Add One Day to Joda-Time DateTime

Question

I have a date Wed May 08 00:00:00 GMT+06:30 2013 . I add one day to it using Joda-Time DateTime .

 DateTime dateTime = new DateTime(date); dateTime.plusDays(1); 

When I print DateTime, I got this date 2013-05-08T00:00:00.000+06:30 . Jod's date time did not add a single day. I did not find any errors.

thank

Answer 1

The plusDays method plusDays not a mutator. It returns a copy of this DateTime object with the change, not the change, of the given object.

If you want to change the value of the DateTime variable, you need to:

 DateTime dateTime = new DateTime(date); dateTime = dateTime.plusDays(1); 

Answer 2

If you want to add days to the current instance of the date, use MutableDateTime

 MutableDateTime dateTime = new MutableDateTime(date); dateTime.addDays(1);
