I'm glad we got the chance to get hands
on experience with this powerful pattern.
0:00
You will see it in use all over the place,
especially now that you've seen it,
0:04
both in its Java standard form and its
looser interpretations of the same idea.
0:08
I hope that seeing these different
approaches helped drive home the fact
0:12
that these patterns are in fact
suggestions, much like a recipe.
0:15
There's a defined, drawn out approach.
0:19
However, there are many different ways of
0:20
implementing patterns to
achieve the same goal.
0:22
And that goal is to help provide
the loose coupling that we saw.
0:24
That loose coupling is the lack of
knowledge between the observers
0:28
themselves, and the object that is being
observed, the subject or the observable.
0:31
I hope you felt how extensible your
code got by employing this pattern and
0:36
are starting to see your spidey
sense tingle when it should be used.
0:40
I'm very interested in your feedback
on what you thought of this approach to
0:44
exploring patterns.
0:47
If you'd like to see more like this,
0:49
I will be observing
the reviews on these videos.
0:50
Please check the teacher's notes on how
to request more specific patterns and
0:53
how to make your voice
heard on what you and
0:56
your fellow students would
like to see us cover.
0:59
Until next time, thanks so much for
hanging out, and we'll see you real soon.
