Currency Formatting Canadian English and French

Question

I have a requirement to set the value based on the locale. I will get the locale either en_US or fr_FR

 String locale = object.getLocale();  //

Then based on the locale I need to define the currency. The currency format I need is defined under.

   Language            Example             Notes
   Canadian French     123.456.789,99 $    symbol is a suffix,'comma' for decimal
   Canadian English    $123,456,789.99      symbol is a prefix,'dot' for decimal

Currently I have form attributes which I directly set the values in my java class.

  ...
  Form form = new Form();
    // Stub data for generating a graph.
    formBean.setCurrOne("123.54");
    formBean.setCurrTwo("456.33");
          ....//before I set those attributes I need to place a check
              // for locale and format the currency accordingly.

Can you please help me with the format. Also there is a difference of , and a . in the currency format.

Answer 1

NumberFormat canadaFrench = NumberFormat.getCurrencyInstance(Locale.CANADA_FRENCH);
NumberFormat canadaEnglish = NumberFormat.getCurrencyInstance(Locale.CANADA);

BigDecimal amount = new BigDecimal("123456789.99");

System.out.println(canadaFrench.format(amount));
System.out.println(canadaEnglish.format(amount));

Result:

123 456 789,99 $
$123,456,789.99

If you really don't want to use the default format (with spaces as thousand separator rather than dots), then use

DecimalFormatSymbols symbols = ((DecimalFormat) canadaFrench).getDecimalFormatSymbols();
symbols.setGroupingSeparator('.');
((DecimalFormat) canadaFrench).setDecimalFormatSymbols(symbols);

See, this is all done for you by the NumberFormat class, provided you give it the proper locale. fr_FR means French of France, and not French of Canada. You need fr_CA for that. And en_US means English of the United States, and not English of Canada. You need en_CA for that.
