how to get a list of dates between two dates in java

Question

I want a list of dates between start date and end date.

The result should be a list of all dates including the start and end date.

Answer 1

Back in 2010, I suggested to use Joda-Time for that.

Note that Joda-Time is now in maintenance mode. Since 1.8 (2014), you should use java.time.

Add one day at a time until reaching the end date:

int days = Days.daysBetween(startDate, endDate).getDays(); List<LocalDate> dates = new ArrayList<LocalDate>(days);  // Set initial capacity to `days`. for (int i=0; i < days; i++) {     LocalDate d = startDate.withFieldAdded(DurationFieldType.days(), i);     dates.add(d); } 

It wouldn't be too hard to implement your own iterator to do this as well, that would be even nicer.

Answer 2

java.time Package

If you are using Java 8, there is a much cleaner approach. The new java.time package in Java 8 incorporates the features of the Joda-Time API.

Your requirement can be solved using the below code:

String s = "2014-05-01"; String e = "2014-05-10"; LocalDate start = LocalDate.parse(s); LocalDate end = LocalDate.parse(e); List<LocalDate> totalDates = new ArrayList<>(); while (!start.isAfter(end)) {     totalDates.add(start);     start = start.plusDays(1); }
