[@N7000nn]

I started watching your videos several months ago and today I signed up for my first junior job for java spring developer. Thank you so much, you changed my life.

[@DailyCodeBuffer]

Great 👍 Congratulations 🎉 Glad to be small part of your journey ❤️

[@rinkarto]

Great to hear these success stories 🎉

[@azam11250]

Congratulation Bhai, By watching ur videos only i started by Microservice journey 3 yeears back.

[@GodofStories]

Great explanation using the Java implementation to show the internals.

[@anrgkdm]

Nice explanation. Please make a video on working of HashSet and TreeSet. They ask this in interviews for experienced developers.

[@nalcow]

sir you are awesome, what a great source of information your channel is, thank you

[@KritiJar-e6n]

Great explanation. Recently started watching your videos. Really enjoying it. Thank you!

Thanks.... 🙏🙏 Bhai, please make videos on Spring Framework interview questions... Btw, what happened to your right eye? Looks red

[@DailyCodeBuffer]

Infection, better now Thanks for asking

Great job buddy, congratulations for 50k subscribers. Thank you.

[@tysonthedesiretriever8393]

as always very clean n sufficient enough videos .... doubts 1. why dont we use balanced tree in the first place instead of linkedList 2. what is the criteria by which tree is made ...i mean go to left or right 3.. how does hashMap.getKey() works

[@ramasamyramasamy2423]

Purpose of using balance tree later than linkedlist is about the size of the nodes added at specific index of the object created for the hashmap. Dismantling a sub tree of elements that added into balanced tree while deletion of elements in hashmap made, will be faster than removing an element from the linkedlist attached to the index of the object when deletion of elements size is larger. Dirtying the hashmap's elements will be slower when linkedlist size is increased...

[@brijeshkumar3900]

Hats off bro !!! the way you explained !!!

[@DailyCodeBuffer]

Glad to hear that 🙏🏻🙏🏻

[@rashmimuchlambkar8490]

Hi great explanation!! please let me know why/when should we override equals and hash code method in Java ? If you have already made a video please give me the link..

[@paulraj2807]

Excellent explanation 👍👍

[@DailyCodeBuffer]

Thanks 🙏🏻

[@beksaylor]

@Daily Code Buffer Great video, what IDE and Color Theme are you using?

[@DailyCodeBuffer]

Intellij Idea Xcode dark theme

[@saurabhchalikwar6822]

Bring a tutorial for rest services because you have posted videose even on microservices but missing about rest service and mvc. Please make a video on it..

[@techtips7641]

Excellant explanation it really helps

[@sharadpratap]

[@faixan13]

excellent explanation. I didn't know about the java 8 hashmap optimization . learnt something new today. :)

[@dhilip77]

I like most of spring boot videos. Do you have any plans for language scala with, spring boot. It helps for data engineer profile like me to build top to end.

[@rushabhshah392]

Congratulations 👏 for 50K .. keep up the good work 👍

[@DailyCodeBuffer]

Thanks buddy 🙏🏻❤️

[@gowris442]

Bro here i have doubt in one place while doing get operation you are particular key hashing will happen and return index of the position of key. If its not match that key it will look oneby one node traverse if its not found it will return null value finally. Why we need to check one by one node to traverse and find out that key. If you do find exact key value means why could we can use balance tree logic to find out or some search mechanism to find out immediately not by way of traversing node one by one.

[@afrozkhan.]

Thank you very much Shabbir nice explanation very much helpful please make many more videos on different topics... Congratulations for 50 k subscribers.

Hey Man, As always u will be awesome, finally, I understood. Great Explanation

[@DailyCodeBuffer]

Thanks 🙏🏻

[@mohammedilyas8824]

Congrats shabbir bhai

[@DailyCodeBuffer]

Thanks 🙏🏻

[@harikrishnhaaraghuveeran5866]

Once the size of index increases from 16 , how will hashcode work for same key when it got inserted before and after index size increased?

[@svalyavasvalyava9867]

Thank you very much!!!

[@willofd1683]

Congrats bro keep going

[@DailyCodeBuffer]

Thanks 🙏🏻

[@coder3842]

Crisp and clear

[@DailyCodeBuffer]

Thanks 🙏🏻

[@anupvishwakarma4214]

If the bucket size is more than 64 and one of the particular indexes reaches 8, then only the linked list will get converted to a Balanced tree. Please correct me if I am wrong.

[@anand8019]

Clearly explained 👍

[@DailyCodeBuffer]

Thanks 🙏🏻

[@rishavgupta7868]

Aren't we getting the index from the key within range of 0 to size-1 after applying hashcode() method, if so, what is hashing doing then, what's the difference between both, please anyone explain...

[@tejachowdary309]

Can you please post a video on how to integrate our rest api with splunk and dynatrace

[@hrithikgoswami9808]

Great work man!!

[@DailyCodeBuffer]

Thanks 🙏🏻

[@kirankutte7073]

Hey Shabbir, Great explanation and i have doubt here, why we are using linkedlist in each bucket for storing the nodes,why cant we use simple arraylist?

[@umeshkrishna8921]

Array list is the array representation so it doesn't have nodes to connect, where as linked list has nodes which are chained to maintain the links between the nodes.

[@anushbabu5023]

Hi bro, please make videos on design patterns.
