60. What is dependency Injection?
Classes often require references to other classes. For example, a Train class might need a reference to an Engine class. These required classes are called dependencies, and in this example, the Train class is dependent on having an instance of the Engine class to run.
Dependency injection is a programming technique that makes a class independent of its dependencies. This is achieved by decoupling the usage of an object from its creation. Dependency injection allows the creation of dependent objects outside of a class, and it provides those objects to a class in different ways. The user can move the creation and binding of the dependent objects outside of the class that depends on them, using dependency injection.
