How to convert number to words in java

Question

We currently have a crude mechanism to convert numbers to words (e.g. using a few static arrays) and based on the size of the number translating that into an english text. B

I think this may help you...programme is very simple and works fine

import java.util.*;

public class NumberToWord

{
    public void pw(int n, String ch)
    {
        String one[] = {

        " ", " one", " two", " three", " four", " five", " six", " seven",
                " eight", " Nine", " ten", " eleven", " twelve", " thirteen",
                " fourteen", "fifteen", " sixteen", " seventeen", " eighteen",
                " nineteen" };
        String ten[] = { " ", " ", " twenty", " thirty", " forty", " fifty",
                " sixty", "seventy", " eighty", " ninety" };
        if (n > 19) {
            System.out.print(ten[n / 10] + " " + one[n % 10]);
        } else {
            System.out.print(one[n]);
        }
        if (n > 0)
            System.out.print(ch);

    }
    public static void main(String[] args)

    {
        int n = 0;
        Scanner s = new Scanner(System.in);
        System.out.print("Enter an integer number: ");
        n = s.nextInt();
        if (n <= 0)
            System.out.print("Enter numbers greater than 0");
        else
        {
            NumberToWord a = new NumberToWord();
            System.out.print("After conversion number in words is :");
            a.pw((n / 1000000000), " Hundred");
            a.pw((n / 10000000) % 100, " crore");
            a.pw(((n / 100000) % 100), " lakh");
            a.pw(((n / 1000) % 100), " thousand");
            a.pw(((n / 100) % 10), " hundred");
            a.pw((n % 100), " ");
        }
    }
}
