import javax.swing.JOptionPane; public class Main { public static void main(String[] args) { double x; double y; double z; x = Double.parseDouble(JOptionPane.showInputDialog(null,"What is side x?")); y = Double.parseDouble(JOptionPane.showInputDialog(null,"What is side y?")); z = Math.sqrt((x*x)+(y*y)); JOptionPane.showMessageDialog(null,"Side z is "+z); } } I decided to try writing the same program by myself but using the GUI from the last lesson to see how well I understood all of the concepts taught so far. Worked well. Thanks Bro! :D

[@felexsabu2562]

@Bro Code Hey bro in 4:13 you type x but dont precede it with String. Is it ok to write a variable without adding its class. I just want to understand the reason of where one should add class.

[@andersburon1216]

i tried combining with the previous lesson to spice it up: import javax.swing.JOptionPane; public class Main { public static void main(String[] args) { double x = Double.parseDouble(JOptionPane.showInputDialog("Enter side x: ")); double y = Double.parseDouble(JOptionPane.showInputDialog("Enter side y: ")); double z; z = Math.sqrt((x*x)+(y*y)); JOptionPane.showMessageDialog(null, "The hypotenuse is: "+z); } }

First of all his videos are direct to point ... no bullshit Then his voice is so soothing Explains everything really smoothly Then lastly Better than paid courses... He values out time.. everthing is point to point Great work Bro Keep growing Love from India

[@abdalle3483]

Wow, this series is better than paid ones. thank you Boss a lot

[@BroCodez]

thanks for watching Abdalle

[@Golosovtalks]

I wasn't able to find anything useful in russian segment of youtube about java, so i made up my mind to look for something in english segment and i came across with you. i don't figure out almost 20-30 % of your speaking, buy you turned out more useful and informative than those guys) thanks great for your extremely hard work)

[@momomomo-lt5fs]

I'm a total beginner, I'm a career shifter, and I need to learn java. Thanks for this series I hope to learn what I need for java from this and so far it's very easy to understand concepts

[@sutofana]

hey,how is your career shifting going?

[@perezkirvygian9725]

I'm 16 years old right now, and I just learned the fundamentals of coding from another video to understand some of the terms ahead of time. I can say that it really helps when you explain things directly to the point. I've made a basic calculator for addition, multiplication, etc. (although I don't know how to combine all of them yet) just based on the lessons you taught on GUI introduction, arithmetic expressions, and user input. I just wanted to thank you for making this video. It's really helpful, coming from a guy in 2024.

i am not bored to watch and comment your videos. and smash the like button every time with a "detroit smash"

Thanks for the explanation. Very easy but very useful for a beginner like myself.

thanks for watching Vitor

You can also replace z value with Math.hypot(x, y) method (Java16). Thx for the vids, doing full course, pretty awesome so far!

[@ilanshlain8819]

Hey bro! I used what I learned from your GUI video and made this program into a GUI! import javax.swing.JOptionPane; public class Main { public static void main(String[] args){ double x; double y; double z; x = Double.parseDouble(JOptionPane.showInputDialog("Enter in size for side x")); //This is for side x. y = Double.parseDouble(JOptionPane.showInputDialog("Enter in size for side y")); //This is for side y. z = Math.sqrt((x*x) + (y*y)); JOptionPane.showMessageDialog(null, "The hypotenuse for your triangle is " + z); //This is for the hypotenuse. } } Thanks so much bro for making programming so much more enjoyable!

[@Daddy_D96]

Tried the same, thanks for the help.

[@pavelkvasnicka6856]

This is the best Java tutorial for beginners, so you can learn Java and English in one hit. Please keep going! I vote for Java advance tutorial. Thanks a lot Bro

[@yrtech-pk2lz]

I am a junior beginner. Sir thank you for this I learn a lot.

[@munawaraliaraiz8760]

Best playlist for beginners...❤️ Love ur videos Bro

[@bagyu333]

Or you can play with an other math method Math.pow: import javax.swing.JOptionPane; public class Main { public static void main(String[] args) { double a = Double.parseDouble(JOptionPane.showInputDialog("Enter side 'a': ")); double b = Double.parseDouble(JOptionPane.showInputDialog("Enter side 'b': ")); double c = Math.sqrt(Math.pow(a, 2) + Math.pow(b, 2)); JOptionPane.showMessageDialog(null, "The hypotenuse is: " + c); } }

I've always wanted to be able to calculate the hypotenuse of a triangle. Thx.

import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner sc = new Scanner(System.in); double p; double b; double h; System.out.println("Enter base: "); b = sc.nextDouble(); b = Math.pow(b, 2); System.out.println("Enter perpendicular: "); p = sc.nextDouble(); p = Math.pow(p, 2); h = b + p; h = Math.sqrt(h); System.out.println(h + "inches"); sc.close(); } } I paused the video and tried to solve the problem by myself and this what I've done. Different code but both giving the same results. Hoping that soon I can make a more efficient code like yours. BTW, I just started learning java and my dream is to be come a software dev 😅 ps: your video tutorials really helping me a lot. thankyou so much!

[@IceBeam93]

Thank you so much for these tutorials. Just to give you a hint why you cant get an answer of -10 as a root is because it is a negative number!

[@jilllin9776]

Thank you for making the series video for the beginner. That's really helpful.

7th. So you can use numbers to instantiate them with the Math function (round, floor, ceil, sqrt, abs, min, max). Thank you, ma Bro Sensei!

So we need to import math modules? because the functions like sqrt, abs, and max-min don't work, please advise!

You shouldn't need to import anything Math.something, is the M in Math capitalized?

Hello Mr. Bro, my IDE always gets errors even if I do not have any code written in it and it does not go away even if I delete my default package and remake it. The only way that I could remove that is by reinstalling the IDE and the JDE. Could you please tell me how to get away from that issue?

I did in a slightly different way but got the same results . . . import java.util.Scanner; public class Main{ public static void main(String[] args) { //|**Creating a program that will find the Hypotenuse of a triangle**|\\ double a; double b; double hypotenuse; Scanner ScannerInput = new Scanner(System.in); //tag 01 System.out.print("Enter the side A: "); a = Double.parseDouble(ScannerInput.next()); System.out.print("Enter the side B: "); b = Double.parseDouble(ScannerInput.next()); hypotenuse = Math.sqrt((a*a)+(b*b)); System.out.print("The hypotenuse is: "+hypotenuse); ScannerInput.close(); } }

Math.sqrt didn't work because you can't put a negative number in a root

When I tried to do "math." it would only show class and main string? any1 know why edit: Is it because the public class is named Math?
