What is Abstraction?

Abstraction facilitates the easy conceptualization of real world objects, by eliminating the unnecessary details of the object. Unnecessary details? Yes, all the similar objects when you generalize, you will drop the uncommon details about the objects.

Abstraction is the process or result of generalization by reducing the information content of a concept, typically to retain only information which is relevant for a particular purpose.

In computer programming, abstraction can apply to control or to data:
1. Control abstraction is the abstraction of actions,
2. data abstraction is that of data structures.

The recommendation that programmers use abstractions whenever suitable in order to avoid duplication (usually of code) is known as the abstraction principle.

Abstraction :

In short Abstraction is "To represent the essential feature with out representing the back ground details. "

-->Abstraction is thinking about something a certain way
. Abstraction is the representation of only the essential features of an object and hiding un essential features of an object.
. Through Abstraction all relevant data can be hide in order to reduce complexity and increase efficiency
. Abstraction is simplifying complex reality by modeling classes appropriate to the problem
. Abstraction-outer layout, used in terms of design
. Encapsulation protects abstraction.
. It taking required data and hiding the unwanted data.

Abstraction is the representation of on an objects activity hiding its working operation.
For example a car object can increase or decrease the speed by using the speedUp() or speedDown() methods, without knowing their implementations.

Hi,

Abstraction is incomplete class, which will be initialize through derived class and make them complete so that we can create an instance of class and use there methods using overridden keyword..

It is actually used to show information of the class without showing the actual code

A real world example, consider u have setup a big building(say a company), the details regarding materials used to built (glass, bricks), type of work, manager of the company, number of floors, design of the building, cost of the building etc. can be classified as ABSTRACTION.

Abstraction in Object Oriented Programming helps to hide the irrelevant details of an object. Abstraction is separating the functions and properties that logically can be separated to a separate entity which the main type depends on.
