Day by day, I am learning (cum refreshing my technical knowledge) more and more from your PHENOMENAL TH-cam teachings even after 20+ years of my experience in Java world. Inspired. Your teachings with EXCELLENT MATERIALS cum PRESENTATION (both VISUALS and VOICEOVER) gives me the crystal clear understanding and revision of all these concepts in a CRISP cum CRYSTAL CLEAR manner. Your work is the seed for a lot of the needy people who are eager to learn these topics. Thanks a lot again and hats off to your attitude of sharing your knowledge in the HIGH QUALITY STANDARDS manner.
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.
Being foodie I guess this was easy for me to watch video fully till end as examples showed in this video is so real and relate to food 😅. Loved it. No option but subscribing just now 😊😊
Dependency Injection is important on the one side, but also frustrating on the other side. You can reduce your instances and code that is a good point. But in the case of error search it is not so funny. You can not search for the uses of the instance. So you have to search in the code. yes you can use the file search, but if the code is hidden in a library than it is not so easy. But that's the business. We make all easier with frameworks, but if something doesn't work as it should, it is hard work. You have to understand the framework if you stuck on something.
Presumably around 1:48. Since When Food was instantiated by burger and pizza private Food burger; private Food pizza; I was also confused about this concept before when I started learning OOP, since we know that interfaces can't be instantiated. But since Food was implemented by Burger and Pizza Class, what the declaration there doing is referring to an object that implements the interface by the type of the interface. Yeah, took me almost 2 weeks to accept that idea and get used to it. Hahaha
The most simple and clear explanation I found so far!
I watched many videos on dependency injection and this is the most clear and easy to understand one! Thanks!
2:01 wow i had no clue these solutions were bad since this is how we were taught in school. Im glad i watched this video
Finally someone showing valid examples. Thanks!
This this the most precise and clear video on abstraction, dependency injection I've ever seen. Simple and concise!

Thanks a lot for the kind words and support
Thank for saying what I have always felt. It is easy to make things complex, it is difficult to make things simple.
best explanation ever. thank you
Thank you so much, after seeing how simple this is now I can't un-see it.
wasted several months trying to get that shit till it just clicked
you explained it extremely well 👏you've left me no choice, now I have to subscribe 😂
Thanks for the support! Glad I could help :)
goated video, DI was never made so clear
Amazing explanation. Best I've seen so far
my 8 years old son, watching this video with me wanted to say this topic is way to complicated 😀😃🙂 but I love the way you explained it
Glad you loved it! If at 8 yo he is watching this, can't wait to see where he'll be at in 10 years, way to go!
should have watched before I started learning Spring 🤣
Well, now you did :P
superb video that is absolutely comprehensible! Thank you!
You got new subscriber .Great explanation without waste of time.
I have java exam tomorrow thanks man this cleared my understanding
finllay understand this IOC concept thanks alot
All I need is this video. I have to subscribe 👏 Amazing man
Thanks for the support :)
perfection!
Tnx, this video really helped me understand dependency injection
Perfect explanation. Thanks a lot!
Very clear sound
A million thanks! Alas i understood dependency injection :)

you should have mentioned about autowired too. good video btw.
Great video, thank you !
Could you do a video on how to create custom annotations and use them as dependency injections ?
Check out these videos: th-cam.com/video/Vbc1YHVWFhg/w-d-xo.html & th-cam.com/video/ja4is9oq37k/w-d-xo.html
@@geekific Thank you, this helped a lot 🙏
Now we are in functional programming paradigm. please share us more info about the Dependency injection in functional programming
Nicely explained ! Ty man
Amazing video! Thank you!
so awesome, thank you

cool cool cool. now one more about mocking please )
i'm sorry for non english speaking people since this video explains di really good!
wowww
How can you instantiate an interface?
Where did we do that?
Presumably around 1:48.
Since When Food was instantiated by burger and pizza
private Food burger;
private Food pizza;
I was also confused about this concept before when I started learning OOP, since we know that interfaces can't be instantiated. But since Food was implemented by Burger and Pizza Class, what the declaration there doing is referring to an object that implements the interface by the type of the interface.
Yeah, took me almost 2 weeks to accept that idea and get used to it. Hahaha
02:04 Why is Bad solutions??
I understand jajja, It is because that class depend directly(hard-dependency)
I think its unfair that u dont mention generic at 1:50
I get what you are saying, but I really wanted the video to fully focus on DI and avoid confusing ppl!
