DateDiff() quick question

[Brita]

You guys have been life savers for me, and I appreciate your help so much.

I am trying to check the difference in days between two submitted requests.

DateFormat df = DateFormat.getDateInstance(DateFormat.MEDIUM);
Date firstDate = df.parse(firstRequest);
Date secondDate = df.parse(secondRequest);
int requestDays = DateDiff(dd, firstDate, secondDate);

I get an error that dd can not be resolved.
I tried "DD" and got DateDiff(String , Date, Date) is undefined
I tried Calendar.DATE and got DateDiff(int, Date, Date) is undefined

What do I need to add to make this work?

Thanks again for all your help.

Use the GregorianCalend ar. It has methods that can do what you want. Just open the API specs for it and see.

Thanks! I used the GregorianCalend ar like you suggested and it works just fine.

I still am a little confused by DataDiff() though. Is this a standard Java Function? If not why do I keep seeing it everywhere?

Thanks again.

Tell you the truth I've just started to see it now in your code.
One thing is certain. It's not a standard Java function.
It's probably a method someone wrote in some Date utils class of theirs.

You are probably (certainly) correct.

Thanks again for your help. This is such a great resource. Hopefully, one day I will know enough to help others here.
