Sir you made me understand collections concept in very little time. Thanks a lot. I am now comfortable enough to use collections in the DSA questions and other harder topics in Java. Waiting for more videos in Java series. thanks once again.

[riteriddhi]

Put in a lot of effort for this. I hope this would be helpful. Very few resources would cover topics in such depth. Also, next video on Multithreading. Just need your support to continue making this, as making tutorials are the hardest thing to do🙂

[tanaysingh]

Pure gold, putting in extra effort to cover all practical aspects of collections much appreciated

[mistiquevin]

Fantastic course! So glad to have found your channel. Looking forward to checking out more videos from you. Your comprehensive coverage of these concepts is very valuable!!!

[harshinredzone]

My respect for you has increased multifold after watching Collections, MultiThreading, Lambda videos. Thank you so much, Riddhi. A lot of efforts goes into making these videos. Making them for free is next level thing.
Would love if you can cover stream separately.

[kalpshah]

I have never seen such outstanding and premium content on the collection framework ever. thanks bro now i say that i master collection and credit goes to you...!!

[MadhanKumar-mtjc]

Everything under a single hood really concise and clear content for perfect beginner

[MaharashtraNaukari]

watching the first video on your channel and watched and understood the 3 Hrs video in a single go, on the internet no one has explained Java collection in this easy manner while including all the smaller points, Thanks for the video 🙂.

[quotcode]

Best explanation ever. Thanks a lot Riddhi for sharing it. It cleared a lot of doubts of mine and I m now very much confident to implement any collection.

[sankarapuvishnuvardhan]

This is the best video I found on collections and thanks for putting lot of efforts, to make us understand the collections in deeper way.
Please make a video on core java in interview aspect

[nitinsingh]

Need to switch job, but need to understand spring boot perfectly. Pls make on that also...a perfect playlist.

[AdityaRaj-tiuz]

What a masterpiece it is Hats off to you sir, this is my some how 11-12 video on collection framework but the level of depth you gave me is much much much satisfactory.Please make more videos on what ever topic you want on java because i actually enjoyed this alot

[yogiswaru]

Thanks for the in depth explanation of collections. Super insightful.

[AalasKaPedh]

Amazing video..super resourceful and we'll communicated!! Thank you Riddhi

[rahuljmd]

Thanks for the video, maybe we will be needing from scratch implementations of these Collection classes...

[AkashVerma-sqeq]

In iterator example, why do we need to have OurGenericList<T> inside the inner class since we can use the outer class's variable items?
Instead of index < list.size cant we use index < items.length ?

[ak_arun_karthik]

Very helpful I recently joined Zoho and I was a mean stack dev. You made Java Collections very easy for me

[Mr_Tesla_]

Awesome video as always. Just wanted to make a request please make a course on entire java development if possible along with core and java too. There aren’t any complete good courses available online as of now. I wouldn’t mind at all paying money to learn from you. Pls consider this request

[adegokeakanbi]

Thanks a lot for this detailed video. I have learnt a lot and I appreciate the great effort put into this video to teach a lot of people. More success. Thanks a lot!

[ChadSigma]

Great content bro. Finally someone is teaching industry oriented stuff.
