Telusko, this video is brillant! NO ONE has been able to articulate this to me in such a clear way. I wish I had found this video YEARS ago. 🙏 Your channel is pure🔥!

[@aishwaryab673]

Hey TELUSKO, this was my first comment on KZbin because I was such an introvert to even make a comment, The way you teach I admire a lot and this video is incredible and it paves me to think of exploring all your courses!!!! Thanks again Telusko !!

[@Makbang-b9b]

In KZbin they don't reavel your identity so what happened if you are an introvert or extrovert Sorry if there is any grammatical mistakes

[@rohithvarma6763]

probably the best java teacher in the world

[@Shubham-fk4is]

It was easy in Python, but unable to understand in Java.

[@shabby_sakshi]

Yessss 😫

[@HPR2004...]

Frst understand how to do in java, then understand in python and then do there

[@MuthuAnushya]

Hey vera level bro 🎉 i can understand concepts very well it's my third days of java coding journey ,i continuously watching your tutorial and i follow ur tutorial only🎉.thank you 🎉🎉

[@chichhasquad2342]

Never been this much easy. Hatts off bro .

[@mosshead_vinsmoke]

I really appreciate you took the time to actually explain why the syntax works the way they are unlike others who just tell us do this Calculator obj = new Calculator(); and not explain what each is and does

[@nareshgajula]

Good but difficult for the beginners to understand the depth of your explanation!

[@chinyamaraphael-sp6wt]

I don't know how I can express myself. We did objects with my lecturer but I did not understand what he was saying until I found this video. You are a redeemer. ❤

[@fezaiozcan2227]

absolutely best tutorials about Java! thanks:)

[@Salimuamiri-c3h]

Congratulation you made java so easy in this short concept of object and class in java💯

[@rahulmansarowar1430]

your all videos is excellent! i wish i had found this collection years ago.❤

[@91-ritikjain36]

sir you are the best teacher sir plzz create a new series on jsp and servlet

[@prasantdas587]

You are an amazing instructor. It’s not just how to write the code but why to do it certain way.. brilliant..

[@akankshamishra1262]

Hi, Thanks a lot for excellent explanation, very understandable to beginners, I'm learning java for automation selenium with your video.💯

[@NoMadMediaProductions]

I really like your tutorial videos. This is like excel VBA (back in the days) where you could import a sub from a different sheet.

[@big-tech-solution]

Am enjoying every bit of these lessons......Kudos

[@MADDILAKSHMINARAYANA]

it was an excellent explanation. Very understandable to beginners.

[@mango-strawberry]

Literally perfect explanation

[@himanshu5838]

literally Legend ! I've purchased a paid course but i learn more there

[@TheSpeaker7738]

the int n1 and int n2 is storing the value of num1 and num2 for printing the output then why we have to initialize int a in class calculator what is it helping us in? is it helping us to store n1 and n2 value or anything else? ...... and the video was really helpful and understandable😇

[@underflo43tky]

Did we already go over methods? I understand this but maybe we didnt study methods much. Also explaining the difference between objects classes and methods would be useful. So is an object an instance of a class comprised of methods and variables? I understand these from studying before but the teachers really didnt explain so well. This is a good example and well explained but I think its a big leap for people who do not have any background. For me this is great. Thanks. I enjoy your tutorial.

[@shobhashobha2614]

Hi sir Which language is best for preparing dsa?

[@DevilGaming-bl1og]

Html

[@RK_Universe]

can't find main(String[]) method in class-How to solve the issue.Pls comment sir.

[@photolab6712]

superb lecture...

[@agilan1546]

Why are we creating a variable int a in the calculator class?

[@bandarisailikhitha9865]

Thanks navin, you are awesome

[@nandasiddiksha5534]

how to get user input?? Instead of assigning values to variables..

[@__sam_danielW]

We have to import scanner so that we can get the input from the user

[@rsvcreations7450]

sir when i am trying this i am getting error that "can't find main method in calculator class"

[@kanushagrawal7192]

why are we using diffrent classes for adding where it can be done easily in one class only??? why to complicate things??? and also did not understand anything rest all the videos were superb but i dont know why

[@md.ikramulislam9708]

for explaining the concept

[@kirubasathish3683]

sir we can add the number like this also sir? class Calculator{ int a; public int add() { System.out.println("add"); return 12 + 12; } } public class java1 { public static void main(String a[]) { Calculator calc = new Calculator(); int result = calc.add(); //int result = num1 + num2; System.out.println(result); } } and good explanation sir

[@kartheekk2380]

can you please explain 2nd line why we have to mention int a; please

[@Wake_up_to_reality_143]

​​​​@@kartheekk2380bro we are not using a he just shows how to declaration a data type in class

[@malvikaambastasquestx5965]

Yes, this will work.

Good explanation!

[@chaitanyathorat8429]

Perfectooo👌👌

[@timsy4401]

this video is not much clear

[@divakarpareek9466]

@telusko -- I must say your previous Java series of 6 hrs was much better then this one. I have come to 22nd video, in almost each video you are struggling to put clear example and changing in between that's frustating . It should be pre prepared.

[@abdulbasith3818]

Can you pls mention that vedio

[@abdulbasith3818]

For me it is little bit tuff

[@pinkeykumari1312]

my java file created but class not loaded then what to do?

[@pydisettymahesh9655]

it is an exaple of inheritance

[@ourera2279]

does anyone know where are the pratice questions for these ?

[@tekkishort9018]

U need to redo this part all parts were clear and concise until this video it's very bad redo it

[@rutulkarbhari4963]

not working for me even if I have the same codes as you. Giving - error: can't find the main(String[]) method in class: Calculator. Solution?

[@naveenrajanaveen6462]

Put (String args[]) instead of (String []) You want to give a name like args, abc, etc..

[@rutulkarbhari4963]

@@naveenrajanaveen6462 was helpful. And i also wanted to thank you sir🙏.

[@miethrayan]

​@@naveenrajanaveen6462 but it shows error in main method

[@Ashishhh0]

define calculator class after the hello class, then it will work fine@@miethrayan

[@ivanaleksic1364]

How did you spawn everything on the screen at start ? lol why you not type when we see?

[@_Deepak__Verma]

Instead of creating classes can't we make a complex function that works exactly the same way then why use class

[@msai4856]

Bro when ur explaining explain from zero . Ur explanation is like ur teaching to intermediate level students.

[@nprince411]

tqs sir

[@ajkumar0063]

can u pls explain class and object again this videos are confusing🤔🤔

[@RaghavendraMalager]

Please try and use relevant examples while explaining, using examples which are in no way connected to the topic makes understanding difficult for us. The Python course was very good, but this playlist seems to be derailed of its objective of making things easier for us.

[@sheiduwgwjd]

Confusing

[@manojm1853]

2:57 my iPhone says the same

[@hrishikeshmukherjee813]

Super

[@sonaligaikwad-zo5ds]

But in calculator class main method is not declare

[@vishwajeetdalvi]

Need to declare it only once, and you can do it any class.

[@AnuragRawat01]

Thank u so much 💯❤️
