Add this line after you create your formatter:

        formatter.setMinimumFractionDigits(3);

You could use DecimalFormat, check the link for further information on formatting patterns.

DecimalFormat decimalFormat = new DecimalFormat("$ #,##0.000");

System.out.println(decimalFormat.format(3.114));
System.out.println(decimalFormat.format(3.1146));
System.out.println(decimalFormat.format(123213143.1146));

It produces the following output:

$ 3.114
$ 3.115
$ 123,213,143.115

Without the need for manual rounding in your code.

please have a look to this tutorial from Oracle: http://docs.oracle.com/javase/tutorial/i18n/format/decimalFormat.html

And the following code

        //Locale
    DecimalFormatSymbols dfs = new DecimalFormatSymbols(Locale.US);


    dfs.setDecimalSeparator('.');
    dfs.setGroupingSeparator(',');
    DecimalFormat df = new DecimalFormat("###,###,###,###.000", dfs);

    return df.format(amount);
