Get Dates between the given dates.

Hi, i am trying to do someting like this:

A user choose a initial and a final date. For example:

Ini: 07/07/2004 Fin: 11/07/2004

Ok, what i need to do, is to get all dates between this two above. The answer needs to be...

08/07/2004 09/07/2004 10/07/2004

Is there a method that do this for me, i ve looking for but not finding ?

Thanks...

There is no method, but it should be easy enough. Have a look at the Calendar class and in particular its add(int field, int amount)
method.

Also to convert the string "07/07/2004" into a java.util.Date object (or the reverse) have a look at the java.text.SimpleDateFormat class.

Regards

Try this: one of the simpler ways -

public class DateRangePrinter {
public static void main(String[] args) throws Exception {
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
sdf.setLenient(false);
 
try {
Date startDate = sdf.parse("29/05/2006");
Date endDate = sdf.parse("30/06/2006");
 
List dateRange = getDatesInRange(startDate, endDate, true);
printDateRange(dateRange);
 
} catch (ParseException e) {
e.printStackTrace();
}
 
}
 
/**
 * @param dateRange
 */
private static void printDateRange(List dateRange) {
for (Iterator iter = dateRange.iterator(); iter.hasNext(); )  {
Date date = (Date) iter.next();
System.out.println("DATE --> " + date);
}
}
 
/**
 * @param startDate
 * @param endDate
 * @param b
 */
private static List getDatesInRange(
Date startDate,
Date endDate,
boolean includeStartDate)
throws Exception {
 
if (!endDate.after(startDate)) {
throw new Exception("INVALID DATE RANGE: end date should be after start date");
}
 
final long ONE_DAY = 24 * 60 * 60 * 1000;
long startTime = startDate.getTime();
long endTime = endDate.getTime();
 
List dateRange = new ArrayList();
 
if (includeStartDate) {
dateRange.add(startDate);
}
 
for (long currentTime = startTime;
currentTime < endTime;
currentTime++) {
currentTime += ONE_DAY;
Date date = new Date(currentTime);
dateRange.add(date);
}
 
return dateRange;
}
}

Check the time component of dates that your have generated if that is used in your application.

If your date range has has dates when daylight saving is turned on or off then time component changes while you increment date using calendar API, e.g 24:00 in your code may change to 23:00 or 01:00.

hi,

i had almost the same problem and solved it quite comfortably with the joda-time framework. just google for it, it's a sourceforge project. these guys did a great job, specially when it comes to daylight saving time and leap-years...

hope it helps,

greetings from world-cup crazy berlin,
