I need to write currency values like $35.40 (thirty five dollars and forty cents) and after that, i want to write some "****"

so at the end it will be: thirty five dollars and forty cents********* in a maximun of 100 characters

I've asked a question about something very likely but I couldn't understand the main command.

String format = String.format("%%-%ds", 100);
String valorPorExtenso = String.format(format, new Extenso(tituloTO.getValor()).toString());

What do I need to change on format to put *** at the end of my sentence? The way it is now it puts spaces.
