import java.util.*; //Importing util for Scanner public class Pythagoras { public static void main(String[] args) { Scanner MyScan = new Scanner(System.in); //Initializing our scanner System.out.println("This program will calculate the length of the hypotenuse for you."); System.out.println("Enter the first side:"); //Asks user to input the first side double side1 = MyScan.nextDouble(); //Scans the input and stores in 'side1' System.out.println("Enter the Second side:"); //Asks user to input the second side double side2 = MyScan.nextDouble(); //Scans the input and stores in 'side2' double hypotenuse = Math.pow(side1, 2) + Math.pow(side2, 2); //First step is to make hypotenuse=side1^2+side2^2 hypotenuse = Math.sqrt(hypotenuse); //Find the square root of the above calculated hypotenuse System.out.println("The hypotenuse is: " + hypotenuse); //Prints the correct hypotenuse } } |
