i learn more from ur 30 - 40 mins than my 2 hour lectures
This series is like godly for interview preps.
I think yours are the only videos on RUclips for learning Design patterns thoroughly without even reading anything, really thankful for that and please never stop making videos.
You’re passion is infectious. Hope you keep this going .
Hi Christopher, Thanks for making such a wonderful videos on design patterns. I just come across your videos while searching for design patterns in youtube. I have gone through all of your videos on design patterns. I say these are simply excellent. Keep up the pace. Expecting all GOF design patterns through your videos.
+santosh ganji Solid. I'm glad to hear. About all the GOF patterns, I've been thinking about whether I should indeed cover all of them. I was intending to only do the ones in Head First but since the videos have been quite well received I might make a video for the remaining patterns in the GOF book. Thanks for commenting! And thanks for watching :)
@@ChristopherOkhravi 2020 and I share the same sentiment
You probably dont give a shit but does anyone know a trick to get back into an instagram account??
I was stupid forgot the account password. I would love any tricks you can give me!
@Theodore Braxton instablaster :)
@Jon Roland I really appreciate your reply. I found the site thru google and Im waiting for the hacking stuff now.
Takes a while so I will reply here later when my account password hopefully is recovered.
Oh, man, finally a dyed in the wool bona fide natural born teacher!!! If there were teachers like these around when I was a kid I would have paid attention first time around. But ... they spread the info out over a complete year that it took mr Okhravi less than half an hour to explain. Well, I ain't dead yet so I can learn this now instead! :D
Thank you for the great tutorials. You put so much effort on this and I should say that you made it crystal clear. Please continue this series and keep sharing with us your knowledge.
Thank you, Christopher, these are honestly the best design pattern videos I have seen and help me to really understand them. I look forward to the next video :)
+Ali Morrison Thanks! I'm glad to hear the content is valuable. Next coming soon :)
My god.. that transformer vs the plug difference to explain the difference b/w adapter and decorator is amazing! This would remain with me forever now. Thanks Chris!
I like how you teach man, it is very clear and simple to understand, and I appreciate all of the efforts you are putting.
You are amazing Christopher. So much dedication and passion. You actually created desire to learn and dive into these concepts. Thanks a lot.
Before you, learning the design patterns was absolutely tough for me, but after watching your great and subjective videos, everything has changed; TADA. Again the best adapter explanation I have ever seen.Thank you man.
Your videos are one of the few things I cant wait. Thank you!
+Olaf Olafski Haha thank you I'm glad to hear :)
Thank you Christopher for making these videos. These are the best videos that I ever came across on design patterns. I have watched all the videos and eagerly waiting for next one...
Dina videos är dom absolut bästa jag har sett på länge. Sättet du förklarar på är extremt pedagogiskt! Tack för att du har gjort dom här videorna!
My friend, you are one of the most thorough teacher of these topics that I have come across.
Thank you for this video!
Excellent editing, making your videos very fluid and easy to digest! Great videos!
Great video, i'm watching all of them and always looking forward for the next one. I manipulated in the past, when working on android projects, a thing they called a List Adapter that would interface together a collection of POD/primitive data objects and a collection of graphical/UI objects. At the time i wasn't really digging into those design patterns thing but now thanks to you I have a better understanding of what this adapter did.
Thank you Christopher, for recording the whole discussion, instead of making lectures. The videos and in super headfirst manner and I am able to focus and grasp the concepts and rationale behind these patterns. And most importantly I learnt from you on how to read a technical book and present our own interpretation. 👍
Amazing videos mate - loved the transition at 4:14 :P
:D
i really like how you always repeat things, i find it really difficult to focus on lectures and spoken word in general but with your videos i never lose track
The best explanation of design patterns I have come across on the internet. Great work man, you got a new subscriber! :)
I really enjoy your explanations on design patterns, it helps me a lot in my OOAD class 💙
Just want to say, i love the way teaching us 😉.
Christopher, you always say you don’t know this you don’t know that, yet you explain it very understandably. :) Thank you!
I had an exposition in university about this design pattern yesterday. You taught me how to explain this in a way that people can understand it, and I'm really thankful for that. Happy holidays Christopher :)
I’m humbled and really glad to hear that. Congrats on the success! And happy holidays to you too :)
You are very good at explaining how design patterns work! Love it!
Love the practical examples that you use to demonstrate the design pattern! Thanks for the effort you're putting into this...
Great video again. Whenever I try to explain this to anyone, I typically try to give an example where I'm trying to save some entity to a database. Then I explain the database may change but should not really affect the modelling of our program.
Thank you Christopher for making usch wonderful and energetic videos.
I truly wish that more lecturers can teach from the perspective of students, just like you do! I pay a ton in tuition but sometimes just don't get much digestible knowledge in return. There are professors that don't even bother to tailor the publicly available slides to their actual need, let along writing notes on board. They just read thru or fly thru some slide and give random thoughts. While this might work for advanced class, it's absolutely a nightmare for any introductory course. Sir you deserve a larger platform, and I wish you all the best!
Love the explanation. Quick and easy to understand!
Thanks a lot for ur effort on these videos. I have watched all patterns videos. Every programmer should watch them.
Thanks Christopher, the pedagogy is super good and it helps a lot after going through the books.
Hi Christopher,
I was going through head first book, and got confused with examples. But you explained those examples very well.
Thanks !!
Wow. I now understand the Adapter pattern. Very thorough explanation. Glad I found this video!
Yet another great video
The series is incredibly clear, Thanks a lot
Waiting for the next one
Thanks! And thanks for following the series. Next is on its way :)
great work!!! you inspire me for my upcoming bachelor thesis - thank you, so helpful!
I barely comment to youtube videos but i was compelled to write to this one. That was such a nice example and explanation. Your energy definitely made it a lot easier to watch as well. Thanks
Great explanation! Thanks a lot, I will definitely check out more of your videos!
Thank you so much for this playlist, I highly appreciate your hard work in creating lectures
I love that way of studing. It's fun, and you get me knowledge in easier way. Thanks a lot man!
The way you simplify and explain it is extremely commendable. I am preparing for an interview after a break in my career . On searching for relevant videos, yours is the best I would say, Thanks a lot. You bring in so much clarity by explaining it with simplest possible examples . Great teaching.. Thanks a lot. Could not resist appreciating your effort. I am pausing the video in the middle and typing this. Great job sir.
I have both design books and have been lacking the time to thoroughly go through them, so thank u!!!
+Christian M Solid. Makes me glad to hear that the videos work as a complement. Thanks for sharing and for watching :)
thanks a lot Christopher!! you're amazing!!
Thank you for these videos Christopher.
This is super incredible to learn design principles. I’m really happy I found this video
Man u you are wonderful. Wish every single teacher is like you. Thank for you for these golden content

Love the transitions in this one :D But really, this videos are very easy to understand and have a good structure! love It!!
Thanks Chris. I really love these videos.
Thanks for letting me know. And thanks for watching and sticking around :)
Man…you did such a great job!
I just want to see more videos from you!
My brain exploded as I finally understood the differences. You are the best!
This video needs more views, very helpful!
This is better than the "Best Selling" Udemy course on Design Patterns. I know cuz I bought it and now regretting.
Well for not a good "reader" like me, your videos has been so clear and understanding. thanks a ton bro. keep it going.
Probably the best example of the Adapter Pattern I've seen
Thanks for sharing your awesome knowledge.
Another great explanation of a design pattern. Enjoy your youtube videos - these and code-walks.
Thanks! And thank you for the code walks shoutout :)
Thanks Christopher. It is really helpful.
Thanks for letting me know. And thanks for watching :)
Hi Christopher
Another great video explaining the pattern! Thank you so much for sharing!
I wanted to point out more about using the Adapter pattern for an external library.
It's definitely a good idea to encapsulate all your external DAO calls in the adapter pattern, like calling a database or an external service.
Another reason is Exception handling.
For whatever reason you have defined your own exception type hierarchy (transient or permanent exceptions) in your code base. And you want to translate the exceptions thrown by your external dependency.
Adapter pattern is good for that because you can wrap the call to adaptee.speceficRequest() in a try{} catch{} and re-throw exceptions of your own type.
One useful point of rethrowing exceptions of your own type is to have different retry policies for different kind of exceptions.
Thanks again for sharing the video!
Very clear and concise explanation with engaging teaching style!
Watched whole video, guess I was hypnotyzed by peculiar patterns on your t-shirt 😁
Very helpful, thanks Christopher!
Thank you for the video Christopher.
Best deign pattern videos out there ! Thanks Christopher
Thatnks a lot Christopher for making these videos, you are explaining very well, easy to understand, I am not referring any books. your videos are enough.. .:)
Hi Christopher. This has been the best explanation I've seen. Immediately liked the video and subscribed to your channel! You earned yourself a new fan 😁
Christopher: I've just found you....and I have to say that it is the best explanation that I saw about design patterns. I'll see other videos. Thanks from Argentina! Martin!
You rock on all your classes, man
Cool stuff bro, keep doing 'em. What I would like to see is the adapter pattern explained in terms of how to, for example, draw different tree-views based on a composite pattern. Maybe you'll get there later, just started watching.
Amazing!!! May god bless you for these tutorials!!!
I normally don't comment. But I wanted to say thank you for the explanation! Really a good way to understand!
Thanks for that video. Very clear explanation.
Great explanation. Thank you
what a presentation man! amazed
I really like your explanation of the topics! Go on :D
Thanks! I appreciate the motivation :) Glad to have you following. Thanks for watching :)
Hi Christopher thanks so much for this really intuitive series😄. Just wanted to ask why can't we create an object of adaptee in Client itself and call the specificRequest() method?
Loved the way you teach or make videos. Also love ur cat too !
Brilliant. Thank you so much!
Awesome videos!! I was waiting since long for such videos..Simply Excellent Work :) . Please keep on posting.
Thanks for such a good video..
very good explanation thank you Christopher.
your videos are awesome! keep up the good work man.
Awesome explanation
Another great job! Keep it up Christopher!
Thanks! And thanks for sticking around :)
Thanks for your video, as always!!!
This should be the first chapter of the book, it explains composition, delegation, asociation in a very simple way.
Very good point!
Very nice video! I'm kinda new with all this stuff and this video helped a lot!
waw you are from Sweden...fantastic explanation. Tack för de här underbara videon
A good example, in scientific computing where parallel computing is required, an adapter could be used to wrap/hide MP or/and MPI. That also simplify the interface of such external libraries.
Very nice video! Well explained!
keep doing the great work, God bless you
Very usefull. Thanks for the effort Christopher!!
best design pattern explanation on youtube, thank you sir
Hello Chris, again awesome video, I did not know that adapter pattern was also known as a wrapper, but thank you for mentioning that at the beginning of the video, it makes totally sense to be called like that
Hi! Thanks a lot! Best material on this topic! And i must admit video style is cooler and cooler and funnier in a good way! :) thanks thanks thanks!
Hi Christopher, Thank you very much for making the excellent videos on design pattern and your explanation is damn good. thanks again
Beautiful. Thanks!
Thank you so much for such an amazing tutorial.
