How to print formatted BigDecimal values?

I have a BigDecimal field amount which represents money, and I need to print its value in the browser in a format like $123.00, $15.50, $0.33.

How can I do that?

(The only simple solution which I see myself is getting floatValue from BigDecimal and then using NumberFormat to make two-digit precision for the fraction part).

 BigDecimal pi = new BigDecimal(3.14);
 BigDecimal pi4 = new BigDecimal(12.56);

 System.out.printf("%.2f",pi);

// prints 3.14

System.out.printf("%.0f",pi4);

// prints 13

Similar to answer by @Jeff_Alieffson, but not relying on default Locale:

Use DecimalFormatSymbols for explicit locale:

DecimalFormatSymbols decimalFormatSymbols  = DecimalFormatSymbols.getInstance(new Locale("ru", "RU"));

Or explicit separator symbols:

DecimalFormatSymbols decimalFormatSymbols = new DecimalFormatSymbols();
decimalFormatSymbols.setDecimalSeparator('.');
decimalFormatSymbols.setGroupingSeparator(' ');

Then:

new DecimalFormat("#,##0.00", decimalFormatSymbols).format(new BigDecimal("12345"));

Result:

12 345.00

I know this question is very old, but I was making similar thing in my kotlin app recently. So here is an example if anyone needs it:

val dfs = DecimalFormatSymbols.getInstance(Locale.getDefault())
val bigD = BigDecimal("1e+30")
val formattedBigD = DecimalFormat("#,##0.#",dfs).format(bigD)

Result displaying $formattedBigD:

1,000,000,000,000,000,000,000,000,000,000
