Now, I think,
In java utilities is not available.

But you can create utilities for solve this problem.

Example for solve this problem

 class EnglishDecimalFormat {
  private static final String[] majorNames = {
    "",
    " thousand",
    " million",
    " billion",
    " trillion",
    " quadrillion",
    " quintillion"
    };
 
  private static final String[] tensNames = {
    "",
    " ten",
    " twenty",
    " thirty",
    " fourty",
    " fifty",
    " sixty",
    " seventy",
    " eighty",
    " ninety"
    };
 
  private static final String[] numNames = {
    "",
    " one",
    " two",
    " three",
    " four",
    " five",
    " six",
    " seven",
    " eight",
    " nine",
    " ten",
    " eleven",
    " twelve",
    " thirteen",
    " fourteen",
    " fifteen",
    " sixteen",
    " seventeen",
    " eighteen",
    " nineteen"
    };
 
 private String convertLessThanOneThousand(int number) {
    String soFar;
 
    if (number % 100 < 20){
        soFar = numNames[number % 100];
        number /= 100;
       }
    else {
        soFar = numNames[number % 10];
        number /= 10;
 
        soFar = tensNames[number % 10] + soFar;
        number /= 10;
       }
    if (number == 0) return soFar;
    return numNames[number] + " hundred" + soFar;
}
 
public String convert(int number) {
    /* special case */
    if (number == 0) { return "zero"; }
 
    String prefix = "";
 
    if (number < 0) {
        number = -number;
        prefix = "negative";
      }
 
    String soFar = "";
    int place = 0;
 
    do {
      int n = number % 1000;
      if (n != 0){
         String s = convertLessThanOneThousand(n);
         soFar = s + majorNames[place] + soFar;
        }
      place++;
      number /= 1000;
      } while (number > 0);
 
    return (prefix + soFar).trim();
}
 
public static void main(String[] args) {
    EnglishDecimalFormat f = new EnglishDecimalFormat();
    System.out.println("*** " + f.convert(0));
    System.out.println("*** " + f.convert(1));
    System.out.println("*** " + f.convert(16));
    System.out.println("*** " + f.convert(100));
    System.out.println("*** " + f.convert(118));
    System.out.println("*** " + f.convert(200));
    System.out.println("*** " + f.convert(219));
    System.out.println("*** " + f.convert(800));
    System.out.println("*** " + f.convert(801));
    System.out.println("*** " + f.convert(1316));
    System.out.println("*** " + f.convert(1000000));
    System.out.println("*** " + f.convert(2000000));
    System.out.println("*** " + f.convert(3000200));
    System.out.println("*** " + f.convert(700000));
    System.out.println("*** " + f.convert(9000000));
    System.out.println("*** " + f.convert(123456789));
    System.out.println("*** " + f.convert(-45));
    /*
    *** zero
    *** one
    *** sixteen
    *** one hundred
    *** one hundred eighteen
    *** two hundred
    *** two hundred nineteen
    *** eight hundred
    *** eight hundred one
    *** one thousand three hundred sixteen
    *** one million
    *** two million

    }

How to use

 You can handle "dollar and cent" conversion by calling the "convert" method two times. 
 
String phrase = "12345.67" ;
Float num = new Float( phrase ) ;
int dollars = (int)Math.floor( num ) ;
int cent = (int)Math.floor( ( num - dollars ) * 100.0f ) ;
 
String s = "$ " + f.convert( dollars ) + " and " + f.convert( cent ) + " cents" ;
 
 
 

This will help you.

Thanks Somkiat for quick reply, I will give it a try.

btw, do you know where I can find free online Java resources (re. ready-to-use utilities class) on the Net? my background is in VB so it's will save time for me rather implement/re-write them in Java myself.
thanks again
Tony
