abstraction in oops

What is abstraction in OOP?
Abstraction is a general concept which you can find in the real world as well as in OOP languages. Any objects in the real world that hide internal details provide an abstraction. The objects may be your coffee machine or classes in your current software project,
What is the difference between abstraction and encapsulation in object oriented programming?
Abstraction in Object Oriented Programming solves the issues at the design level. Encapsulation solves it implementation level. Abstraction in Programming is about hiding unwanted details while showing most essential information. Encapsulation means binding the code and data into a single unit.
What is the difference between abstraction and polymorphism in OOP?
Abstraction and polymorphism are closely related concepts in OOP. Abstraction enables polymorphism by providing a common interface that multiple classes can implement. Polymorphism allows objects of different concrete classes to be treated as instances of a shared abstract class or interface. This promotes code flexibility and extensibility.
What is an example of abstraction?
Your car is a great example of abstraction. You can start a car by turning the key or pressing the start button. You don’t need to know how the engine is getting started, what all components your car has. The car internal implementation and complex logic is completely hidden from the user.

Abstraction in OOP

Objects in an OOP language provide an abstraction that hides the internal implementation details. Similar to the coffee machine in your kitchen, you just need to know which methods of the object are available to call and which input parameters are needed to trigger a specific operation. But you don’t need to understand how this method is implemente

Different Types of Abstraction

There are primarily two types of abstraction implemented in OOPs. One is data abstraction which pertains to abstracting data entities. The second one is process abstraction which hides the underlying implementation of a process. Let’s take a quick peek into both of these. stackify.com

Abstraction in Action

Now that we understand abstraction well, let’s see how we can implement it. Since I’ve spun my coffee stories so much already, let’s actually go ahead and implement the coffee machine example in Java. You do the same in any other object-oriented programming language. The syntax might be a little bit different, but the general concept is the same. stackify.com

Abstraction vs Encapsulation

A lot of times programmers often confuse abstraction with encapsulation because in reality the two concepts are quite intertwined and share a relationship between them. Abstraction, as we’ve seen pertains to hiding underlying details and implementation in a program. Encapsulation, on the other hand, describes how abstraction occurs in a program. Ab

Summary

Abstraction is a general concept which you can find in the real world as well as in OOP languages. Any objects in the real world that hide internal details provide an abstraction. The objects may be your coffee machine or classes in your current software project, These abstractions make it a lot easier to handle complexity by splitting them into sm
