Scanner to read values from a file and Locale problems for nextDouble()

Hi everyone,

I'm quite puzzled as I need to read a configuration file in sequential mode (some lines are headers indicating the number of elements than we have elements themselves with their own attributes).
Fact is my default Locale uses ',' as decimal format separator (i.e: 12,3) while in my configuration files it's '.' (i.e: 12.3). By default it throws a java.util.InputMismatchException

I solved that by setting Locale.US to my scanner reference using the useLocale method but I'm wondering if it's the only choice I have (since I don't find methods to change just the decimal format separator).

Thanks for your explanations
