Throwing Exception (s) in a multilingual (e.g. English and French) application

In my applications, I use Exception to control the flow.

I am using something like this:

throw new Exception("Unable to add new user, user already exist");

This method is perfect in a single language application. However, when I intend to make a multilingual application, I do not know what to do.

The previous line of code should display a message in the default language that the user is using.

What are the possible solutions?

//currentLanguage indicates what the language of the current session is.

exceptionString = lookupExceptionString(currentLanguage);
throw new Exception(exceptionString );
