What is DI or Dependecy Injection?

Dependency injection is a software design pattern where an object is given its dependencies(other objects it needs) from an external source, rather than creating itself.

There are three methods for injecting dependencies

• Constructor injection: Dependencies are provided through the class’s constructor.

• Setter injection: Dependencies are passed onto the class through public setter methods.

• Interface injection: A less common method in which depency is injected into the client through an interface that the client implements.
