I think you said wrong about join, Join is to ensure that spawned thread join the main thread before proceeding further. If there are 100 thread and you make join call then still those 100 thread run in parallel but join ensure that they get completed before your main process.....

[@baibhavghimire3827]

Correct

[@shreyanshjain2347]

Thank you so much for this excellent video. very informative and helpful. thanks again.

[@SivaReddyJavaTechie]

thanks Shreyansh jain :)

[@deepak123417]

You Should provide examples u explained time slicing and Thread pool, example will give us more clarity and also use eclipse to try multiple options.... its just a suggesion

[@SivaReddyJavaTechie]

Agree with you. Basically this video helpful for the candidates who are preparing for the interviews and they already should have the background on multi threading. I uploaded serious of videos on multi-threading in detail with examples: Here is the URL: th-cam.com/video/GfY5i4zCyro/w-d-xo.html

[@tubepankajyou]

Nicely explained

[@deepak123417]

[@sirigiris5062]

[@SivaReddyJavaTechie]

Thanks Sirigiri.Yes, I agree with you.

[@pathanrauf]

Hi Siva, can you please share the prepared stuff which you are showing into the video.

[@aykarageorge]

Isn't the join() in Thread used to hold off other thread executions until the currently executing thread is finished? it was written that 'join() is used for the currently running thread to die'.

[@80sudha]

Yes, u r correct.

[@ManishKumar-sv5my]

wait() and notify() methods are not methods of Thread class. These methods are present in the Object class.

[@shreyanshjain2347]

Hi Siva, you mentioned thread scheduler is responsible for scheduling the threads and then it's request to CPU. so my question is, CPU is only responsible for the making thread run? or it's only the thread scheduler. Please Clarify.

[@SivaReddyJavaTechie]

Shreyansh - Yes you are correct. Thread scheduler responsibility is to delegate thread to CPU, now CPU execute the thread based on its availability.

[@pratyushkashyap7544]

FYI... wait(), notify() and notifyAll() methods belongs to Object class not the Thread class

[@SivaReddyJavaTechie]

Yes Pratyush. I agree with you.

[@RaghuKumar-ew7tf]

thank u bro

[@RaghuKumar-ew7tf]

please make video on struts 1.3 interview questions

[@SivaReddyJavaTechie]

Raghu - I will upload video on struts 1.3 interview questions. Please stay Tuned.

[@saeedalam2510]

[@SivaReddyJavaTechie]

Demon thread is a helper thread for the user threads. Example - Garbage collector is a demon thread.

[@nirmitsrivastava]

[@AbhishekSharma-yq3jn]

please be more clear on your answer

[@mehtabmehdi5046]

[@SivaReddyJavaTechie]

Hi Mehtab, If I don't explain fast, it may take at least 2 hours+ to cover all the Q&A :). No reading from the book and explanation comes from my experience. :)

[@samirvb]

Very very Poor ! No proper thought process or clear explanation.

[@berkk1993]

[@mehtabmehdi5046]
