Abstraction is the process of hiding the complex implementation details and showing only the essential features of an object. It allows you to focus on the what a system does, rather than how it does it. The goal is to reduce complexity and increase efficiency by providing a simpler interface.
Key Points about Abstraction
Hiding Complexity: With abstraction, you focus on what is necessary and hide the unnecessary complexities.
Exposing only Essential Features: In real-world examples, an object might have many properties and methods, but you only expose what is needed and hide others.
Types of Abstraction
We can achieve Abstraction in two ways.
1. Using Abstract Classes
2. Using Interfaces
