 These are the complex problems that Dependency Injection solves.

 In terms of Dependency Injection, this means loosening our dependencies by controlling and instantiating them elsewhere in the system.

 no more refactoring would be required as we can ensure that the adapter follows the contract set by the interface.

 What this means in practice is that you can write application code that is as clean and de-coupled as the framework it is built on.
