Subtracting Dates [Resolved]

[MethadoneBoy]

Hi everyone,

I'm trying to write a program that regarding dates. Specifically, what I'm trying to do is this : compare two dates to see if one is less than 10 days away from the other.

EG

int days = 10;

if ( thisDate - thenextdate > days ) System.out.println ( "Less that 10 days to go" );
else System.out.println ( "No problems" );

Any help would be appreciated

Thanks

Well, what kind of problems is it generating?

Are you using a Calendar object to get the date or a Data object?

You could create a gregorian calendar object and then calculate the elapsed time.

import java.util.*;
public class ElapsedMillis {
   public static void main(String[] args) {
      GregorianCalendar date1 = new GregorianCalendar(1969, Calendar.JULY, 16, 9, 32);
      GregorianCalendar gc2 = new GregorianCalendar(1995, 11, 1, 3, 2, 2);
      // the above two dates are one second apart
      Date d1 = date1.getTime();
      Date d2 = gc2.getTime();
      long l1 = d1.getTime();
      long l2 = d2.getTime();
      long difference = l2 - l1;
      System.out.println("Elapsed milliseconds: " + difference);
   }
}

I'm not for sure that this will work or that is what you want. I can't test it right now because I'm not at my laptop with the jdk.

Also, I think this checks the difference in milliseconds, so you might have to do some converting or something. But maybe someone else will help you that knows more than me.

No, actually what you have there is exactly what I was looking for.

Thanks!
