    Default 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
    double distance = Math.pow((x2 - x1)(x2 - x1) + (y2 - y1)(y2 - y1), 0.5;
    ^

    Count your opening and closing parenthesis. You should have the same number of each.

    It has to do with the fact hat you can't multiply in Java like (x2-x1)(x2-x1). It has to be (x2-x1)*(x2-x1).
    And BTW, there is a square root method in the Math class.
