What is abstraction?

Question

Accepted Answer

Abstraction is a fundamental concept in programming that simplifies complex systems by hiding unnecessary details.

Simplification: Abstraction allows developers to focus on high-level functionalities without getting bogged down by implementation details.
Example: In a car, the driver uses the steering wheel and pedals without needing to understand the inner workings of the engine.
Interfaces: Abstraction is often implemented through interfaces or abstract classes in object-oriented programming, defining methods without specifying how they work.
Example: A payment processing system may provide an interface for processing payments, while different payment methods (credit card, PayPal) implement the details.
Encapsulation: Abstraction is closely related to encapsulation, where data and methods are bundled together, restricting access to certain components.
