How to you write a java program using the distance formula?
import java.util.Scanner;
public class Distance
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter first two points (x1, y1) :");
double x1 = input.nextDouble();
double y1 = input.nextDouble();
System.out.print("Enter second two points (x2, y2) :");
double x2 = input.nextDouble();
double y2 = input.nextDouble();
double distance = Math.pow(((x2  x1)(x2  x1) + (y2  y1)(y2  y1)), 0.5);
System.out.print("The distance of the two points is " + distance); //I'm using JGRASP AND my error is here!
}
}

Distance.java:14: error: ')' expected

Re: How to you write a java program using the distance formula?
Count your opening and closing parenthesis. You should have the same number of each.

Re: How to you write a java program using the distance formula?
It has to do with the fact hat you can't multiply in Java like (x2x1)(x2x1). It has to be (x2x1)*(x2x1).
And BTW, there is a square root method in the Math class.
