Object-oriented design is the process of planning a system of interacting objects for the purpose of solving a software problem. It is one approach to software design.

What is object-oriented with example?

Significant object-oriented languages include Java, C++, C#, Python and Javascript. The simplest way to explain object-orientated programming to a kid is to use something like a car as an example. A car has a model name, a colour, a year in which it was manufactured, an engine size and so on.

Why object oriented design is used?

Object-oriented programming is ultimately about taking a huge problem and breaking it down to solvable chunks. For each mini-problem, you write a class that does what you require. And then — best of all — you can reuse those classes, which makes it even quicker to solve the next problem.

Why it is called as object-oriented?

C++ is called object oriented programming (OOP) language because C++ language views a problem in terms of objects involved rather than the procedure for doing it.

What are the 4 basics of OOP?

The main ideas behind Java’s Object-Oriented Programming, OOP concepts include abstraction, encapsulation, inheritance and polymorphism.
Java defines OOP concepts as follows:

  • Abstraction. Using simple things to represent complexity. …
  • Encapsulation. …
  • Inheritance. …
  • Polymorphism.

What are the 3 principles of OOP?

Object-Oriented Principles. Encapsulation, inheritance, and polymorphism are usually given as the three fundamental principles of object-oriented languages (OOLs) and object-oriented methodology. These principles depend somewhat on the type of the language.

What is OOP and its features?

Object-oriented programming (OOP) is a computer programming model that organizes software design around data, or objects, rather than functions and logic. An object can be defined as a data field that has unique attributes and behavior.

How do you use object oriented design?

In this step, the operation to be performed on objects are defined by combining the three models developed in the OOA phase, namely, object model, dynamic model, and functional model. An operation specifies what is to be done and not how it should be done.

What is OOP principle?

There are 4 major principles that make an language Object Oriented. These are Encapsulation, Data Abstraction, Polymorphism and Inheritance.

What are the 5 Oops concepts?

An Introduction to OOPS Concepts in Java | Abstraction Inheritance Polymorphism

  • Objects & Classes. Objects are the basic unit of OOPS representing real-life entities. …
  • Abstraction. …
  • Encapsulation. …
  • Inheritance – Single, Multilevel, Hierarchical, and Multiple. …
  • Polymorphism – Static and Dynamic.

What is the best OOP language?


JAVA. Java is much more than just a high-level programming language. Java is one of the best and most widely-used OOP in the market today. Java has come a long way and is widely known for its implementation and strategic development.


– Information Technology. HTML is an Object Oriented Programming Language.

Why Oops is important?

Benefits of OOP

OOP language allows to break the program into the bit-sized problems that can be solved easily (one object at a time). The new technology promises greater programmer productivity, better quality of software and lesser maintenance cost. OOP systems can be easily upgraded from small to large systems.

Why Java is not object-oriented?

Java is not fully object oriented because it supports primitive data type like it,byte,long etc.,which are not objects. Because in JAVA we use data types like int, float, double etc which are not object oriented, and of course is what opposite of OOP is.

Who invented OOP?

“Object-Oriented Programming” (OOP) was coined by Alan Kay circa 1966 or 1967 while he was at grad school. Ivan Sutherland’s seminal Sketchpad application was an early inspiration for OOP. It was created between 1961 and 1962 and published in his Sketchpad Thesis in 1963.

Which language is pure OOP?

int, long, bool, float, char, etc as Objects: Smalltalk is a “pure” object-oriented programming language unlike Java and C++ as there is no difference between values which are objects and values which are primitive types. In Smalltalk, primitive values such as integers, booleans and characters are also objects.
