HI FRIENDS THIS IS A VERY SIMPLE PROGRAM THAT WILL CONVERT DECIMAL NUMBER TO IT'S EQUIVALENT AMOUNT IN WORDS.
import java.util.Scanner;
public class NumToWord {
String string;
String st1[] = { "", "one", "two", "three", "four", "five", "six", "seven","eight", "nine", };
String st2[] = { "hundred", "thousand", "lakh", "crore" };

"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);
}

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) {

pass(word);
}

break;
}
n++;
}
return string;
}
public void pass(int number) {
int word, q;
if (number < 10) {
show(st1[number]);
}
if (number > 9 && number < 20) {

}

}
}
public void show(String s) {

st = string;
string = s;
string += st;
}
public static void main(String[] args) {
NumToWord w = new NumToWord();
try {

System.out.print("Enter Number: ");
String num = input.nextLine();
int num2 = 0;

}

* CONVERT ALL DECIMAL WITH FRACTIONAL PART AS WELL AS MINUS VALUE.
