To subtract days to a JavaScript Date object, use the setDate method. Under that, get the current days and subtract days. JavaScript date setDate method sets the day of the month for a specified date according to local time. You can try to run the following code to subtract 10 days from the current date. I am trying to compare two date values,one date is coming from Created Date field and another date is Variable date which we hard coded. Both field date and Variable date also in same format. Let vCreationDate = date(’2/1/2015’) this is the condition I am trying to compare but not able to get the correct result.posted 17 years agoHello, I am trying to compare the LAST MODIFIED dates of some folders my application is viewing, and I only want to display the folders that were last modified TODAY. Here is what I have so far
-------------------------
<%@ page import=’java.io.*’ %>
<%@ page import=’java.util.*’ %>
<%
File dir = new File(’/DATA/tomcat4/webapps/tf/DICOM’);
//the DICOM folder has a bunch of folders in it
String[] files = dir.list();
for (int i = 0; i < files.length; i++) {
String thepath = dir.getPath();
thepath = thepath + ’/’;
thepath = thepath + files[i];
File f = new File(thepath);
String newpath = f.getPath();
out.print(’<BR>’ + newpath + ’<BR>’);
long lastmod = f.lastModified();
out.print(’Epoch time last modified: ’ + lastmod);
java.util.Date d = new java.util.Date(lastmod);
out.print(’<BR>Date last modified: ’ + d + ’<BR>’);
thepath = ’;
}
%>
----------------------------------------
it ouputs something like this:
/DATA/tomcat4/webapps/tf/DICOM/1689236
Epoch time last modified: 1063043798000
Mon Sep 08 11:56:38 MDT 2003
/DATA/tomcat4/webapps/tf/DICOM/1662170
Epoch time last modified: 1063121523000
Tue Sep 09 09:32:03 MDT 2003
/DATA/tomcat4/webapps/tf/DICOM/1111111
Epoch time last modified: 1062774534000
Fri Sep 05 09:08:54 MDT 2003
-------------------------------------------
But I really only want to show the one in the middle that was last modified today.
Any ideas?Marshalposted 17 years agoHi peter,
Even though you are performing this function in a JSP, it’s still a general Java question, so I’m moving this to Java in General/Intermediate.

[Asking smart questions] [About Bear] [Books by Bear]Ranch Handposted 17 years agoOne way to get a ’Date’ instance that has today’s Date but no time (i.e., midnight) is:
Calendar todayCal = Calendar.getInstance();
todayCal.clear(Calendar.HOUR_OF_DAY);
todayCal.clear(Calendar.HOUR);
todayCal.clear(Calendar.MINUTE);
todayCal.clear(Calendar.SECOND);
Date todayDate = todayCal.getTime();
System.out.println(’TODAY: ’ + todayDate);
You can then do a Date compare:
java.util.Date d = new java.util.Date(lastmod);
if (d.after(todayDate)) {
.. // print the values you want
}
Also, in your code you are using:
String[] files = dir.list();
and then in the loop you are manually building the file path. There is another method you could use to get an array of File instances, rather than just the names:
File[] files = dir.listFiles();
Inside your loop you can use ’files[i]’ as the File instance and can save all the effort of concatenating the directory and creating the File.

Compare Current Date With Another Date In Jsp Form
In the following example we are going to calculate the differences between two dates. First, we will need to convert the date into the corresponding value in milliseconds and then do the math so we can get the difference in days, hours, minutes, etc.Compare Current Date With Another Date In Jsp File
For example to get the difference in day we will need to divide the difference in milliseconds with (24 * 60 * 60 * 1000).
Here is the result: Fossil fighters champions cleaning tips.

The better way to get number of days between two dates is to use the Joda Time API. In the following example you can see how to calculate date difference using Joda Time: How do I get number of days between two dates in Joda Time?.Compare Current Date With Another Date In Jsp Login
