Dependency Injection

Summary

Dependency Injection is a design pattern used in software development that allows for the decoupling of components by injecting dependencies into a class rather than having the class create its own dependencies.

Detailed Description

In Dependency Injection (DI), an object's dependencies (other objects it interacts with) are provided externally, allowing for greater flexibility and easier testing. This practice improves code maintainability and promotes the single responsibility principle. DI can be implemented through constructor injection, property injection, or method injection, where the dependencies are supplied as parameters or properties rather than hard-coded inside the class.
