bhaiya, please video Hindi me bhi banayiye,I need your video in hindi

[@shubharawat9023]

Your OOP series helped me a lot in my Adobe interview. I answered the Qs in the same way you have explained in the video. Abstraction vs encapsulation, compile time polymorphism vs run time polymorphism, and so many more that you cleared in this video. And I got the intern offer from Adobe. So thank you very much. I owe this to you. Keep up the good work.

bro i understood this line "you can inherit but you can't override . but i didn't get this line "you can run but you can't hide ??? what's meaning of hide here ?? can you explain me ??

[@ChessKing-ud6sg]

​​@@himanshuchoudhary2514 " You can inherit but you cannot override" in this context means that no matter what you do( even creating another static method with the same name in the child class), you can't override/outrun me , so as both the statements covey a little bit same meaning he uses, you can run but you can't hide it , essentially saying that whatever happens the end result will remain same

[@pratikagar2009]

Reached this video following all the above videos in the playlist, I am dragged to comment because of how amazing is the quality of these videos. Hey everyone, I'm a six years experienced software engineer and have a good command of programming languages like Java and JavaScript, but I should most certainly say this every single video in this playlist has unique things to be learned. Kunal makes concepts, big jargon in programming language and of course interview-level leetcode questions very simple. @Kunal, appreciate the efforts you put into this entire playlist, and the idea of free education to all is commendable. No other course can be this structured where Java, DSA are covered in such detail. On behalf of everyone here, would be great if you find time to complete this playlist adding leftover topics like Dynamic Programming etc and making our lives simpler. Counting on this playlist for DSA preparation as a whole for my next switch. Please note: commenting as a part of this video, but this is valid for all the videos in this playlist. Don't trust me, watch any Interview Question videos. Thank you so much, very helpful and recommended for everyone. 🙂

The explanation of method overriding was phenomenal and the answer to the question why static methods cannot be overridden? This is because overriding is related to objects . Methods and variables when declared static have no relation with objects. So method overriding is not possible in static methods. Kudos to you and congratulations to us for receiving a great content.

this time also worth watching the whole video. Also the videos are so interesting feels like story telling and boom you've understood the whole concept

[@MrVrtex]

51:00 "Try it yourself, Experiment orelse you will never understand how it works" Perfectly said. I learned everything by Experiment. I learned about hashmaps, arraylists, linked list all by Experiment. I never watched your videos before. But off course after I watched your videos it got more clearer. I never learned about linked list. But in my first question in leetcode of linked list, I tried it myself and eventually got the idea of how it works. Now I have almost solved 30 to 40 linked list questions in leetcode (mostly medium). Still I haven't watched any linked list lectures. (Eventually I will 😅)

Hey , kunal first of all thanks for such an amazing course ...but @ 1:21:11 you said that we can do method overloading by changing the return type also...but when I was trying out it on my laptop it was showing error then I checked it on the Google and found out that we in java , method overloading is not possible by changing the return type of method only ,so I just wanted to correct this point .
