# of Days between dates

[tmryan]

Kind of new to Java - pardon the newbie question.
I've created a form that has a couple of input fields and a button. The goal is to prompt for two dates and display the number of days between the two. I've been playing around with java.util.Date - but haven't figured it out yet. In the DB language I primarily use - dates are stored as the number of days since 01/01/1900. Is there a similar way to do this in Java?

Thanks Tim Ryan

I think you need to switch over to javascript which can help you doing the form validations and other issues

Yes there is. In the class java.util.Date, there is this method getTime() that returns the number of milliseconds since January1 as a long type.

You can get the long value of the 2 date and subtract them and convert the difference from milliseconds to day.
