Functional Programming with Java 8 by Venkat Subramaniam

Java 8 is the most significant change to the language since it's introduction, surpassing changes seen in any of the previous versions. It is not merely syntactical change or addition of a few extra features, it's a paradigm shift. Come to this presentation to learn about the power and capabilities of functional programming using Java 8 and how to benefit from those when building Java applications.

This guy's own presentation style ... loved it

[SaiPavanPothuri]

I fell in love with functional programming after this talk 😍😍

The best explanation ever on functional programming 😊

[zerziszain]

Some important things to understand in this talk that I liked:
10:10 : What does it mean when we say functions are first class citizens?
11:30 : What are Pure functions? Why functions should be pure? Whats the benefit of that?
12:35 : A pure function shouldn't depend on anything that changes, but why? What happens if it depends on something that's mutable?
25:13 : What are method references? Here's how we reduce a simple println statement to a method reference deleting everything that's not required. Note that this is possible only because we're doing something very simple like just printing the input element.

33:45: Lambdas and Closures, from here upto the end is an excellent talk on closures and immutability.

36:45 : Why immutability is important for closures? What would happen if we use something mutable within the closure.

An excellence of explanation is here, thanks @Venkat Subramaniam

[ZackIOS]

As always, one of the best talks in devoxx's history :D Thank you!

[thalathotitharunprabhakar]

Thank you Venkat for the detailed presentation of functional programming style in Java.

[mkstudyjournal]

Well had listen this video multiple time...👍

[philsipad]

Very concise and informative. First time having to work with lambda expressions decades after learned it in college.

[ParthivPradhan-iqnc]

how can someone have so much clarity 👏

[hrs]

Really nice summary of a functional programming course

[thinker]

You are freaking awesome Venkat Sir. So glad to watch your video. You made this concept so simple.

[vijayschumi]

Best explanation on functional programming..good presentation skill to learn;)

[thlchmst]

This talk is freaking awesome and he is an amazing teacher.

[yogeshbhakhar]

Awsm content, clarity and above all presentation...Supeeeer. Thank you Venkat Sir and Devoxx.

[ManikanthVanka]

What is the code editor you have used ?

[MakeItStik]

Any idea where to find lazy evaluation of Lambda expression talk he pointed out in his presentation.

(Edited)
I found it. "Let's get Lazy" is the name of presentation.

So in this example there was 7 different ways to code the same thing in Java 8. It seems like the more versions that come out the more ways to do the same thing, that's one thing I don't particularly enjoy about Java.

[ramankpandita]

How did the List<Integer> appear all of a sudden @45:56 ?

[balanepalaiyathane]

Really great you may get better than this so far this is the very best

[thefunnybuddy]

Yeah I'm going to goto a different video.
Good video. Better than that last one I sa...

wait...
