[@harithasri8372]

If anybody wants to start this video but feeling this is lengthy, dont think twice just watch it. His videos are worth watching even thought they are 2 hrs just watch. We will get to know every piece of info about that concept

[@shankumondal2881]

Didn't know the concept of Virtual capacity so far.!! Thanks for sharing . 👍

[@sangeetasuman7244]

It's good way of teching sir because all mentor of youtuber tell about basic concepts but ur way of teching basic to advanced really nice 👍 I always look for this type of teacher

[@jeyhunaliyev1765]

Watched it till end Loved the way of declaring array-list with Arrays.aslist method Its very clear And especially Printing with lambda its awesome Thank you very much Naveen

[@naveenautomationlabs]

Glad you liked it

[@sangeetsingh8980]

Ur Teaching is just Amazinggggggggggg Naveen. Loads of blessings to you sir.

[@naveenautomationlabs]

Most welcome ☺️

[@muralikrishnapentakota3875]

First time i came to know about virtual capacity, Thank you so much Naveen for neat explanation

[@naveenautomationlabs]

You're most welcome

[@sureshgarine]

I like the iterate over an array using iterator and lambda expressions as well. Thank you

[@nidhipriya2068]

I can only say "Naveen is best"...Thank you:)

[@jayantamandal9732]

Thanks a lot Naveen for the detailed explanation including the stream and Iterator usage. In future if your time permits can you please make video on API automation using python

[@rishabhgupta9033]

Excellent videos sir. A small request, please provide the Screenshots or notes of the lectures🙏🙏

[@DipakDas-tm3nu]

Naveen your training video is amazing, I have learned so many thing in java from your old video, this is the new one. One thing I want to ask you when I revision this java collection is which process I follow, can I see the video again and writing the same prog or is any trick to revision.

[@meghraj]

Greatest achievement for this video is that almost 7.5k view but no dislike yet .... amazing @navin

Hello Naveen. I am following your video as as you have shown at 16:44, you are able to see the virtual capacity. However, in my case when I run in debug mode, I am not able to find it. I can only see the element that I have added to the ArrayList. I am not able to see the remaining none elements (which is the remaining virtual capacity) Please could you help me to understand how can I see the virtual capacity. I am using Eclipse IDE on Windows 10 OS.

[@vibhooti2666]

Same here

[@gauri_korde]

same here , I'm using JDK 11 on Intellij

[@aarunkumar]

Hi sir your collections classes are very good. Sir I have one doubt, do we use collections concepts in selenium automation or for interview point of view we need to know collections concepts

[@ramachavali4015]

I have few doubts, how to contact you. Need your help in understanding few concepts with respect to my project plz 🙏🙏🙏

[@nagashriravindra7746]

Thank you so much :) too good :)

[@naveenautomationlabs]

Thank u

[@riyagupta1447]

very well explained

[@shivaprasad8804]

Nice video. Default Initial Capacity or Virtual Capacity of an empty array list = 10. Once the ArrayList reaches its maximum capacity, then a new ArrayList object is created with: New Capacity = (Current Capacity * 1.5) + 1

[@mohammadfarhan2290]

Means (10 * 1.5) + 1 = 16

[@shivaprasad8804]

@@mohammadfarhan2290 Correct

[@gauri_korde]

Hi Naveen, When I'm running the same program in IntelliJ , I can see only 1 memory slot is allotted for each addition not the chunk of 10 as you showed in video. Say I add 1st value - one slot is allotted then I add 2nd value then second slot is allotted. I'm using JDK 11.

[@jinalshah7023]

Hello Sir,I have one question,Why should we change the virtual capacity? what is the exact function of it?

[@divakarpandey9094]

Thanku so much sir

[@sainathvallampatla5135]

Does array list automatically increment the virtual size by 10 if we completely fill the 10 elements

[@ravinderyadav9581]

Hi Naveen sir, In the debig mode i am not able to see the virtual capacity picture, instead i am getting an error message.

[@vijayapriyapalanikumar6213]

Does virtual capacity dynamically updated while we add arraylist morthen 10 data. Arraylist ar=new Arraylist();

[@mayank.007]

what is the use of virtual capacity ? Is there any advantage of having virtual capacity?

[@monikaveeramalla3381]

Please do a video on multithreading

[@nibeditajinu]

Thank you!

[@PratikTate]

Hi Naveen, please suggest me some books to improve communication..

[@vikasyadav-es8uh]

StudentList.forEach(System.out::println): I always print like this

[@naveenautomationlabs]

Ya this is called method expression.

[@sandeepbilihalli2643]

After adding 10 elements to arraylist what will be the virtual capacity of arraylist? How much virtual capacity gets added after the existing capacity is filled ?

[@arvindsharma801]

Incremental capacity = Current capacity *3/2 +1

[@nalinireddy2038]

hi sir can you explain difference between iterator and list iterator

[@goldfan5523]

Sir, please something more on AWS🙏🙏

[@naveenautomationlabs]

Ya more videos will be there on AWS lambda and api development using Lambda and api gateway.

I could not find the virtual capacity even after debugging , i did mouseover but it is only showing the physical capacity :(

[@desuteja502]

​@Pushpendra Hanumanta tq brother :) same issue for me also, after changing to java, able to see v.capacity.

Sir your some updloaded video are bit blurred so please improve clarity

Naveen could you please share the code. GitHub Link

Hi Naveen, ArrayList is not identified in my eclipse. even after adding( import java.util.ArrayList ) manually it gives an error.Am i missing something. Please suggest
