Can anyone help? Converting numbers to words?

[wavo7]

Hey all,
Well, I'm stuck and I don't know what to do. I need to have this thing done by tomorrow, I feel like I am on the right track but can't quite finish it. I need to account for numbers all the way up to 1 billion. I have numbers 0 -99 taken care of. Does ANYONE have any suggestions or some help on my code to extend the functionality??
PLease.
Here's what I have:
import java.io.*;
import java.util.*;
import java.lang.*;


public class WordNumbers
{
public static void main(String[] args) throws IOException
{
final String quitString = "done";
String inputString;
int firstNumber, counter;

BufferedReader input =
new BufferedReader(new InputStreamReader(System.in));

System.out.println("Enter "+quitString+" when finished"

String numberWords[] = {"one","two","three","four","five","six","seven",
"eight","nine","ten","eleven","twelve","thirteen",
"fourteen","fifteen","sixteen","seventeen","eighteen",
"nineteen"};
String tenWords[] = {"twenty","thirty","fourty","fifty","sixty","seventy",
"eighty","ninety"};
String bigWords[] = {"hundred","thousand","million","billion","trillion"};

inputString = input.readLine();

while (!inputString.equals(quitString))
{
firstNumber = Integer.parseInt(inputString);

if(firstNumber < 0)
{
System.out.println(&quot;negative &quot; + numberWords[firstNumber - 1]);
}

while (firstNumber > 0)
{
if(firstNumber >=1000000 && (firstNumber <=9999999))
{
System.out.println(bigWords[2]);
}
else
if(firstNumber >= 1000 && (firstNumber <= 9999))
{
System.out.println(bigWords[1]);
}
else
if(firstNumber > 99 && (firstNumber <= 999))
{
System.out.println(bigWords[0]);
}
else
if(firstNumber < 20)
{
System.out.println(&quot;You entered &quot; + numberWords[firstNumber - 1]);
}
else
{
int unitsNo = firstNumber % 10 ;
int decNo = firstNumber/10;
int unit2 = firstNumber % 100;
int dec2 = firstNumber/100;

if( unitsNo == 0 )
{
System.out.println(&quot;You entered &quot; + tenWords[ decNo - 2 ]);
}

if( unitsNo > 0)
{
System.out.println(&quot;You entered &quot; + tenWords[ decNo - 2 ] + &quot; &quot; + numberWords[ unitsNo - 1]);
}
else
if( unitsNo > 9)
{
System.out.println(&quot;hahah&quot;
}
}
firstNumber = -1;
}

if(firstNumber == 0)
{
System.out.println(&quot;You entered zero&quot;
}
inputString = input.readLine();
}
}
}
