If you’re a software developer or you’re studying a programming language, you may have heard of: Dependency Injection. Personally, at first, and I am pretty sure that you as well, thought that this must be a really hard concept. But I assure you that it’s just a fancy term used to represent a very easy concept, and that's what we intend to prove in this video!

Thank for saying what I have always felt. It is easy to make things complex, it is difficult to make things simple.

I watched many videos on dependency injection and this is the most clear and easy to understand one! Thanks!

@user-ed5cr8so7f Год назад

The most simple and clear explanation I found so far!

@alpugurkonca2575 Год назад

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!

Day by day, I am learning (cum refreshing my technical knowledge) more and more from your PHENOMENAL RU-vid 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.

@masterreif 10 месяцев назад

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.

Now we are in functional programming paradigm. please share us more info about the Dependency injection in functional programming

@sujithameriga7348 Год назад

How can you instantiate an interface?

@geekific Год назад

Where did we do that?

@abutohan Год назад

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
