Question

Java Please

Source Only

Program 3: Distance calc. This question is fairly straightforward. Design (pseudocode) and implement (source code) a program to compute the distance between 2 points. The program prompts the user to enter 2 points (X1, Y1) and (X2, Y2). The distance between 2 points formula is: Square_Root [(X2 – X1)^2 + (Y2 – Y1)^2] Document your code, properly label the input prompts, and organize the outputs as shown in the following sample runs.

import java.util.Scanner;

public class ProblemThree {


    public static void main(String[] args) {

        // scanner object to accept user input
        Scanner scanner = new Scanner(System.in);

        // create four variables
        double x1, y1, x2, y2;

        // get x1 and y1 from user
        System.out.print("Enter X1: ");
        x1 = scanner.nextDouble();
        System.out.print("Enter Y1: ");
        y1 = scanner.nextDouble();

        // get x2 and y2 from user
        System.out.print("Enter X2: ");
        x2 = scanner.nextDouble();
        System.out.print("Enter Y2: ");
        y2 = scanner.nextDouble();

        //calculate distance using Math.sqrt() method
        double distance = Math.sqrt((x1-x2)*(x1-x2) + (y1-y2)*(y1-y2));

        //display distance
        System.out.println("Distance: "+distance);
    }
}
