background details or explanations.

What is Data encapsulation in OOPs (Object-oriented programming system)?

  • The wrapping of data and function into a single unit is called data encapsulation.
  • Data encapsulation enables data hiding and information hiding.

What is Inheritance in OOPs (Object-oriented programming system)?

  • Inheritance is the process by which one object can acquire and the use of properties of another object.
  • The existing class is known as a base class or superclass.
  • The new class is known as a derived class or subclass.
  • The derived class shares some of the properties of the base class. Therefore a code from a base class can be reused by a derived class.

What is Polymorphism in OOPs (Object-oriented programming system)?

  • The ability of an operator and function to take.
  • Multiple forms are known as polymorphism.
  • The different types of polymorphism are operator
  • overloading and function overloading.

SOLID guidelines in OOPs:

SOLID is a mnemonic invented by Michael Feathers that stands for and advocates five programming practices:

  • S: Single responsibility principle
  • O: Open/closed principle
  • L: Liskov substitution principle
  • I: Interface segregation principle
  • D: Dependency inversion principle

List of Top OOPs base languages:

  • C++
  • Java
  • C#
  • Java Script
  • Python
