Java Functional Programming | Full Course

Functions are fun. Do you want to turn 20 lines of code into 5, perhaps. Well then you should learn what Java has to offer when it comes to functional programming.

In this course you will learn the power of Java Functional Interfaces and how they can be used to create powerful statements and design patterns.

The beauty of Functional Interfaces is when they are combined with Streams, allowing you to write declarative code.

I have been applying functional programming by just looking up Stack overflow and other materials online in my code but I have never really understood it until this day. Great tutorial!

[bediaguvenc]

This is an amazing course that I have seen on Functional Programming Java! Finally, I got the main concept. The way your teaching style is amazing.Thank you for all your effort and for giving away your knowledge all over the world. Thank you, Nelson!

I already read some tutorials about this subject but after following this 2 hours video it really started to make more sense. Other than some other free tutos, this guy has a calm, clear and relaxing voice which makes it more easy to follow and keep concentrated. I look forward to the Security tutorial which I will follow next!

[GuitarreroDaniel]

Nelson, I can't thank you enough for all your videos, I've been watching many of your videos and I have learned a lot. I can say that you are my fav Java teacher and you truly honor the word "Amigo"!

I just finished this course and it was very nice! Thanks a lot. This combiner pattern looks a lot like builder pattern and yes i love it.

[DeGoya]

Barakallahu feek brother, your videos about spring boot helped me a lot, since there're not so many on youtube

[ShubhamSingh-]

I admire you. Really appreciate your work to educate others especially for free. Person like you do lot for the community. Please keep this going, never stop. God bless you.

You are awesome sir! Providing such content at free of cost no words for this

[yjdhzmg]

Let me express my thanks to you and to the significant effort you have put into these courses. I have learned a lot from you, and will continue doing so. Cheers, and keep up the good work! :)

[An-Engineered-Journey]

I love your tutorials man! I recently got a job at a tech company and the entire codebase uses functional programming which I wasn’t used to using at my last company. You have been so helpful in learning and understanding! Thank you so much!

[sebastiandrozd]

Started studying for my OCP and this is EXACTLY what i needed in my life right now. Thank you so much sir!!!

[alexandresantos]

Thank you very much! I'm certified in Java 7. But I was thinking of updating my certification, and my skills in Java and you are the best teacher that I found for it. You explain very well and in a very easy way.

[Hubertoom]

Great stuff man!
You had to work hard under this course. Thank you a lot, it was useful and very clear explained!

[Persephoneia]

Dude you're awesome. I've struggled understanding a lot of this despite having a job being a Java dev. No one ever explained it in a way I understood. Finally get it.

[terrynguessan]

I am new to Java programming. I watch several video tutorials before yours. The difference is obvious: your explanations are clear and help understand the why. Great job!!!

[VivekYadav-vklh]

An hour into the course and I couldn't stop myself from writing...

this is an awesome tutorial
Functional Interfaces do not scare me anymore.

thank you so much for this course

[imlearninghelppls]

After jumping from tutorial to tutorial trying to understand Lambdas and all this functional interface stuff, I finally found someone who could guide me through the very basics of this important programming paradigm. Thanks a lot!!!

[igoralessandrozelaya]

Amigo you have the best courses and guides, thank you for sharing this knowledge with us.

[ryanunknown]

Relatively short, clear, concise and most importantly practical examples. Thanks brother.

[mithunrocker]

Thank you so much for this wonderful tutorial. I was searching for a detailed explanation of how to use functional interfaces in java 8 and i m glad that i landed up here.
