Money Dezimal Number

Code (Java):

String strMoney = "" + money;
strMoney = strMoney.replace(".", ",");

//Just set strMoney to your scoreboard

 

Well... that'd work, but I assume what he wants is to have numbers formatted as they do in Germany. A less hacky approach would be to take the numeric value and use localization:

Code (Text):

DecimalFormat decFormat = (DecimalFormat)DecimalFormat.getNumberInstance(Locale.GERMAN);

whateverMethod() {
  double someNumber = 123456789;
  String display = decFormat.format(someNumber);
}

By asking that, I assume you are not developing your own plugin so ignore what I just said. Hmmm you'd have to check with whatever plugin is providing data to your scoreboard to see if it supports formatting.
