abstraction in oop java

What is abstraction in OOP with example?
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._{3 août 2022}
Why use abstraction in OOP?
Abstraction in OOPS is used to hide unnecessary information and display only necessary information to the users interacting.
It is essential to represent real-world objects in a simplified manner for users to interact easily.
What is types of abstraction in Java?
There are two main types of abstraction in Java: interface and abstract class.
Interface Abstraction is a way of defining the public methods that a particular type of object must implement without having to define how those methods work.
Abstraction is a way of representing some specific data.
Encapsulation is a way of hiding the complexity of something and exposing only the parts you wish to expose.
For example, if you have a class that has one or more private fields that you use to store the data, then you are in encapsulation.

Abstraction in Java is a fundamental concept of Object-Oriented Programming (OOP) that hides the complexity of the code and shows only the essential features to the user. It is achieved using abstract classes and interfaces, such as abstract class Animal { abstract void makeSound(); } .
