Java Functional Programming | Full Course
Ғылым және технология
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!

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

Oh 😯 thank you 😊
You are awesome sir! Providing such content at free of cost is..... no words for this
Great stuff man! You had to work hard under this course. Thank you a lot, it was useful and very clear explained!
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! :)
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.
This is gold! It blows me away that this is all free!
Thanks so much for making this! Really useful and at the perfect pace for someone who knows basic Java but wants to learn something new.
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.
Started studying for my OCP and this is EXACTLY what i needed in my life right now. Thank you so much sir!!!

wow I am so glad for you
Relatively short, clear, concise and most importantly practical examples. Thanks brother.
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!!!
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!!!
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.
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!

what is the actual benefit of using functional programming? why should we use it?
Everything explained in a very simple language. Exceptional... Thank you.
This is the best tutorial about Java Funcitional Programming, thank a lottt!
This was an excellent video. Crystal clear on Functional programming! :) Thank you so much Nelson. Might I suggest to post a Java design patterns video (Creational, Structural and Behavioral) in your own awesome way, that would be really helpful!!!
Excellent Introduction! I was able to follow, easily, to the end and found it extremely useful.
Love this tutorial man thanks for everything!
JazakAllah Khair for making these amazing resources! I have benefited so much from your examples and clear explanations! InshaAllah may you have continued success on this channel and professional endeavors!
Saludos desde México, este es el curso de programación funcional más genial que eh visto. Muchas gracias por el tiempo que te tomas en enseñar gracias .

Dude, you are great teacher! In 2 hours I understood everything without banging my head on keyboard 😱 Thank you very much!🔥🔥🔥🔥
Great tutorial, I found it very interesting and for me with your examples very easy to follow. You gave us a good stack of fantastic examples.
Thanks a lot for the course mate, really good stuff in there !
Thank you so much! I Really appreciate your work and you explain all perfectly. I'm also learning English and sometimes is dificult to me to understand people when they talk, but you express yourself very clearly and you are understood very well.
Well thought out and delivered. I am impressed amigo! Functional Programming in Java Made Easy by your talk.
THIS IS AMAZING! Please keep doing awesome courses like this one!

Nice course amigo! Greetings from Mexico. You should consider do a course about handy design patterns, I mean, the ones that you used the most on your daily job. The combinator one in this course was awesome.
Thank You, Nelson for the effort You are making to create this tutorials !
Thanks For making video on Functional Programming, It is so easy to understand. It is the most easy way you have explained .. Thanks a lot again
Great course, I read about functions everywhere and supplier, predicate functions were just a soup at the end. But after this course i am confident and know how, where and when to use. Thank you very much.
Amazing. Made me understand more about those arrows function in js
The way you explain is amazing and very easy to grasp and implement. Please keep doing such videos which helps a lot. THanks a lot 🙂
Your way of speaking is very good, stressing on important points so that the focus shifts to them.. very nice video !!!
great tutorial. Your voice is so calm which makes us focus and concentrate without getting bored.
that is a great tutorial. thank you, Nelson. i have found one tiny little improvement. In the beginning you say, that it basically doesn't matter, what Java-Version you use, as long as it's above Version 7, which is correct. But, If you are working with Java 8 and you want to follow along by writing down your examples, you'll recognize, that in chapter "Supplier" you use the List.of()-Method, which isn't available in Java 8. It's no problem for someone who has at least a basic understanding of Java, but for total newbies it could get confusing at that point. The Rest is fully usable with Java8. Thank you very much for your work.

Yup. I've substituted that with Arrays.asList() for the beginning (haven't gotten to Suppliers yet, maybe it'll work there too?)

That Combinator pattern part is really awesome...Cheers
Man you could even teach Haskell that way! Thank you for that wonderful tutorial. Could you do another video applying those concepts together in a larger sample project? For me it's difficult to get the feeling when it's time to use this and that. To combine many of those methods together is also something that requires a great amount of functional thinking.
Your way of teaching is on another level, keep it up!
This was a very good tutorial. Wish the combinator pattern was further elaborated with real world examples along with other design patterns used in Functional Programming specific to Java.
Great workshop. I enjoyed this thoroughly. Bravo.
I really enjoyed this video. I've been playing with lambdas but this is something slightly different. Thank You for so clear explanation. I will rewrite some of my simple apply to convert them into Functional versions.
I would hit the like button a thousand times if I could, this course is extremely helpful if you want to learn Java Functional Programming!!! Thank you Nelson for the video and I'm already a subscriber and will most definetely watch your other courses! .. and I thank everybody that did leave a positive comment because that led me to watch this video entirely.
thank you for this awesome tutorial finally I do understand functional programming in java
The course is great, thank you to share your knowledge!

This is really great Amigo....thanks....please keep doing what u r doing....U're helping people who can not purchase these kinds of online courses.....thanks
This is a really awesome course. Thank you!
It's a really nice tutorial .easy way to learn functional programming.All tutorials provided by you really helps a lot.expecting one video on java multithreading in depth .
I really like the way you present the material. Very nice!
Thanks a lot for your course!! and you speak slowly as I can understand (Brazillian that learning english and Java) the functional style really make my eyes shiny, i saw that you made an great full java course in a year ago, my dream is found an SpringBoot Java course wth spring but using functional style on every situation that is possible.
You have amazing teaching skills, Great Tutorial:) Thanks
