How to get date of next anniversary ?

[Sylvia Wang]

Hi, all
is there any easy way( no complex conversion) to get a new Date of the next anniversary of a given Date ?
e.g. from 12/13/2001 => 12/13/2002
Thanks.

java.util.Date today = new java.util.Date();
Calendar anniversary = Calendar.getInstance();
anniversary.setTime(today);
anniversary.add(Calendar.YEAR, 1);
//convert back if necessary
java.util.Date today_plus1year =  anniversary.getTime();

Thank you !

Sorry, found a small problem,
the Date type returned by getTime() is java.util.Date
tried to downcast to java.sql.Date by
java.sql.Date = (java.sql.Date)util_date;
but doesn't work. why ?
Thxs.

Try this...
java.util.Date today = new java.util.Date();
java.sql.Date td = new java.sql.Date(today.getTime());

here is a neat and quick way to convert it in your code:

Calendar anniversary = Calendar.getInstance();
anniversary.setTime(new java.util.Date());
anniversary.add(Calendar.YEAR, 1);
//convert back if necessary
[B]java.sql.Date today_plus1year =  new java.sql.Date(anniversary.getTime().getTime());[/B]

the first getTime() returns a Date object, the second getTime() is on the returned Date object which returns a long...which is used in the constructor of java.sql.Date.
