How to convert an int so as to return the string which is how we say the int

Question

I came across this interview question where the interviewer asked to write a function which will take an integer, say 123, and will return a string that would be how one would say that integer.In above case output should be "one hundred and twenty three".I have no idea how to solve these problems.Can anyone help in how to work out this problem? A pseudo code will be helpfull.

 public class YourNumberMyWord { 
        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 scanf = new Scanner(System.in); 
            System.out.println("Enter an integer number: "); 
            n = scanf.nextInt();

            if(n<=0) 
                System.out.println("Enter numbers greater than 0"); 
            else { 
                YourNumberMyWord a = new YourNumberMyWord(); 
                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)," "); 
            }
            }

    }
