You're are really a great teacher. Most of the courses are expensive to learn which many people couldn't afford, but you're the only one man army who can teach us almost everything. Keep it up, keep doing this great work. God bless you.

Your contribution is just wow.
It is a evolution of coding in India

@@technicalsahilabbasi2171 thanks
😂😂😂😂😂😂What a joke
@@vkraj8735 joke nhi yr itne acche say explain krte hai harry sir agar inka jaise college ke teacher ho jaye too subko coding easy lagege ❤️🙏
Not only India also other country people who knows Hindi and multi languages🙂🙂
You should definitely not joke on people like these as they are damn rare🥺🥺🥺
Harry bhai I cant thank you enough. I am doing courses for Java fullstacks. Today they taught us the topic for 3 hours and I couldnt figure out why we use this thing. My professor replied to me that its used to access private variables. Bhai apne itna ache se explain kiya k why exactly we need to use it. We need teachers like you. I have learnt so much from you and I cant thank you enough. I cant even pay you back. I always like your video first before watching it. You are Great Brother.
Did you saw all of his videos and how good are you at coding now?
Dear Harry sometimes i thing u are out of this world 'cause u made my learning so easy that even my school teachers can't .
Did you saw all of his videos and how good are you at coding now

Hi Harry,
My name is V.Nandini. A Huge Fan of you from Telangana. I had started learning java from many sites and other youtube videos, but not at all satisfied and I had stopped learning them in between. To speak honestly, your channel and you are brilliant. It had solved many of my doubts. I had became efficient after doin many of your exercises, practise sets and following your notes mainly. I had accessed your entire java playlist too. Thankyou very much Harry!!!!
Answer ::::::::
class Circle{
private int radius;
public int getRadius(){
return radius;
}
public int setRadius(int r){
return radius=r;
}
public float area(){
return 3.14f*(radius*radius);
}
}
public class Main{
public static void main(String[] args) {
Circle cr = new Circle();
cr.setRadius(5);
System.out.println(cr.getRadius());
System.out.println(cr.area());
}
}
sorry to say this Nandini, but while setting the radius you don't have to use int, instead you should've used void..
ex: public void setRadius(int r){
radius = r;
}
public int getRadius(){
return radius;
}
Ps - Please correct me if I'm wrong
Wrong hai bhai
Tune method me condition nahi Diya hai check kerne ke liye
Aur pubic void setradius hota hai
Setter returns type nahi hai
Your teaching is a gift to this Generation !! thanks alot sir.
Bhai aap brilliant work kar rahe ho ,audience harry bhai itna hard work kar rahe hain ,plz yaar inko support karo❤️❤️🙏🙏.Bhai maine aapka sabse pahle 2:30 hours wala course complete kar liya ab iska baari hai.

Why are you use float and make code complicate. Simple use int enter radius and cut the remaning point value :)...
@@manjit0000 brother using float is usually a safer option alwayss
You are very hard working person
amazing lectures thank very much🤩🤩😍
Thanks sir for clearing our doubts ❤
HAPPY TEACHER'S DAY ❤ HARRY BHAIYA...learned a lot from you..🧡🤍💚

Sir jb bhi m koi book padhta hu usme naming conventions pr boht dhyaan diya jaata h aur samajhne me aasani hoti h isiliye aap bhi naming vagera thodi topic se related rha kro.
Like at 4:10 line 7 me aapne parameter me "String n" name rkha h jo ki topic se bilkul bhi related nhi h toh thoda names pr bhi dhyan diya kro🙏
It's just a suggestion to improve your content 😄.
Amazing java course
