How To Show Negative Numbers Using Brackets With NumberFormatter In Java

If you want to use parentheses around your negative numbers, you can do it in Java like this:

NumberFormat formatter = NumberFormat.getCurrencyInstance(locale);
if (formatter instanceof DecimalFormat) {
    DecimalFormat f = (DecimalFormat) formatter;
    f.setNegativePrefix("(" + f.getPositivePrefix());
    f.setNegativeSuffix(")");
}
String output = formatter.format(value);

This snippet will retain the localised currency formatting set by NumberFormat.
