Re: Subtracting a day from java.sql.Date

Hey Kenny,

FYI...

      // Establish a Date object
      Date d = new Date();

      // Establish a Calendar object
      Calendar cal = Calendar.getInstance();

      // Set the Calendar object to your date
      cal.setTime(d);

      // Subtracts 5 days from the date
      cal.add(Calendar.DATE, -5);

      // Increments the date by one
      cal.roll(Calendar.DATE, true);

      // Decrements the date by one
      cal.roll(Calendar.DATE, false);

      // Convert the Calendar object back to a Date
      Date newDate = new Date(cal.getTime().getTime());


Hope this helps.

Best Regards,

Mike

Subject: Subtracting a day from java.sql.Date

Hello all.  I'm trying to subtract a day from a java.sql.Date class
variable.  Looking at the java docs, there is no method to do this.  All
the
date modification methods belong to another class, java.util.Calendar.
To
be able subtract a day from my class, should I convert it to the
Calendar
class and then back to the Date class or is there something easier that
I'm
missing.  My main requirement is to have it in a java.sql.Date class
when
done.  Any example code would be much appreciated (I have to admit I'm
still
a lightweight in Java).

Thanks,
Kenny
