DI (Dependency Injection)

Dependency Injection (DI) is a design pattern used to implement Inversion of Control, allowing the creation of dependent objects outside of a class and providing those objects to a class in different ways. This pattern helps to decouple the code, making it more modular, testable, and maintainable. DI is commonly used in frameworks and libraries to manage dependencies and configurations.

How does Dependency Injection improve code maintainability?
Dependency Injection improves code maintainability by decoupling classes and their dependencies, making the code more modular, easier to test, and simpler to maintain.
What are the common ways to implement Dependency Injection?
Common ways to implement Dependency Injection include constructor injection, setter injection, and interface injection, each providing different methods for supplying dependencies to a class.
How does Dependency Injection relate to Inversion of Control?
Dependency Injection is a specific implementation of Inversion of Control, where the control of creating dependencies is inverted from the class itself to an external source or framework.
