Thread: Average Won't Work

import java.text.DecimalFormat;
import java.util.Scanner;
public class Average {
   public static void main (String[] args) {
      int sum = 0, value, count = 0;
      double average;
      Scanner scan = new Scanner (System.in);
      System.out.print ("Enter an integer (0 to quit): ");
      value = scan.nextInt();
      while (value != 0)  // sentinel value of 0 to terminate loop
      {
         count++; 
         sum += value;
         System.out.println ("The sum so far is " + sum);
         System.out.print ("Enter an integer (0 to quit): ");
         value = scan.nextInt();
      }
      System.out.println ();
      System.out.println ("Number of values entered: " + count);
      average = (double)sum / count;
      DecimalFormat fmt = new DecimalFormat ("0.###");
      System.out.println ("The average is " + fmt.format(average));
   }
}

Found this from one of my projects, you could use it if you want.

Why won' the average work? when i enter 10 for the first number, then 20 for the second number, it returns an average of 5.

This is as opposed to saying - here's the answer (in fact doing the latter doesn't help in learning the important skill of problem solving, and in many cases would be against academic rules). This is more clearly discussed in the following article: http://www.javaprogrammingforums.com...n-feeding.html

Post your new code. Given the code fed to you above, we can only guess what the code you are using looks like (and please keep in mind my note to D.K. above)

Alright.
