Gregorian calendar multiple dates

[tirwit]

Is it possible to create a GregorianCalendar object and set multiple dates in it? For creating intervals of time in it, and then associate it with a person.

This is to be used to create a vacation calendar so multiple intervals.

If you have any good idea or other approach to the problem, please share!:o

No, a Calendar works on one moment in time only; that moment in time may change though; you can get/set it with the get/setTime() methods. If you want to manage more than one moment in time use the Date(s) returned by the getTime() method.

Ok, I wrote some code, but I'm having trouble with calculating work days between 2 days.

This is it:

public static int daysBetween(GregorianCalendar startDate, GregorianCalendar endDate) {  
	  GregorianCalendar date = (GregorianCalendar) startDate.clone();  
	  int daysBetween = 0;  
	  while (date.before(endDate)) {  
		date.add(GregorianCalendar.DAY_OF_MONTH, 1);
		
		if(date.equals(GregorianCalendar.SATURDAY) || date.equals(GregorianCalendar.SUNDAY)){}
		
		else
		daysBetween++;
	  }  
	  return daysBetween;  
	}

But GregorianCalendar.SATURDAY is of type int... How can I compare date to a GregorianCalendar object to see if it a saturday?

date.get(Calendar.DAY_OF_WEEK)? It's all in the API documentation you know ...

kind regards,

I tried that before but it was not working. I had imported only the GregorianCalendar, because I thought that since GregorianCalendar is a extension of Calendar, all the methods would be there as well. Turns out I was wrong. I imported the Calendar and now it's working! Thank you so much.

PS: I was not slacking, I read the the API, but I have 3 days of Java, so I'm still learning to move around here (the "extend" stuff and such) :-) Thanks for your time showing me how to!
