design refactoring
The Date class currently
handles the job of seeing
if a particular event
is appropriate for a
particular date.
FirstDate
# validateEvent(event : Event)
:boolean

Your design at the moment makes it hard work to add events, change event names,
and even deal with additional dates. Take a look at the current design and mark up
what changes you’d make to apply the single responsibility principle to the iSwoon
design (and in the process, make it easier to add new events and dates).
Date
+ seeMovie() :void
+ goToRestaurant() :void
+ orderFlowers() :void
+ goOnDate() :boolean
# validateEvent(event : Event):boolean
SecondDate
# validateEvent(event : Event)
:boolean
All of the logic in these methods
needs to be updated every time you
add a new type of event.

There’s a method
for each type of
event that can be
added to a date.
ThirdDate
# validateEvent(event : Event)
:boolean
