World's best explanation 👌💯 highlight is you have explained with the debugger mode no one will explain like this. While I'm writing the codes and debugging expanded the hashtable there is an lot of nulls available but now I got to know thes reason. Thanks for your explanation 👍

Flawless explanation. Thanks for this video, I liked the way how you have shown with debugger mode on. I am lucky that youtube has suggested me this video.

Hello Sir, a very nice video on the explanation of hashmap internally . Just wanted to correct a point that when a bucket with collision occurs during get then "equals" method is used to find an exact match while iterating through each element in the list. The video mentioned "hashcode" instead. I brought this pont only because many students will grasp the concept from this video and these key concepts play a vital role as a developer. Thank you

Nice video sir and your explanation is awesome I haven't seen this type of explanation 😀

Brilliant, Wish every technical topic in any stream have these kind of videos to explain in details...
Looking forward to more videos like these.

The main thing to explain here was how hashset avoids null keys and how it is synchronized. Other than that it was good

Hi Naveen, Can 2 keys have the same Hashcode? When they have the same index collision occurs. What happens when they have the same Hashcode. also @18:58 when you said peter and Naveen have same Hashcode did u mean they have same index?

[krishanuchakraborty]

I don't understand why these beautiful videos of yours are not gaining traction as much as your Whiteboard or Selenium series...

[velanc]

Nice one Naveen.Thanks for this video. Waiting for more :).
