"Digit Grouping" is messed up

Quote:Does the localization mentioned in the link simply change the input/output formats, or does it allow the source code itself to use the localizations?

You ask in the program code in which language your computer is configured and what should then be done depending on the system language actually set. The javac compiler checks in which language your computer is configured. The settings for the number separator are then actually taken into account. The input format itself is then not changed, the program can deal with the format if this format has been made known through localization.

Code:


    double d = 1.2345;
    Locale locde = new Locale("de", "DE");
    Locale locus = new Locale("en", "US");
    System.out.format(locde, "%.3f\n", d); // 1,235
    System.out.format(locus, "%.3f\n", d); // 1.235
