Hi Friend,

Try the following code:

import java.util.*;

public class NumToWords {
String string;
String st1[]={"","one","two","three","four","five","six","seven","eight","nine",};
String st2[]={"hundred","thousand","lakh","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 ;
}
public static void main(String[] args) {
NumToWords w=new NumToWords();
Scanner input=new Scanner(System.in);
System.out.print("Enter Number: ");
int num=input.nextInt();
String inwords=w.convert(num);
System.out.println(inwords);
}
}
Thanks
