    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. 1:01
