Now i use this:

1. int fatilityCountDay = getCount(getFatalitiesAtDay(iDate));

But i prefer to switch my function to use it like this:

1. getFatalitiesAtDay(iDate).getCount();

How can i do that?
Here are my functions that i made now:

sorry for bad alignment, don't know why it doesn't copy paste it correct

1. public ArrayList<Fatality> getFatalitiesAtDay(DateTime AtDay) {
2. ArrayList<Fatality> results = new ArrayList<Fatality>();
3. for( Fatality f : fatalities) {
4. if(Days.daysBetween(f.date, AtDay).getDays() == 0) {
5. results.add(f);
6. }
7. }
8. return results;
9. }
10. // - - - - - - - - - - - - - - - - - - - - - - - - - - -
11. public int getCount(ArrayList<Fatality> fatalities) {
12. return fatalities.size();
13. }
