Write a program in Sun Java to convert a given number to words. The number must be input by the user. It may be as long as 4 digits. For example:
345 - Three hundred and forty five
1037 - One thousand three hundred and thirty seven
Make use of user defined functions and switch statement wherever neccessary.

Please do give a variable list, as in variable name, type, and its function. I do not know what is meant by 'program listing' but if you can, please give that too!

We arent allowed to use strings and arrays.

It's really really really urgent!! It may take you some time, but I'd be deeply, truly, sincerely gratified to you!!!!!! It's very very important!!!! Please help!!!!

Please email it on cutencrazylittlegirl@yahoo.co.in!!
Thank you!

String[] word0_9 = {"zero","one", "two", "three", "four", "five", "six", "seven", "eight", "nine" };

private String convertToWord(int number){

if(number>=0 && number<=9 )
{
return word0_9[number];
}
int temp=number;

String words="";

if(number >=11 && number <=19)
{
return word11_19[number-11];
}

number=number/10;
if(number!=0)
