alrighty

Something like that, yup

"all that stuff"

[@TheTimelessReverie]

Hey everyone

[@ankit_1012]

For me Understanding oops is now easier than understanding how to use discord 😅

[@KunalKushwaha]

haha nice

[@poorvagupta2399]

That's so true

[@ig_haxie]

20:30 if you cant understand: Generics provide type checks at compile time, and the produced bytecode only knows classes, methods and interfaces. Bytecode is executed at runtime and objects are created at runtime as well, Looking at bytecode, it doesn't contain the "type" of object we want to create, so it shows error.

[@aryanjoshi9703]

ya, may be the object creation statement (where the T is also present ) it will executed at run time and compiler will not be able to get the type of object.

I Never Like To Share Kunal's Video. I Hate Competition 😅

[@ramlanjekar2773]

this video was of very less energy and many things were taken in granted(i am saying this by watching every single video ) so people who are reading this may opt for any other videos for the given topic

[@ramlanjekar2773]

you just made this video very disappointing like i liked you throughout the series but last mai hugg diya

[@shubhamagarwal7876]

Kunal there is so much in this 1.5 hr video that is equivalent to 1 week of paid classes for 1.5 hr each day . So the one person that can encapsulate a 15 hr topic efficiently in 1.5 hr is one and only our Kunal.

[@sureeth1732]

So true 😎💯

[@gouravpanseja7236]

He literally rushed through so many things... didn't explain some.... didn't mentioned some.... and even left some for confusion..... have been following this sereis from the very beginning... but this one dissapointed me

[@Rahulyadav-lv7dh]

Some people hate this channel because they cannot digest the fact that CP is not necessary to be a good software Engineer well,A sun shouldn't stop shining because its light are hurting people eyes. keep shining Kunal we are with you

[@KunalKushwaha]

Ignore maaro sab bache hain

[@Rahulyadav-lv7dh]

Ok

[@sahilpatle6436]

41:18 In simple words. If 2 data are same the method must return zero(0). If 1st data is greater than 2nd data the method must return +1. If 1st data is smaller than 2nd data the method must return -1.

[@arijitmohapatra147]

Seriously there are many series on java but this particular series has some separate space in our ❤️

[@karanbadhwar4113]

How imp is Lambda function part ? As, I Couldn't understand lambda Function part.

[@minisri21]

This course is the best, there were things I used to consider advance level may be I could not be able to understand but with your bootcamp nothing seems impossible.

[@ridoychandradey8337]

Learned so many things at once. Rare video on youtube. Once again thank you very much Kunal.

[@meetsoni1938]

This video contains so many concepts but explained all it in the very easy way 👍👍🔥🔥

[@neharamesh7732]

Binged the OOPS playlist. 😁 Undoubtedly this was the best series. You keeping your word explaining every single line. Thanks for making our lives easier. Keep bringing such amazing series ! ♥

[@eminence_Shadow]

Liar

[@eminence_Shadow]

It would mean 11 hrs nonstop playing videos... doesn't make any sense..so liar

[@yashisharma4583]

Thanks a lot for this wonderful course😃

[@KunalKushwaha]

Most welcome!

[@anubhavgarg1728]

I just wanna ask while doing the deep copy through the clone method what we did was first of all we created a shallow copy of it then we updated the non - primitive array by creating a new object of array and then assign it to the arr variable then again using the for loop we reassigned each element of the array at its correct position. But can't we just call the constructor method from inside the clone function? or maybe we can't do it as the constructor method doesn't have a return type. I just asked this because as we know that in the constructor we are creating the array each time. So we are allocating memory each time using the new keyword. I have one more alternative inside of the clone function why don't we just create another human object and initialize it with the constructor that takes human object as parameter. That way we can simply assign the reference of that object to that object through which we have called the clone function.

Learnt a lot of new stuffs, oops series is Awesome. #LearnInPublic #DsawithKunal

[@adeditz3607]

One Of The Best PlayList in Java Oops , ❤️😘

[@adityagarhwal4]

Very much helpful course

[@supratimbhattacharjee5324]

Checked exception is not handled by compiler, all type of exceptions are handled in runtime, checked exception is just giving warning that this kind of exception may happen while runtime so the code will not compile and will give compilation error, so we need to write our exception handling code beforehand so that this kind of exception will not happen in runtime

[@kiranrajb2960]

Bro can I ask who is Rahul Because u always use rahul object

[@amthephoenix007]

Amazing lecture Kunal!! Had fun :)

You are simply awesome!

i don't understand the "Lamda" part and throws keyword use in actual work and that's I find problem in object cloning. i'll try to read orcle doc and gfg let's see

[@nirvattaenterprises3047]

Great Work!

best course on youtube😍

[@kanchangupta6007]

i loved watching your teaching, it is way too easy to understand. one of my friend is looking for python tutorial. i checked on the website but it is saying coming soon. when will it be available

@Kunal Kushwaha, You are doing great job. Can you please recommend me youtuber who teach Frontend regarding things.

[@aradhyapatro3796]

Was yet another amazing lecture I specifically liked the exception handling part cause I frankly was struggling with it bit recently.

kunal when are going to upload trees and graph videos. And thank you so much for teaching.

[@BROOKnim]

@ 1:09:30 we dont need to do "throws Exception" after psmv?

[@vigyanta94]

Thanks Kunal

[@AbhishekRana-fx7le]

Correction: In shallow copy as kunal said for non-primitive ones, reference variable points to original one only rather then making a new one but this not goes for string because since strings are immutable (we cannot change it)and hence it will create new string for the clone one

[@inspiredbyinfinity]

bro kunal is right! no new string will be created

[@subhamsahu4082]

love his tutorial

[@BackEndGenius]

amazing stuff.

[@user-mt2wn6hf8x]

43:57 if its calling Arrays.tostring (list [of type student array]) means Arrays tostring method then why it needs its own class to string method

[@chris-p-bacon1053]

Vhaiya please make a roadmap for CS students semester/year wise. That would be a game changer coz most of this types of videos are made for keeping CP at the centre.

[@KunalKushwaha]

I will
