Thread: Calendar class is giving me problems!

I'm trying to generate a list of date between date1 and date2, without success.
What am i doing wrong? Here's my code:
-----------------------------------------------------------------------------

private static void dateRange()
     {
         Calendar c1 = new GregorianCalendar();
         c1.set(2011,01,01);
         Calendar c2 = new GregorianCalendar();
         c2.set(2011,12,31);
 
         while(!c1.equals(c2))
         {
            SimpleDateFormat sdf = new SimpleDateFormat("MMyyyy");
            String date = sdf.format(c1.getTime());
            System.out.println(date);  
            c1.add(Calendar.DATE,1);
         }
     }
