Thank you for creating contents in english as well. I am one of the supporters who also share your videos of certain topics when I am asked where to prepare. Please make videos in english (as well as Hindi). Don't forget your english-speaker followers!

Cheers

Really needed this with virtual thread this is a end to end multithread explanation

10:37 Aren't both runnable interface implementations, lambda only works with functional interfaces, when you give lambda directly inside new Thread() it's actually for runnable interface

[sahilanower]

Great explanation, crisp and to the point, the deadlock example was really heart-touching one 🙂

[SURA]

Thanks Aman for such a insightful vide on multithreading covering almost all the topics. Keep uploading more videos

[abhishekgaur]

this video is a hidden gem. Many thanks😊

[sudheerkumar-tpmg]

Super Concepts Taken, also please cover on Completable Future as well

[kshitiz]

very good video on multithreading. please keep uploading more videos.

[void]

Why you are not uploading a full java course please upload a full java course eager to learn from you

[ravitejam]

Please make same video on Collection framework as soon as possible 🤩

[chetan]

nice video, you missed locks and concurrent collections? can we expect a video on this as well please?

[manish.adhikari]

Great informational video. I was wondering how can we ensure a block of code is executed by a single thread in a multi instance scenario?
I have a use case wherein i have to create a file and insert an audit entry in db. I want to create the file once hence obviously i don't want any other thread from the same instance or any other instance to execute this code block. This can be implemented well in a single instance with locks or as explained with single thread pool executor but how can we achieve this in multi instance? Appreciate your guidance in this.

do you have any copoon code for java kit

[evelyn]

Will the function be dubbed into Portuguese?

[PRANAVPRAKASH-ys]

Brother, first of all thanks...Please stick to Hindi brother, comprehension of concept in our mother tongue is quite high. That the reason I watch your videos. But nevertheless, kudos for your efforts.
