PLEASE HELP! Converting numbers into real words

Question

I am faced with a problem. I need to create a prorgram that will convert a number ex. 156 into the word "one hundred fiftysix" This program will need to handle numbers up to 999 999 999.
If someone has a program similar to this or is willing to assist a newbie programmer, your assistance would be appreciated.
Also source code is preffered, prefferbly with c as the console.
Thanks again

Here is my most up to date code
I also forwarded you a copy of my code
import hsa.Console;
public class ConvertingWordsToNumbers
private static int convertingFromOneToNineteen (String numberString)
String oneToNineteenInWords [] = {"", "one ", "two ", "three ", "four ", "five ", "six ", "seven ",
"eight ", "nine ", "ten ", "eleven ", "twelve ", "thirteen ", "fourteen ", "fifteen ",
"sixteen ", "seventeen ", "eighteen ", "nineteen "};
int oneToNineteenInNumbers [] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19};
int total = 0;
//Checking for each word and adding it to each total
for (int pos = 1 ; pos <= oneToNineteenInWords.length ; pos++)
if (numberString.indexOf (oneToNineteenInWords [pos]) >= 0)
total += oneToNineteenInNumbers [pos];
numberString = numberString.substring ((numberString.indexOf (oneToNineteenInWords [pos])));
return total;
return total;
private static int convertingFromTwentyToNinety (String numberString)
String twentyToNinetyInWords [] = {"", "", "twenty", "thirty", "fourty", "fifty", "sixty", "seventy",
"eighty", "ninety"};
int twentyToNinetyInNumbers [] = {0, 0, 20, 30, 40, 50, 60, 70, 80, 90};
int total = 0;
//Checking for each word and adding it to each total
for (int pos = 1 ; pos <= twentyToNinetyInWords.length ; pos++)
if (numberString.indexOf (twentyToNinetyInWords [pos]) >= 0)
total += twentyToNinetyInNumbers [pos];
numberString = numberString.substring ((numberString.indexOf (twentyToNinetyInWords [pos])));
return total;
return total;
public static void main (String [] args)
Console c = new Console ("ConvertingWordsToNumbers");
//Variable Declaration
String numberString, millions, thousands;
String keyWords [] = {"million", "thousand"};
//User Input
c.println ("Please enter the number (in words) that you wish to convert: ");
numberString = c.readLine ();
numberString = numberString.toLowerCase ();
//Sectioning the millions and thousands
if (numberString.indexOf (keyWords [0]) > 0)
millions = numberString.substring (0, (numberString.indexOf (keyWords [0])));
c.println (millions);
c.println (convertingFromOneToNineteen (millions) + convertingFromTwentyToNinety (millions));
if (numberString.lastIndexOf (keyWords [1]) > 0)
thousands = numberString.substring ((numberString.indexOf (keyWords [0]) + 8),
(numberString.indexOf (keyWords [1])));
c.println (thousands);
c.println (convertingFromOneToNineteen (thousands) + convertingFromTwentyToNinety (thousands));
else if (numberString.lastIndexOf (keyWords [1]) > 0)
thousands = numberString.substring (0, (numberString.indexOf (keyWords [1])));
} // main method
} // ConvertingWordsToNumbers class
