This article will discuss about the Abstraction and also we will see the difference between the Abstraction and encapsulation.
What is an Abstraction?
• 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.
In this above example abstraction shows only necessary details of car or shows only necessary details to drive a car like rear view mirror, gear, clutch, steering And hides internal detail of car like Piston, crankshaft, carburetors, gas turbines etc which is encapsulation for a car.
Abstraction shows only required data and hides unwanted data.
Difference between Encapsulation and Abstraction
| 1. Abstraction solves the problem in the design level |
1. Encapsulation solves the problem in the implementation level |
| 2. Abstraction is used for hiding the unwanted data and giving relevant data |
2. Encapsulation means hiding the code and data in to a single unit to protect the data from outside world |
| 3. Abstraction is a technique that helps to identify which specific information should be visible and which information should be hidden. |
3. Encapsulation is the technique for packaging the information in such a way as to hide what should be hidden, and make visible what is intended to be visible. |
In this above example abstraction shows only necessary details of car or shows only necessary details to drive a car like rear view mirror, gear, clutch, steering And hides internal detail of car like Piston, crankshaft, carburetors, gas turbines etc which is encapsulation for a car
Abstraction shows only required data and hides unwanted data .
In above example which shows encapsulated detail of a car which is not necessary to expose to outside world and make visible what is intended to be visible.
