[@amitrajitdas31]

Not a JAVA Dev but the topic of multithreading always made curious, never found so detailed explanation anywhere on YT. The way you explained thread class, object locks & sync was next level.

[@rite2riddhi]

Thank you

[@rite2riddhi]

Few advanced things like Executor Framework , Thread Pool , Atomic Integers would cover in a separate video later.(depends on this video's engagement)

[@udhayasankar113]

Pls cover these topics as well...also streams

[@imdragonm]

Please do , must do

[@techdemy4050]

@Riddhi Dutta Pls cover advance topic also I really loved this content.

[@chinmaypingle4770]

Pls make the next video for advanced concepts

[@sayankarmakar13]

please make videos on these

[@aaronbruckner]

Very solid work dude. Thanks for taking the time to go over all this. As a 10 year node dev at a big tech company, this was a great java primer. Covering executors would be awesome.

[@HardikPatelhardsome]

Awesome, concept cleared here! After 7 years of reading multithreading here and there. Big Thanks Bro!

[@casbox2667]

Basically the content of three lectures explained in one. Thanks mate!

[@wilhelmmeyer89]

This is good. 2 hours with most helpful information. You talk fast. If you wouldn't have talked fast, then I would have increased the speed.
This is systematic. The examples are not too simple and you you cover the topic nay you go deeper into it by expalining JVM mechanisms. You know your stuff.
This is really helpful for many Java developers. I haven't found such well done videos about threads on Oracle pages or anywhere else. Thank you.

[@shreyashchavan6120]

Thank for starting the series on Java. Looking forward to many more videos from you ☺️

[@manjiripathak5974]

A surprized video on Multithreading, never thought as learner I will understand so much in details with program. Thanks for deadlock details situation and how to resolve it .

[@victorpal6915]

no one has elaborated Multithreading in this way. This is really awesome.

[@mounicareddy728]

Amazing content. Best Multithreading video I have watched so far. Great work.

[@niftytrading7038]

Excellent Course! Very well structured. Thanks a lot!

[@shahidsarwar256]

ABSOLUTELY BEAST MODE EXPLANATION! SOLID!

[@aishwaryapani4662]

I've never seen such easy explanations of these concepts❤. Thanks a bunch! :)🙏

[@soumavabanerjee5925]

Completed the entire video last night. Will watch it a few more times to clear up some of the concepts. Crystal clear explanations!

[@rite2riddhi]

🥺🙏

[@user-rj2pd3ig7d]

super sir. Literally the multithreading topic was very interesting & have learned lot from this for interview. Thank you!

[@priyamgupta569]

bhaiya maza aaagya hai ksam se, thread using class and using runnable interface got me hooked to you honestly.
Great job!

[@nawid31]

Hello Riddhi,
Greetings form Germany. I have an exam at my university in a few days and this was the most helpful video I could find about this topic. Great work, keep it up! I would really like to see these kind of videos for the topics Generics/Wildcards and Sockets/Streams aswell.

[@dev.hpatel]

Deep Diving into Thread Class chapter is Awesome. You explained in a easy words.

[@kishansanandia2208]

Amazing work buddy. You made really complex topic a piece of cake. Thank you so much buddy. Keep up the good work.

[@ChetanChauhanVlogs]

Finally found most of the thing in one video. Thanks for sharing in detailed way.

[@utkarshyadav6993]

This is the real teaching which impacted my understanding and that is what I was searching for. I have a huge expectation from this channel please do post explanation of similar important topics.

[@jayjoshi1366]

Really appreciated and grateful to get such a content on Multi threading. Please get some more content on Executor framework, Thread schedulers, Thread pooling, various locking mechanisms, etc.
Also it would be good if you show some differences between sleep and wait method, start and run method which will imprint all the concepts well in the mind.
Thanks a lot again !!

[@StellasAdi18]

Love the energy, passion and way you explain. Pure gem!

[@rite2riddhi]

Thanks aditya.

[@sejalseth9475]

You have explained a complex topic in such a simpler way. Thanks !!

[@ankur20010]

Best lecture on this topic that I have seen for a while.

[@ameyakasar2148]

This is one of the best videos I have seen about multi-threading, thank you for making such an awesome video. You have great passion in explaining such complex topics and it's a great learning experience to watch your video!

[@rite2riddhi]

Made my day. Thanks

[@just_patricia280]

The way you just explained every detail behind, dude, you are made for this !!! 10/10 fr.

[@ashoke8031]

I'm really impressed how you explain abstract topic like multithreading in such an easy way. Keep up the good work 👌

[@rite2riddhi]

Thanks man.

[@abhishekjha9905]

I have learned java tutorials earlier from various sources but the way riddhi bhaiya explained is magnificent🔥 top notch content and i've learned multithreading earlier but i'm unknown about lot of internal workings of java concepts.Thanks Bhaiya for making these quality contents yield() such contents regularly😅 .

[@mrityunjoybarman9098]

Best ever video on multithreading I'd say.

[@harshinredzone]

[@vamsimudaliar7931]

Such an in-depth Explaination. Thank you !!🙂

[@bhishamudasi1698]

Awesome lecture indeed. Very well explained. The only missing part in multithreading which I could think of is JAVA Lock API, which is sometimes asked in interviews as well.

[@saikumargoud3257]

thanks a lot @Riddhi now i cleared all doubts of multithreading hoping more and more video lectures in future

[@mayankbadika3101]

Great explanation and thanks for showing this concept with code implementation

[@ayushrai6699]

Need a advanced multithreading video too. This was too good🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥

As a newbie to this topic I can't tell how well the video is, but indeed it will be really helpful in understanding it deeply since the knowledge and effort you put is 5/5. Thanks

[@shiva4shivendra]

Thanks for explaining this complex concept in such an easy way

[@nileshtiwari7499]

Thanks, brother !! 😚

[@VIVEKKUMAR-pw1zl]

Very informative, Thank you

[@EZ_Coding_]

Your videos are always a lot helpful

[@TheSakthibalan]

Great :) I learned many basic things related to threading clearly,
1) mainly object locking- how it works - common object lock across functions will block all those functions for other threads
2) static method lock
3) use of lambda to create runnable Impl ()-> {}
4) why to use While loop in threading instead of if - when used with wait, notify
5) Internal Impl high level details of Thread and Runnable class
6) Deadlock simple example program
7) synchronized method vs block- difference and how lock works in them
8) and some more like functions wait, notify, notifyAll, join, sleep, thread states
Please consider to make advanced threading concepts Part 2 video, Part 3 video
You can also share the code you used for Demo purpose during this video

[@debanwitadutta2303]
