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.

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.

[casbox]

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

[riteriddhi]

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

[HardikPatelhardsome]

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

[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.

[wilhelmmeyer]

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.

[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

[ytagarwal]

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

[vellacreator]

No words can describe how grateful we are, thank you for putting out such valuable content which is offered by many Institute at hefty price of 50k+

[ayushrai]

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

[soumavabanerjee]

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

[vellacreator]

Please please please keep posting such in depth vedios, if you are busy just post one in a month, will be extremely thankful❤❤❤

[harshdhuppar]

Sir, it's the best video I found on YouTube covering this concept in great details. I used to fear of this topic whenever I see it or need to use it in my project.

I would request to make more such videos please covering this depth. If you want we can recommend you some topics too of whose quality videos are yet not available you can make on them.

Your videos help a lot of freshers like me who are just placed / going to be placed in this industry.

Hope you will read this & cosider my & everyone's request.

I can only say the impact of this video & such type of videos is immense in life of someone.

[TheBikerDude]

Excellent video on Java Multithreading concepts with examples. Kudos. & Thanks.

[sridharshree]

How you are speaking that much faster.. and explaining without confusing, You have sound knowledge on those concepts definitely. Thanks for tutorial.. I am learning this concept from you.. Multithreading and speaking skills🤣

[AlgoCraftsmanAniket]

Till the time it is the best tutorial for the multithreading i saw on YT for free.. Great work..!

[sejalseth]

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

[sreddy]

Bro, subscribed. Just 15 min into your video for the first time and subscribed on spot. What a concrete explanation ❤

[ashoke]

For this single video alone, you deserve a million subscribers!
