import java.util.Locale;
import java.text.NumberFormat;
public class DefaultNumberFormatters {
public static void main(String[] args){
double value = 1566789.785 ;
// Default locale
printFormatted(Locale.getDefault(), value);
// Indian locale
// (Rupee is the Indian currency. Short form is Rs.)
Locale indianLocale = new Locale("en", "IN");
printFormatted(indianLocale, value);
}
public static void printFormatted(Locale locale, double value) {
// Get number and currency formatter
NumberFormat nf = NumberFormat.getInstance(locale);
NumberFormat cf = NumberFormat.getCurrencyInstance(locale);
System.out.println("Formatting value: " + value +
" for locale: " + locale);
System.out.println("Number: " + nf.format(value));
System.out.println("Currency: " + cf.format(value));
}
