Convert Currency Numbers to Words

Hi Guys,

In Some of your project, there may be requirement to convert currency in words.(i.e. 12.50 = Twelve Rupees Fifty Paise Only).
To fulfill such requirement, here I am showing the Java code that will take input from user for currency(in numbers) and convert it into words.


import java.util.Scanner;
public class ConvertMoneyToNumberMain {
public static void main(String args[]) {
String str2 = "";
NumToWords w = new NumToWords();
Scanner input = new Scanner(System.in);
System.out.print("Enter Money Amount(Rs.Ps): ");
String amt = input.next();
int rupees = Integer.parseInt(amt.split("\\.")[0]);
String str1 = w.convert(rupees);
str1 += " Rupees ";
int paise = Integer.parseInt(amt.split("\\.")[1]);
if (paise != 0) {
str2 += " and";
str2 = w.convert(paise);
str2 += " Paise";
}
System.out.println(str1 + str2 + " Only");
}
}


class NumToWords {
String string;
String st1[] = { "Zero", "One", "Two", "Three", "Four", "Five", "Six",
"Seven", "Eight", "Nine", };
String st2[] = { "Hundred", "Thousand", "Lac", "Crore" };
String st3[] = { "Ten", "Eleven", "Twelve", "Thirteen", "Fourteen",
"Fifteen", "Sixteen", "Seventeen", "Eighteen", "Ninteen", };
String st4[] = { "Twenty", "Thirty", "Fourty", "Fifty", "Sixty", "Seventy",
"Eighty", "Ninty" };


public String convert(int number) {
int n = 1;
int word;
string = "";
while (number != 0) {
switch (n) {
case 1:
word = number % 100;
pass(word);
if (number > 100 && number % 100 != 0) {
show("and ");
}
number /= 100;
break;
case 2:
word = number % 10;
if (word != 0) {
show(" ");
show(st2[0]);
show(" ");
pass(word);
}
number /= 10;
break;
case 3:
word = number % 100;
if (word != 0) {
show(" ");
show(st2[1]);
show(" ");
pass(word);
}
number /= 100;
break;
case 4:
word = number % 100;
if (word != 0) {
show(" ");
show(st2[2]);
show(" ");
pass(word);
}
number /= 100;
break;
case 5:
word = number % 100;
if (word != 0) {
show(" ");
show(st2[3]);
show(" ");
pass(word);
}
number /= 100;
break;
}
n++;
}
return string;
}


public void pass(int number) {
int word, q;
if (number < 10) {
show(st1[number]);
}
if (number > 9 && number < 20) {
show(st3[number - 10]);
}
if (number > 19) {
word = number % 10;
if (word == 0) {
q = number / 10;
show(st4[q - 2]);
} else {
q = number / 10;
show(st1[word]);
show(" ");
show(st4[q - 2]);
}
}
}


public void show(String s) {
String st;
st = string;
string = s;
string += st;
}
}

OUTPUT:
