SampleFinal Q7a)

[lydial92]

Hi,
in the Sample Final Solution, an AccommodationManager class and
UserManager class are created to remove/get user and accommodation.
However, can't we just include those methods in WhereNotToStay? Why do
we have to create extra Manager classes for them? Is it because we
want the classes to be more cohesive in which they focus on their
specific responsibilities ?

Thanks~

Right. We now have one class for managing accommodations and another to manage users - these are two different aspects of the system. If we merged these responsibilities into a single class, the resulting class would have poor cohesion.
