Very nice!

4:25 The UML diagram is missing the has-a relationship from Composite class to Component internface.

This is just an amazing tutorial

you are super awesome

Wonderful and no other words I have to explain my thanks and gratitude for tour hard work brother. EXCELLENT - 1) materials, 2) way of teaching, 3) Presentation, 4) Attitude, 5) Command over concepts, 6) HARD WORK HATS OFF TO YOU MY BROTHER. THANKS a lot. If possible, Request to share more and more quality videos like these on all topics especially like Spring (Core) Framework, Spring Data, Spring Security, Core Java 17 topics and so on... My Wish: If possible to work with you technically and learn the "TECHNIQUE of LEARNING (that is, understanding new/any topics in a crystal clear manner)" from you. Thanks.

So with this pattern you can replace a single simple method that instanciate 10 different classes (implementing the same interface/abstract class) in a switch by 10 new creator classes to respect "Open to extension Close to modification" .... That's AMAZING ... What a great idea that's so much better now. LOL

So cool, at last. Thanks a lot!

pesu students thumbs up if here

Very clear and concise like a 'Use Case'😀. Thank you for sharing

you are the best my freind

you are amazing! Everything is explained so well. I can honestly say that I am learning more from you than my comp sci professor

Super helpful

That was the best explamnation so far! Thank you very much!

FUCK SOLID

Thank you

isn't this just a microkernel architecture pattern?

isn't this just our old friend encapsulation?

wowww

Factory Method scope is classified as class and Absrtact Factory scope as object. Can you please tell me , How it came into that conclusion?

What is the use of "private String data" field here? If i call the getInstance() function with some data string, it will not update the data field of the instance. The first getInstance() call will set the data value and it will never change again. What am I missing?

you have the best teaching skill among the youtubers i've watched , keep it up bro ....!

Really helpful

Sorry but why cant you make a list of INotifiers, and call by iteration, instead of creating this ceremonial boilerplate?

Multiplicity wasn't explained very well. Allow me to clarify: The multiplicity attached to each class indicates how many instances of that class can be aggregated-by/composed-by/associated-with a *single* object of the other class. For example, the relationship @4:53 says two things: (1) "0...N BankAccount(s) can be aggregated by each single Customer object" and (2) "There is exactly 1 Customer object for each single BankAccount object". Similarly, @7:23 (1) "0...N BankEvent is associated with a single Customer object (i.e., a Customer can attend 0 or more BankEvents)" and (2) "0...N Customer is associated with a single BankEvent (i.e., Each BankEvent can have 0 or more Customer(s))"

can pls do share tools you use for your tutorial creation, looks great

Thank you for your such detailed Information It is something I was looking for.

Can't figure what does the "pizza.SetToppings" mean. or, more specifically what is the " .SetWhatever ". I know what it should do, but it does not work, it says that it needs to be declared previously, but where should I declare it, how can I change that string while the object is being made? My code gives "null" where all the toppings, sauce and crust types should be. Plz send help!

Hey man, checked a few of your videos, they're great, keep it up, understood a lot of concepts thanks to your detailed explanations

great video just one question, when doing the Customer id example, if we are already using the synchronized method to increment id we dont need to use volatile keyword right? l

but this question is about arrays and video is about linked list

Nice one

How do you insert, remove or reorder handlers dynamically? Each handler only has a reference to the next one

In terms of suggestions for future videos: 1) algorithms topic - since you have a playlist of well known topic like "graphs", then maybe you can also do the infamous "dynamic programming" playlist? :D 2) Java topic, maybe you can do a demo how to secure a web app e.g. with spring security?

Very helpful thank you!!

Great video! I was wondering if it would be possible to use the Composite pattern here? We can have that Whatsapp and Email notifications implement the Notifier interface and then have compositeApps which can include any platform (Whatsapp, email, facebook, etc). Thanks in advance!
