Decimal separator in NumberFormat

Question

Given a locale java.text.NumberFormat:

NumberFormat numberFormat = NumberFormat.getInstance();

How can I get the character used as Decimal

Answer 1

The helper class DecimalFomatSymbols is what you are looking for:

DecimalFormat format = (DecimalFormat) DecimalFormat.getInstance();
DecimalFormatSymbols symbols = format.getDecimalFormatSymbols();
char sep=symbols.getDecimalSeparator();

To set you symbols as needed:

//create a new instance
DecimalFormatSymbols custom=new DecimalFormatSymbols();
custom.setDecimalSeparator(',');
format.setDecimalFormatSymbols(custom);

EDIT: this answer is only valid for DecimalFormat, and not for NumberFormat as required in the question. Anyway, as it may help the author, I'll let it here.
