Converting Number to Word

[Ankita Jha]

Hello ranchers,

In my application i a need which will convert number to Word.
Problem is ,When i have whole number like (10000 or 2260) etc,it works properly.
Byt i have some number like 158.32 then it shld be read as "One hunderd fifty eight and thirty two paise" but it read the number as "Fifteen thousand eight hundred and thirty two"

Im pasting my code below.Any help wil be appreciated.Thanks in advance.

  import java.text.DecimalFormat;

One problem in your code what I could notice is in

  
private String cleanNumber( String number ){
String cleanedNumber = "";

cleanedNumber = number.replace( '.', ' ' ).replaceAll( " ", "" );
//the above line will remove the . character means if the number is 123.45, it becomes 12345
  

I have not went through your entire code but probably calling the convertNumber function twice might solve your requirement

Thanks Swastik Dey
Got it working

[salvin francis]

program can be made much more simpler:

eg:

String units[]=new String[]{"Zero","One","Two","Three","Four","Five","Six","Seven","Eight","Nine"};

so units[4] would return "Four", I dont see why you require so many switch cases etc.
