Date diff function in java

[saahil sinha]

Hi guys,
I like to know if there is any function in java that will perform the diffrence between 2 dates and return it in the no. of days between the 2 dates.If yes what is the function and its syntax

You mean something like this:

import java.util.*;
public class DaysBetweenDates {
    public static final long DAY = 24 * 3600 * 1000;
    
    public static int daysBetweenDates(Date d1, Date d2) {
        int days = (int) ((d1.getTime() - d2.getTime()) / DAY);
        return Math.abs(days);
    }
}

Hi,
Ur code did give me some idea so i did some thinkin and this is what i actually coded and wanted.
import java.util.*;
public class test_time
{ public static final long DAY = 24 * 3600 * 1000;
public static void main(String args[])
{
GregorianCalendar gcl1=new GregorianCalendar(2002,2,29);//entry date
GregorianCalendar gcl2=new GregorianCalendar();//return date
daysBetweenDates(gcl1,gcl2);
}
public static void daysBetweenDates(GregorianCalendar d1,GregorianCalendar d2)
{
Date day1=d1.getTime();
long dd1=day1.getTime();
Date day2=d2.getTime();
long dd2= day2.getTime();
int de=(int)((dd1-dd2)/DAY);
System.out.println(day1+":"+day2+"::"+de);
}
}
Anyways thanx a lot
