Question

I am creating a program where a user will enter in a price amount. And then the program will determine how many 20, 10, 5, 1, etc.. they get back. I keep getting "error: unexpected type" in my findValue method. Not too sure why I am getting this. There also might be more bugs in there that I am not aware of because it wont compile. Any help is appreciated.

Here is my code:

import java.util.Scanner;
public class prac1
{
   public static void main (String [] args)
   {
       double[] dArray = new double[]{20, 10, 5, 1, .25, .10, .05, .01};
       String [] stringArray = new String [] {" twenty-dollar bill(s)," , " ten-dollar bill(s)," , " five-dollar(s)," , " one-dollar bill(s)," , " quarter(s)," , " dime(s)," , " nickel(s)," , " penny(ies),"};
       double amount;
       Scanner keyboard = new Scanner(System.in);
       System.out.print("Please enter an amount: ");
       amount = keyboard.nextDouble();
       amount = (int) (amount* 100 + 0.5)/100.0;
       System.out.print("You need the following:");
       int i =0;
       for(; i < 8; i++)
       {
           System.out.println(findValue(amount, dArray[i]) + stringArray[i]);
       }
   }
   public static double findValue(double some, double value)
   {
       int thing = 0;
       int change = 0;
       ((int)some / (int)value) = thing;
       ((int)some - ((int)value * thing)) = change;
       return change;
   }
}
