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

Re: I need some help
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 ) ;
}

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