Abstraction

Abstraction in computer programming is a way to reduce complexity and allow efficient design and implementation in complex software systems. It hides the technical complexity of systems behind simpler APIs.

Helps the user to avoid writing low-level code. Avoids code duplication and increases reusability. Can change the internal implementation of a class independently without affecting the user. Helps to increase the security of an application or program as only important details are provided to the user.
