I haven't seen any other tutorial that has described this with such simplicity and beauty!! Really great work man!

Trust me this channel is best for industry people.....the sad part is we do not get to see any more videos from this channel.......i would request the creator to at-least think for a membership based subscription

I don't have words to describe you boss awsome bro

I have read lot of books and watched so many videos on multi threading, no one explained in this manner. Great work. Thanks for the content.

DONE thanks 1:17 callable is used when you want to return a value from a thread (normal thread doesn’t return anything) Implementing call method that returns ReturnType Callable returns a Future that is a placeholder for the real value. Doing future.get() is blocking if the task is not completed 2:50 visualization We can chain methods together (instead of blocking with get() we say thenApply(...) and chain calls asynchronously See chaining from 5:59 12:50 can perform the chained asynchronous operations on the same thread or provide a different thread pool (executor service) for each operation (some operations might be cpu intensive some io, so we want to use different threadpool) 17:00 we don’t have to specify an executor to completable future, it uses forkjoinpool internally Todo continue from 1:17

Whenever I want to remember something about java concurrency, I go and watch your videos, Great job

The most practical video I've ever seen on CompletableFuture

Finally I understood! Thank you!!

This video has shown me true power of CompletableFuture

came back it to again after few years. still blows my mind how simply OP has explained the concepts.

Beautifully explained. You make everything very simple yet covering all thats relevant to the context. Please keep up the good work that benefits millions like us.

This is 1 video which explained me Future vs Callable Future clearly out of many other videos

Your explanations are truly amazing and crystal clear, hats off and thanks a lot for such a great content.

Terse, succinct, precise, informative, amazing, clear, .... running out of words to describe. Thank you so much for the video series

why this channel stopped. This is the best source for concurrency topics.

Sir your explaination is awesome. I haven't see this type of deep explaination from other tutorials

Thank you for the session. A few questions please: ONE - what if instead of creating a loop of 1:100 (i) you fetched 100 product ids, how would you revise your code to process 100 orders in parallel? TWO : what if you needed a receipt at the end of each order processing (success or failure) , how would you aggregate results of each thread without blocking and print the final 100 line status receipt from main thread?

Hi Deepak, Your doing a excellent job of covering the most complex topic of Java threads & concurrency on your channel by providing detailed insight & explanation on each feature in simple and clear manner with hands on code. Keep it up.👍

The way you explain complex things in simple flow with sharp voice makes it impossible to take break from learning :) Great work Sir!

Whenever I think of concurrency, I know which YT channel to look up. 🙂❤

Too concise and crisp 👍

Would be great if you had a series on reactive programming. Good complement to your discussion on completablefutures

Hello sir, I am big fan of your teaching skill. You explain tough topics in very easy way. I request you to please make some tutorials on RxJava. Thank you so much for all your effort.

Really nice 👌.. I have never seen this type of videos related to concurrent package...Awesome explanation with simple examples ...tq so much....

i can't think of a better explanation than this . Amazingly explained. thank you

super precise and super cool..thanks to you sir.

I tried to write some good comment for your video session but I can't have word to write.... you are simply very very amazing Sir.... clear all doubt..... never seen this please keep on posting video session.....we are excited to see your new upcoming video session....

Teaching is an art and you have mastered it . Respect ++ Sir !

Very nicely explained. Finally got clear on the concept of CompletableFuture. Thanks for this video.

Thanks.. you really made this complex thing easy!!!

Crystal clear. You are really have the knack of teaching

salute you from heart.. no words i have !

Watch it twice guys, after second time everything is clear. Thanks for the video!

Have to say, very well explained. Keep creating the good work.💪

Amazing work! Thanks a lot for such a wonderful video. I went through 4, 5 videos from your channel. You have excellent command over teaching in all aspects: mentioning problem statement, explaining with diagram, providing solution and need of each line why it's been used with available relevant alternatives, pros and cons. On top of this your speed and tone is perfect for learner. Superb audio, video, presentation quality as well. Thanks a ton! God bless you.

Brilliant video. A lot of my confusions got resolved through this video. I will subscribe to you because I find learning with you very enriching. Please keep creating more videos like this :) Also for completablefuture if you can include collecting multiple futures through .get .all etc... It'll be complete

Another beautiful and clearly explained video :) Haven't seen any new videos from you :( Please continue making such videos, it really helps.

Very nice explanation, thanks a lot

This is the second video I watched from your channel and you straight away became one of the best Java youtube channels I'll follow and recommend others to follow as well. Thanks a lot for this super easy explanation!

You are doing Great service, Dude

Beautiful. "Possibly Asynchronous", I have never heard anyone said that. 👍

Absolutely brilliant !! I have seen many videos on completableFuture , but this was the best one. what clarity man. Brilliant !!

By watching this I have become a big fan of your tutorial thanks lot ..

Fantastic job man! God bless you. Please do a video on RxJava. Nobody will be able to explain it like you do.

Very composed and clear explanation with practical examples. Great work!!

Dude, where were you all this time? videos are precise, exact and crisp.

The thread pool and tasks graph is really nice.

Wow superb explanation ..!

You are awesome man.. i just can't explain how much you helping people to understand deep concepts in easy way. I request you to make series of RxJava ..

Very very awesome. I now fully understand.

You are awesome! Please keep posting videos don't stop. No one explained threads the way you do..

Best explanation I have encountered, thanks so much!

Really simple and informative. Thanks for this video. I got to know all that I needed to know about CompletableFuture from here.

such a amazing teacher, hats off dear!!!

I could listen to your explanations all day...u make it so easy to understand...u deserve many more subscribers

Superb explanation

Such great understanding, I have become a fan. How did you learnt about all these ,you prefer documentation or books or videos? Knowing the answer to this will help me hit the foundational part missing in my learning. Great video though.

Really really superb explanation of complex topic to understand easy.

Please please continue video making😭😭..it's a GOLD

Good Explanation on Completable Future

10:47 I got unsettled watching those lambdas not being converted to method references :P Thanks for the great video Deepak!

Brilliant explanation mate.❤

You deserve more subscribers and views. Very clear and crisp and to the point.

Really great work man!

Neat and beautiful... Excellent!!

who is this guy ? I have seen very few people in internet explain java topics with such simplicity and cohesion

A great video that I came across to understand CompletableFuture. Keep it up man.

Thank you! Great and informative video! I don't understand why majority of tutorials(youtube, udemy) doesn't use diagrams or pictures when explaining it's much easier to understand and gives better understanding of all flow. But instead majority just types code and mumbles what that code does and for beginner it's hard to grasp.

liked the detailing

simple, easy, to the point, really excellent

I am interested to smash the like button..in a for loop 100 times in async mode :)

Awesome video with the perfect usecase

Very nice!

Awesome explanation Sir. Why are there 20+ down votes....?

Very well explained, You have long way to go....Subscribed already n waiting for other video’s....Thank You...

If only everything was explained with an example like you did, we would never not understand anything.

excellent.

Very well explained, than you!

Nice explanation. Very clear and the recording was also crisp

Great Explaination!!!
