Thread: Comission Calculator not performing

Hi everyone. There doesn't seem to be an error on this IDE convertion calculator. Its the actual exercise Java offers to beginners. When I enter the digits though, I get this error message : run:
Exception in thread "AWT-EventQueue-0" java.lang.UnsupportedOperationException: Not supported yet.

Would you share with me the line containing the error ? I'm using Netbeans and not getting any error message.
thanks

In Netbeans IDE the editor window is not showing any error symbol may be Netbeans is not able to scan these lines, but in eclipse is properly showing the error in the above mentioned lines.
If you want to see the error in Netbeans IDE then first run your project in debug mode (use Ctrl + F5) then the IDE ig going to show you errors.

Hope this help you out.
