Welcome to the final installment of our five-part series on SOLID principles. In this blog, we’ll deep dive into the ‘D’ in SOLID. Get ready to explore the core concept of the Dependency Inversion Principle and discover how it can revolutionize your approach to software development.

The Dependency Inversion Principle (DIP) is one of the SOLID principles of object-oriented design. It emphasizes that high-level modules or classes should not depend on low-level modules but should depend on abstractions. Additionally, it states that abstractions should not depend on details, and details should depend on abstractions. In simpler terms, DIP promotes the use of interfaces or abstract classes to decouple high-level modules from low-level implementation details.

DIP promotes the use of interfaces or abstract classes to decouple high-level modules from low-level implementation details.

Mechanisms to Achieve Dependency Inversion Principle:

To adhere to the Dependency Inversion Principle, consider the following mechanisms:

1. Use of Interfaces or Abstract Classes: Define interfaces or abstract classes that represent the dependencies your high-level modules need. High-level modules can then depend on these abstractions…
