Done thanks Thread pool instead of creating a 1000 threads which is expensive, can make a fixed size pool and submit 1000 tasks to it. 3:40 how it works internally 5:30 ideal pool size for cpu task is number of cores 9:30 thread pool size for io intensive tasks
A very intelligent statement. If your tasks are I/O intensive e.g. DB calls, Network calls. Most of the threads would be in waiting state (waiting for DB response or Network call response) in such a scenario having a large thread pool is the right way to go. That way you would be able to start more tasks. Thanks
Guys please share his videos in other groups. we have to support this kind of content and it will be very useful to people who are looking for good content
Really great explanation, adding one formula for I/O intensive task, according to "Java Concurrency in Practice" Number of threads = Number of Available Cores * (1 + Wait time / Service time)
There are so many videos for multithreading available in UA-cam but I found you best because of your diagram presentation which is unique. You explained very well. You are awesome and continue with this key feature.
Holy Moli buddy!!! This was spot on! The BEST on the internet, cleared all my doubts right from basics to advance.. Super Thanks, I really appreciate great people like you that helps the community.
I as individual surf youtube a lot for learning purpose and almost have watched most of the youtuber on internet, But this channel is at another level in terms of quality . Thanks a lot sir . It would be great if you could take out some time and nail the microservice buzz words
You know while I start the interview preparation I'm watching all these videos saved , and this is my 3rd time watching it while I'm moving out of my 2nd company....🎉🎉 Thanks for your great work .

Hi Deepak, I just watched all your 4 videos related to ExecutorService, you have shown how things can be explained in a super simple way yet powerful. Great job!! thanks.
Thanks for explaining in both code and internal visualization of threads. Great explanation. You have explained complicated topic in very simple way.. Thanks a lot
Could you please teach the rest of India how to speak English. You are the poster child of clear flunet English. Your pitch and clarity in the words are masterful. Also your knowledge is strong, I love the tutorial and I am as American as corn.
Thanks for this clear explanation. You are doing a great job. I just wonder what is the strategy you follow to learn the concepts in crystal clear? Could you also share the resources (book, articles, docs) you follow when you were learning this topics?
Guys.... the absolutely most crystal clear explanation of Thread Pools I have ever heard. Beautifully sparse, no-noise or arm waving... well-presented and recorded. Bravo... I have become a great fan and are convincing others as well !! One small request... what is the cursor enhancing software you are using in the presentation ???
Your way of explaining the topics are really good. I am having one question. It might be stupid one,but I wants to know How to handle the Atomicity for write and Read operation in Such case. Pool size is of 20. t1 to t20 are doing write operation. ---> They will be in waiting state t21 to t30 are doing Read operation. ---> In between any of this thread comes in and start reading and get response before completion of write operation of all 20 threads . It may get old data.
Introduction: - The video discusses the concept of thread pools and the Java `ExecutorService`. - It explains how to efficiently manage tasks using a fixed number of threads. Key Points: - In Java, running tasks asynchronously is straightforward using threads. - Tasks can be executed synchronously by creating a class that implements `Runnable` and overriding the `run` method. - A new thread can be created with an instance of this class and started. - To run multiple tasks, one could use a loop to create and start new threads for each task. - However, creating too many threads can be inefficient as each thread corresponds to an operating system thread. - To address this, a thread pool can be used to manage a fixed number of threads. - Tasks can then be submitted to the thread pool, and the threads in the pool pick up and execute these tasks. - Using a thread pool reduces the overhead of creating and managing threads, improving performance. - The ideal pool size depends on factors like CPU-intensive or IO-intensive tasks. - For CPU-intensive tasks, the ideal pool size is the number of CPU cores. - For IO-intensive tasks, a larger pool size may be beneficial to handle waiting states effectively. Conclusion: - Choosing the right pool size for thread pools is crucial for optimal performance. - Understanding the nature of tasks helps determine the appropriate pool size. - Java provides the `ExecutorService` interface for managing thread pools, offering flexibility and efficiency in task execution.
Loved the explanation. Just a lame question. For a CPU intense operation, shouldn't the ideal thread pool size be (no of cores-1) as there is already a main thread running?
I must tell you , your explanation on all topics are very clear and easily understandable. Thank you somuch for the vdos .. :) .. Can you please upload a vdo on React Js , If posible.
Thanks a ton for sharing the video. Clear and concise explanation. May I ask you one question. Say If I have multi core processor and I have initialised ExecutorService with pool size as 100, all my task are IO intensive. Scheduler will make use of all core and will execute threads on different core. Is my understanding right.
Done thanks

Thank you, you have a skill for explaining complex concepts in a clear concise manner. I would love to see full fledged courses created by you.
This executor service series is one of the best ever educational UA-cam series ever. Thanks a ton. Your explanation is awesome.
Really explained well. This is the best I have found till now. Thank you. Keep up the good work :)
Thank you for the kind words!!
Yes this guy is awesome in subject and the way he is describing the concepts are speechless . I heard few concepts and all are above the notch.
best work ever, please make more videos !! I understand executorService finally
Guys please share his videos in other groups. we have to support this kind of content and it will be very useful to people who are looking for good content
Really great explanation, adding one formula for I/O intensive task, according to "Java Concurrency in Practice"

explaining with how , why , what , when -------------- everything about the topic -------- hats off ----------- u will complete 100k soon bro
There are so many videos for multithreading available in UA-cam but I found you best because of your diagram presentation which is unique.

ThreadPoolSize tread off with CPU core concept is excellent. You have cleared all doubts about the size of the pool.
Thank you.
You're welcome! I'm happy it helped
You know while I start the interview preparation I'm watching all these videos saved , and this is my 3rd time watching it while I'm moving out of my 2nd company....🎉🎉
Thanks for your great work .
That's so heartening to hear! Thank you for the kind words. Good luck for the new job. Wish you great success there as well.

Really precise to the point and very useful. You should do a podcast.
You should post more bro.
You really explain complicated topics in a really simple manner.
you explained this so clearly.....thanks for this !
Guys.... the absolutely most crystal clear explanation of Thread Pools I have ever heard. Beautifully sparse, no-noise or arm waving... well-presented and recorded. Bravo... I have become a great fan and are convincing others as well !!
One small request... what is the cursor enhancing software you are using in the presentation ???
It's pointer function in Google Slides.
Thank you so much for the kind words BTW! Means a lot to me
Just one suggestion, always give a link to working code, you explain well, the only thing I think missing is a link to a working code
Very well explained. Thanks for this. :)

Best explanation ever, thanks for it😇😇
Your way of explaining the topics are really good. I am having one question. It might be stupid one,but I wants to know
How to handle the Atomicity for write and Read operation in Such case.
Pool size is of 20.
t1 to t20 are doing write operation. ---> They will be in waiting state
t21 to t30 are doing Read operation. ---> In between any of this thread comes in and start reading and get response before completion of write operation of all 20 threads . It may get old data.
Loved the way you explained , it was neat and clear , thank you very much.
I watched many videos, but your video is the best till now I have watched.
Can you please make videos on "Fork Join" as well ?
Defog Tech! You live upto your name
Wow way better than the Udemy tutorial on Executors. You should expand on this and make a Udemy tutorial. Great teaching skills.
Thank you! My long term plan is to create my own site like egghead.io , let's see how that goes.
Very very well explained. Thanks.
maan.....where u been all these days? Glad to find ur channel. Please make more videos.
