Explicit Dependencies

It states that the classes and methods should explicitly require, via constructor or method parameters all the collaborating objects that are required for the function to work properly.

Classes with the implicit dependencies cost very high for the maintenance than the explicit dependencies.

Even, the implicit dependencies are difficult to test as they are tightly coupled to their collaborators.
