Question

Write the program to compute the distance between two points. Recall that the distance between the two points (x1, y1) and (x2, y2) is computed by taking the square root of the quantity (x1 - x2)^2 + (y1 - y2)^2. 1. Declare variables for two points coordinates as double 2. Declare variable for the distance 3. Create Scanner object 4. Prompt first point and assign it to the variable using nextDouble() 5. Prompt second point and assign it to the variable using nextDouble() 6. Compute the distance 7. Print out the answer

Explanation / Answer

Code:

import java.util.*;

class DistanceBwPoint

{

public static void main(String arg[])

{

double x1,x2,y1,y2; //declaring point co-ordinates variables

double distance; //declaring distance

Scanner sc=new Scanner(System.in); //creating scanner object

System.out.println("enter x1 for point-1:");

x1=sc.nextDouble();

System.out.println("enter y1 for point-1:");

y1=sc.nextDouble();

System.out.println("enter x2 for point-2:");

x2=sc.nextDouble();

System.out.println("enter y2 for point-2:");

y2=sc.nextDouble();

distance=Math.sqrt((x2-x1)*(x2-x1) + (y2-y1)*(y2-y1)); // finding distance

System.out.println("distance between"+"("+x1+","+y1+"),"+"("+x2+","+y2+") is : "+distance); //printing answer

}

}
