I need some help

This is my first time in java. I was wondering if somebody could help me finish this. Thanks

Recall that the distance between two points (x1,y1) and (x2, y2) is compute by taking the square root of the quanity (x1 - x2)^ + (y1 - y2)^.
// *************************************************************
// 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

Usually I'd say "We don't do homeworks" but what the hell today is a happy day

Code:

---

  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() ;
    distance = Math.sqrt( ( x1 - x2 ) * ( x1 - x2 ) + ( y1 - y2 ) * ( y1 - y2 ) ) ;
    System.out.printf( "The distance between (%f,%f) and (%f,%f)=%f", x1, y1,
                      x2, y2, distance ) ;
  }

Oh, and by the way http://www.vbforums.com/ to the Forums ;)

Thank you very much

You could at least say, "Use code tags." ;)
