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
