[RESOLVED] Calendar week view

I want to create a week view but I can't figure out how to get the first date of this week (03/01/2010) and the last date (09/01/2010). I found this script but I get as first date 10/01/2010 and as last date 09/01/2010 and I don't see why I get 10/01/2010 as first date.

Code:

---

// Code to test it.
GregorianCalendar calendar = new GregorianCalendar();
               
                //Get the interval
                String [] interval = calendarModel.getWeekInterval(calendar);
 
                System.out.println("First day of week: " + interval[0]);
                System.out.println("Last day of week: " + interval[1]);

private DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
    public String[] getWeekInterval(Calendar cal)
    {
        // find start of week

        Calendar start = Calendar.getInstance();
        start.setTime(cal.getTime());
        start.set(Calendar.DAY_OF_WEEK, cal.getActualMinimum(Calendar.DAY_OF_WEEK));

        // find end of week

        Calendar end = Calendar.getInstance();
        end.setTime(cal.getTime());
        end.set(Calendar.DAY_OF_WEEK, cal.getActualMaximum(Calendar.DAY_OF_WEEK));

        // format start and end date and return

        return new String[] { df.format(start.getTime()), df.format(end.getTime()) };
  }
       
        private Calendar getFirstDayOfThisWeek(GregorianCalendar cal)
        {
                cal.add(Calendar.DAY_OF_YEAR, Calendar.SATURDAY);
 
                return cal;
        }
       
        private Calendar getLastDayOfThisWeek(GregorianCalendar cal)
        {
                cal.add(Calendar.DAY_OF_YEAR, Calendar.SATURDAY);
 
                return cal;
        }

Pay attention to what you are reading and displaying. Using today's date arbitrarily you get:

01/03/2010 and 01/09/2010

as the boundaries.

I should mention now that

Code:

---

        private Calendar getFirstDayOfThisWeek(GregorianCalendar cal)
        {
                cal.add(Calendar.DAY_OF_YEAR, Calendar.SATURDAY);
 
                return cal;
        }
       
        private Calendar getLastDayOfThisWeek(GregorianCalendar cal)
        {
                cal.add(Calendar.DAY_OF_YEAR, Calendar.SATURDAY);
 
                return cal;
        }

---

are both the same method, they do the same thing, and you should realize that you are adding to the current date object a year modifier, with the constant Calendar.SATURDAY which is equal to 7.

Didn't think to post this the first time around, but if you want a full understanding of date and time as it relates to Java and the various wrapper classes it provides, this is a very informative and a good read for you, or anyone for that matter to go over:

Thank you, that link helped me a lot. I fixed it now
