ønsker er løbe igennem et år (2005) og udskrive en linie pr dag

import java.util.*;

public class TheYear {
    public static void main(String[] args) {
        HashMap timer = new HashMap();
        timer.put(new Integer(Calendar.MONDAY), new Double(7.5));
        timer.put(new Integer(Calendar.TUESDAY), new Double(6.0));
        timer.put(new Integer(Calendar.WEDNESDAY), new Double(6.0));
        timer.put(new Integer(Calendar.THURSDAY), new Double(6.0));
        timer.put(new Integer(Calendar.FRIDAY), new Double(5.0));
        timer.put(new Integer(Calendar.SATURDAY), new Double(3.0));
        timer.put(new Integer(Calendar.SUNDAY), new Double(6.5));
        process("2005", timer);
    }
    public static void process(String year, HashMap timer) {
        int y = Integer.parseInt(year);
        Calendar cal = new GregorianCalendar();
        cal.set(Calendar.YEAR, y);
        cal.set(Calendar.MONTH, Calendar.JANUARY);
        cal.set(Calendar.DAY_OF_MONTH, 1);
        while(cal.get(Calendar.YEAR) == y) {
            System.out.println(cal.getTime() + " = " + timer.get(new Integer(cal.get(Calendar.DAY_OF_WEEK))));
            cal.add(Calendar.DAY_OF_MONTH, 1);
        }
    }
}

undskyld mit sene svar

perfekt 

hvordan laver jeg cal.getTime() om til f.eks. "19-10-2004 00:00:00"

Prøv:

DateFormat df = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
String s = df.format(cal.getTime());
