After studying books and web tutorials, it was unclear as to how things were connected and operated. I felt mentally lost. After viewing this video one time, things were 90% clearer. Truly much thanks for your work here. And I thank the creator for you.

This was a really great explanation! I've watched several videos and attended a classroom lecture on this subject recently but I was still a little fuzzy on how to implement it correctly. After watching your video 2 or 3 times and trying out my own version of the implementation, I feel much more confident about this design pattern. Thanks for the hard work!

You don't need Subject attribute in Customer class :)

Hello there! Just have a question...I suppose we can do away with the getters as we don't need them...we are using just the setters. I did and it worked so was just curious if the getters are needed at all. Cheers!

Nice video. Why do you put this Subject subject in Customer class? I've tryed it also without it and it works.
I mean.. does it need to be there for other example or we don't need it at all? :)
Thanks!
