convert number into words

[jayadan]

hey guys i did a program for converting number into words and i almost got through but my folks want it even possible for decimal numbers too buti couldnt make that possible and can anyone help me in this and i also attach the codes i did and if something is wrong let me know it

Thanks in advance guys:):):)

import java.util.Scanner;
public class NumberToWord 
{
	public static final String[] DIGITS = {"one", "two", "three", "four", "five",
		"six", "seven", "eight", "nine"};
	public static final String[] TENS = {null, "twenty", "thirty", "forty", "fifty",
		"sixty", "seventy", "eighty", "ninety"};
	public static final String[] TEENS = {"ten", "eleven", "twelve", "thirteen", "fourteen",
		"fifteen", "sixteen", "seventeen", "eighteen", "nineteen"};
	public static String wordifyNumber(int number) 
	{
		StringBuilder sb = new StringBuilder();
		int x = number / 100;
		if (x > 0) 
	{ 
		sb.append(DIGITS[x - 1] + " hundred");
	}
		x = number % 100;
		int tens = x / 10;
		if (tens > 0) 
	{ 
		if (sb.length() > 0) 
	{
		sb.append(" ");
	}
		if (tens > 1) 
	{
		sb.append(TENS[tens - 1]);
	} 
		else 
	{
		sb.append(TEENS[x - 10]);
		number = 0;
	}
	}
		x = number % 10;
		if (x > 0) 
	{ 
		if (sb.length() > 0) 
	{
		if (tens >= 2) 
	{
		sb.append("-");
	} 
		else 
	{
		sb.append(" ");
	}
	}
		sb.append(DIGITS[x - 1]);
	}
		return sb.toString();
	}
		public static void main(String[] args) 
	{
		Scanner scanner = new Scanner(System.in);
		while (true) {
		System.out.println("Enter a number (or -1 to quit): ");
		int number = scanner.nextInt();
		if (number == -1) 
	{
		break;
	} 
		else if (number == 0) 
	{
		System.out.println("Number = zero");
	} 
		else 
	{
		System.out.print("Number = ");
		if (number > 999) 
	{
		System.out.print(wordifyNumber(number / 1000) + " thousand");
		number = number % 1000;
		System.out.print(number > 99 ? ", " : " ");
	}
		System.out.println(wordifyNumber(number));
	}
	}
		System.out.println("Done.");
	}
}

Why can't you do it for decimal numbers? the logic is about the same, but you'll just need to accept a numeric type that is capable of taking decimal numbers, like float or double, and take into consideration the number of leading zeroes in your decimal part, too.

stultuske i did the same thing using double data type but i am getting error in all the append lines in the program and i tried all possible ways and i m out of ideas so seeking help from u guys...if possible u try replacing int to double...

[stultuske]

well, how about you show what you tried that didn't work. it'll be easier for us to determine if and (if so) what you did wrong.

[jayadan]

[stultuske this is what i tried and edited things as i told you earlier

import java.util.Scanner;
public class NumberToWord 
{
	public static final String[] DIGITS = {"one", "two", "three", "four", "five",
		"six", "seven", "eight", "nine"};
	public static final String[] TENS = {null, "twenty", "thirty", "forty", "fifty",
		"sixty", "seventy", "eighty", "ninety"};
	public static final String[] TEENS = {"ten", "eleven", "twelve", "thirteen", "fourteen",
		"fifteen", "sixteen", "seventeen", "eighteen", "nineteen"};
	public static String wordifyNumber(double number) 
	{
		StringBuilder sb = new StringBuilder();
		double x = number / 100;
		if (x > 0) 
	{ 
		sb.append(DIGITS[(int)((double)x - 1)] + " hundred");
	}
		x = number % 100;
		double tens = x / 10;
		if (tens > 0) 
	{ 
		if (sb.length() > 0) 
	{
		sb.append(" ");
	}
		if (tens > 1) 
	{
		sb.append(TENS[(int)((double)tens - 1)]);
	} 
		else 
	{
		sb.append(TEENS[(int)((double)x - 10)]);
		number = 0;
	}
	}
		x = number % 10;
		if (x > 0) 
	{ 
		if (sb.length() > 0) 
	{
		if (tens >= 2) 
	{
		sb.append("-");
	} 
		else 
	{
		sb.append(" ");
	}
	}
		sb.append(DIGITS[(int)((double)x - 1)]);
	}
		return sb.toString();
	}
		public static void main(String[] args) 
	{
		Scanner scanner = new Scanner(System.in);
		while (true) {
		System.out.println("Enter a number (or -1 to quit): ");
		double number = scanner.nextDouble();
		if (number == -1) 
	{
		break;
	} 
		else if (number == 0) 
	{
		System.out.println("Number = zero");
	} 
		else 
	{
		System.out.print("Number = ");
		if (number > 999) 
	{
		System.out.print(wordifyNumber(number / 1000) + " thousand");
		number = number % 1000;
		System.out.print(number > 99 ? ", " : " ");
	}
		System.out.println(wordifyNumber(number));
	}
	}
		System.out.println("Done.");
	}
}

[stultuske]

well, I get ArrayIndexOutOfBounds 49 and stuff like that, so you may want to recheck your code a bit.

stultuske i dont understand what your saying and i could execute it for some random nos but not all nos.....
