Computing Distance
The file Distance.java contains an incomplete 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. The
program already has code to get the two points as input. You need to add an assignment statement to compute the distance
and then a print statement to print it out (appropriately labeled). Test your program using the following data: The distance
between the points (3, 17) and (8, 10) is 8.6023... (lots more digits printed); the distance between (-33,49) and (-9, -15) is
68.352....
// ************************************************************
// Distance.java

// Computes the distance between two points
// ************************************************************
import java.util.Scanner;
public class Distance
{
public static void main (String[] args)
{
double x1, y1, x2, y2; // coordinates of two points
double distance;
// distance between the points
Scanner scan = new Scanner(System.in);
// Read in the two points
System.out.print ("Enter the coordinates of the first point " +
"(put a space between them): ");
x1 = scan.nextDouble();
y1 = scan.nextDouble();
System.out.print ("Enter the coordinates of the second point: ");
x2 = scan.nextDouble();
y2 = scan.nextDouble();
// Compute the distance
// Print out the answer
}
}
