Parallel and Asynchronous Programming with Streams and CompletableFuture with Venkat Subramaniam 

26:43 parallel() and sequential() the last one called wins. 43:40 forEachOrdered() 1:01:00 identical value for reduce operation. Here is my question, if the reduce operation always requires an identical value for initializing it, why doesn't Java omit the parameter? 1:05:00 How many threads should I create? 1:15:36 configuring number of threads JVM wide 1:34:27 CompletableFutures 1:38:10 Lesson from Javascript--Promise 1:39:22 Exception handling and functional programming are mutually exclusive. 1:47:00 Famous or popular functional interfaces; 2:00:47 Thread of execution. 2:12:11 Comparison of stream and completableFuture 2:17:44 Pipeline of completableFuture 2:27:44 Exceptionally 2:44:18 Succeed on timeout 2:53:32 Combine and compose

I will recommend this to anyone who is ever interested in understanding Streams and CompletableFutures in Java. It helped me immensely when I started working with Java in my new job after 5 years of Python. Wonderful presentation!

This guy has to be on something to be able to explain it so flawlessly. Thanks for the video man !

I love this guy's talks. Undoubtedly the best videos on Java.

Finished watching this video for three days . Was tough to analyse and digest it initially. U r my hero Venky brother ❤️

So well done, and very understandable. Venkat you are my Hero!!

This is the best video of CompletableFuture I have ever seen.

Always a pleasure to listen to Venkat!

I'm sharing this video to anyone I know who's ever made remarks about Java being stuck in the past! Venkat is such a great speaker - such a legend.

This is awesome talk. Venkat really tied down to all 3+ hours with very interesting talk

I wish i found this video when i was working with asynchronous functions in java

After watching this video, I found out I spent too much time to watch entertain videos, miss this kind of amazing learning videos, then I think I will do the master switch like in video

Watching all Venkat videos and reading all his posts 🙌

Thanks to venkat and devoxx. Venkat, you' have a wealth of knowledge that leaves me speechless every time. Your lessons are the best.

Amazing style, very intuitive! Didn’t realise how three hours flied 😊😊 I felt like watching a Netflix series with the same concentration.. mind blowing

Keep an eye on Project Loom, an addition to the Java VM for very lightweight user-mode threads (fibers) .

I have understood the difference between imperative and functional programming first time after listening to his talk :))

Amazing presentation! That was a great introduction to streams and CompletableFuture, easy to understand and follow despite the concepts being hard to grasp. I feel inspired to play around with it myself :D I’ll recommend this to anyone confused with those topics. Thanks a lot, Venkat and Devoxx for sharing it for free!

Hi sir Thank you so much for sharing intense knowledge on Compleatablefuture and streams.

Thanks @Devoxx team

"While you are debugging the code, you applied for another job- that's called concurrency!". "Synchronize and suffer model"... Omfg so true! That's exactly how it screwed developers' not only career but also life.

Just one line its awsome even after 10 years.

Venkat is the best! not even interested in java im watching the whole thing lol

amazing, it really covers all the concepts I am looking for to learn, not just the ones in titles, for the parts don't understand for me and you, can go further into it, love you

The software developer saying to his boss that the project "completedExceptionally" is a good one :)

This is so underrated.

Amazing I am getting addicted

Great teacher!

Thanks Venkat! What an awesome talk!

2:07:00 important 2:10:40 why to use thenRun

The Venkat jokes kill me 🤣😂😅 no no no we shouldn't understand quickly

Really nice video. However he really wanted to look like he doesn't need IDE, but after few hours of lecture he started making simple mistakes that every IDE would point out immediately.

I love your talks Venkat

amazing. Thank you very much Venkat

Venkat is like sivaji the bossss.!!!!!!!❤

Can you please upload classes on jvm architecture and working of jvm.

extremely helpful and interesting.

So valuable, if only i could like twice :)

Absolutely amazing talk

1:17:53 Result is not same in both cases.. notice last digits 22944E12 and 2295E12

Thanks venkat🙏🙏

Well done pandit ji

Awesome 👍

I love how hilarious he is. Very good lecture, professor. I could learn from hours and hours. I first met functional programming thanks to Haskell and I was amazed when I found out that Java had introduced to Java world a functional API. And I was even more surprised to see people using it in the marketplace. For example, in the Spring Framework you end up resorting to functional techniques all the time.

supa great, thx)

If I want to use map with parallel stream and I want to maintain order. In that case how is it possible ?

Which editor is this?

Excellent

Need to move records from one schema to another schema in db. how can we achieve using Multithreading ?

what is that editor he is using ?? btw great talk.

any idea which text editor he's using?

Just Awesome

Thanks man

Brahmin People are so Intelligent 🧠 , Venkat Is an example ❤

Just Wow!

impressive !

But I want to argue why did you choose such a complex example explaining parallell programming and asynch programming!

1:34:26

what is the text editor? looks transparent

nice talk

What ide are u using

best talk ever

Just ❤️

Here is a cheesy joke. Why was main so busy with 7. Well, because main was afraid of 7 as 789....

Might I add that the API in Java is a massacre compared to ECMAScript's version, and that is the nicest way I can express what was shown here without resolving to French

...and what took 12 minutes to run now took exactly TWELVE minutes to run.. haha 20:00

28:04 He was talking so fast..holy s.I thought it was fast forwarding

Great!! Does anybody know the IDE he used?

"...That's called concurrency" 12:55 ROFL!

Great, amazing talk! Very well carried and so dense in the good sense. Really deserves a full course. Thank you! Next time please leave the question part on the video, it must have been very good judging from the knowledgeable audience.

I still don't understand this part (2:21:16). Why does it return 2 instead of 5? The chain should already be extended by then, right? Why is it overwritten with the "thenAccept" instead?

This is gold. Lovvvveee the presentation and the way it was taught. Just perfectttt.. Thanks a tonne Venkat !

Explained in a Simple and practical way, this is the way an expert teaches, he makes complex things simple

Thanks Venkat! What an awesome talk!

Venkat the 🐐!!!!
