Java calendar day_of_week not working
- by Raptrex
I have a for loop starting at startTime going up to endTime and I would like it to print out the date if it is either a monday, tuesday, wednesday, thursday, or friday. Currently, it is only printing out the endTime date. The other stuff splits the string, which you can ignore.
Since 5/16/2010 is a sunday, it should print out 17,18,19,20,21, 24 and 25. However it only prints 25

startCal.setLenient(true);
String[] start = splitString(startTime);
//this sets year, month day
startCal.set(Integer.parseInt(start[2]),Integer.parseInt(start[0])-1,Integer.parseInt(start[1]));
startCal.set(GregorianCalendar.HOUR, Integer.parseInt(start[3]));
startCal.set(GregorianCalendar.MINUTE, Integer.parseInt(start[4]));
if (start[5].equalsIgnoreCase("AM")) { startCal.set(GregorianCalendar.AM_PM, 0); }
else { startCal.set(GregorianCalendar.AM_PM, 1); }
