Dependency Injection, often abbreviated as DI, is a technique used in object-oriented programming to create objects and manage the dependencies between them. It's based on the principle of inversion of control, where the control is inverted from the object itself to a separate entity. This entity is responsible for creating and managing the dependencies of the object.

The concept of Dependency Injection has been around for decades but was formally introduced and named by Martin Fowler in 2004. It gained popularity in the software development community due to its benefits in managing dependencies, reducing coupling, and improving testability.
DI offers several advantages in object-oriented programming:
There are two primary types of Dependency Injection:
Various frameworks provide support for Dependency Injection in different programming languages. Some popular frameworks include:
Online courses provide a convenient and flexible way to learn about Dependency Injection. These courses offer a range of learning options for different skill levels and can help you develop a solid understanding of the concept.
Online courses typically cover topics such as:
Through video lectures, hands-on projects, assignments, and interactive labs, online courses provide an immersive learning experience that can help you master Dependency Injection.
Dependency Injection is a valuable technique in object-oriented programming that can enhance the design, testability, and maintainability of software applications. By using dependency injection frameworks, developers can streamline object creation, decouple dependencies, and improve the overall quality and flexibility of their code.
