Well done bro!!! Eagerly waiting for the Microservices tutorial you are planning

How does it achieve a locking mechanism on Nodes ?

manishsoni

Before Java 8, HashMap was dependent on LinkedList to maintain nodes but since Java 8 it is Red Black Tree which has improved the performance according to Big O.
But thanks for the video

rajatraok

Thank you bhai, aaj sahi se samjh aaya, ab explain kar lunga❤

You didn't say that concurrent hashmap allows reads even if it is locked by threads performing updates
That's an important aspect during interview

mustafaz

your work is great springboot video is too good thank you so much

sekhar

Thanks for the such an explanation. I had a doubt, will the read works on the same node where the update is happen ? if so, which value it will show old value or updated value ?

steffianusha

what is read and write operations performed on same node, will it allowed or one thread will lock that segment till other operation is done?

Hey, Could you please make a video on LinkedBlockingQueue and ConcurrentLinkedQueue?

siddharthsharma

You never discussed about synchronized map

Nice explanation. Was really helpful to revise. Kindly make more videos on java interview questions on such critical topic and kindly try to keep the length of the video as short as this if possible

Could you make a video on Splititerator in java ?

ShinAkuma

3:30 its 'bin' not 'bean'. Dont get confused.

Initial capacity of Hashmap is 16
Please correct in your video
anyhow you stored element from 0 to 15 that makes length as 16

How much should we learn about thread for modern day Programming?

senseigaming

Thanks Shabbir. Informative as always. I knew some of it. Can you provide any possible links where I can learn this more in depth. As you explained in the video this all is in high level there is more complex things happening. So can you possibly provide where I can read about that.

Multi threading dedicated video needed please

nisabmohd

@ daily code buffer please do indepth tutorial of multithreading not just basics how exe.. xyz work behind, i believe very few only explain that not make much sense, you got skills, please help us with that one playlist
