Numbers to text - OR help with ASP or DELPHI to JAVA
If you know delphi or ASP you might wanna check out the links in the bottom and help me translate it to Java...
I'd like help with a program that prints text instead of numbers eg.
123 = onehundredtwentythree
I have som ideas, but they seem way complex for my understanding and seems like more code than nessecary...
Thank you for any help and sorry for any language errors, I'm from Sweden
