Answer 1

I couldn't resist. This is aboves answer in two lines (the ones that do all the work)

private static TextFormatter new3DecimalFormatter(){
        Pattern decimalPattern = Pattern.compile("-?\\d*(\\.\\d{0,3})?");
        return new TextFormatter<>(c -> (decimalPattern.matcher(c.getControlNewText()).matches()) ? c : null );
}
