What this means is simple terms is that when we want to use/instantiate the ``DefaultUserServiceComponent``, we need to use the with keyword and specify an implementation of the ``UserRepositoryComponent``, which in this case would be ``UserRepositoryJPAComponent``.

This will be shown when we wire the whole thing together in the next step. * Hopefully the rest of the code should be pretty clear, we’re simply defining a class which implements the UserServiceComponent and defines implementations for the two methods – simply delegating the calls to the two classes defined in the ``UserRepositoryComponent`` which we now have access to thanks to the self-type annotation #Wiring everything up
