Apologies for the uneven audio at the beginning... I am trying out a new microphone. Hopefully will be better by next video

The best tutorial to explain reentrant lock and pairness. Thank you, great job!

[sureshchaudhari]

nobody comes close to explain multithreading like you .very nice sir.where do you work

[sauravsrivastava]

Awesome explanation. Truly love the way you explain and clear the doubts.
Would it be possible for you if you can also make videos of explaining the collections internal structures like how does it work?
Thanks

Your explanation is too good bro i have just small suggestions that please provide a link for you website where from we can read easily this all

[ganeshradiga]

Thanks for an amazing video, However I have a question, apart from the recursion you mentioned, are there any practical scenarios where this acquiring the same lock again makes sense

[rahulseetharaman]

Excellent explanation. Clear and well articulated.

[parthec]

Thank you for creating such wonderful video, kudos

[custardapple]

Loved the explanation on covered concepts.. very clear ... But some things are not covered e.g what happens when multiple locks are taken and what is the use case here..

[suhani]

Very clear and simple explanation of the concept...

[rajeshg]

Really awesome explanation .. I was read oracle docs on reentrant locks, it has just two lines of documentation.. I've couple of questions here 1. Can we use synchronized block instead of the reentrant lock If there is a recursive function call ? 2. On the trylock() method, how does setting timeout to 0 would achieve the fairness? Please elaborate

I finally understand what ReentrantLock is
