format float number in Java (#.###.##)

Question

I'd like to format float numbers in a pretty manner like so:

1432.432342003 to 1.432,43

I can format it from 1432.432342003 to 1432,43 loike so:

 DecimalFormat decimalFormat = new DecimalFormat("#.##");
 String pretyStr = decimalFormat.format(input);

so how to achieve this, maybe there is a easy way like #.###.## - I don't want to take int part aside and float part aside

What you want is called a thousands separator, in english-speaking countries the usual format is 12,345,678.90

You may use the following format with DecimalFormat: ###,###.### The result of 123456.789 with this format shoudl be 123,456.789

You can find more information on DecimalFormat here

EDIT1: Example

 DecimalFormat decimalFormat = new DecimalFormat("###,###.##");

The format you're looking for is

DecimalFormat decimalFormat = new DecimalFormat("#,###.##");

But be careful, separators may change with your locale, and you may need to use a NumberFormat to control that

I got it like so:

  public static String getPrettyPrintVal(double input){
    final DecimalFormat decimalFormat = new DecimalFormat("###,###.###", DecimalFormatSymbols.getInstance(Locale.GERMANY));
    return decimalFormat.format(input);
}

3214234.234 ==> 3.214.234,234
