[Urgent] Need help calculating difference between two dates

I'm trying to write a code to display the current day and time, then accept two dates from the user and display the difference between the two dates. To display the current date and time, I've used the SimpleDateFormatter library but I'm having difficulty calculating the difference between two dates. Could someone please help me with this?
Below is my code so far
import java.util.Date;
import java.util.Scanner;
import java.text.SimpleDateFormat;
public class DateFormatter {
     public void displayNow()
          Date todaysDate = new Date();
          SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MMM-dd HH:mm:ss");
          String formattedDate = formatter.format(todaysDate);
          System.out.println("Today's date and time is: "+formattedDate);
     public void calculateDifference(Date startDate, Date endDate)
          /* This is whre i need help! */
     public static void main(String[] args)
          DateFormatter df = new DateFormatter();
          Scanner sc = new Scanner(System.in);
          df.displayNow();
          System.out.println("Please enter a date: ");
          String date1 = sc.next();
          System.out.println("Please enter another date: ");
          String date2 = sc.next();
}The methods displayNow() and calculateDifference(Date startDate, Date endDate) are essential and cannot be skipped out.

Dude. I've tried doing assignments under pressure, and it doesn't work. Here's a piece of free advice. Start earlier next time, don't put "urgent" in the title of your post b/c it just pisses people off around here--and is a sure sign of an overdue homework assignment which no one around here likes helping with, and try to ask intelligent questions--don't just say "Help me!"
Of course, it takes some time to learn what the intelligent questions are. You have my sympathy. Try asking questions about how to do a particular task, instead of asking people to tell you what to do. It starts to get easier after a while.
actually dude i started on this on monday.. but there were so many other stuff to do along with this.. and i did try referring up the Calendar utility but it was a bit confusing actually.. it was only after that did i come to this forum.. nor am i very good at Java.. anyhoo thanks for your sympathies :P

  • Calculating difference between two dates in Variable Exits

    Hi,
          I need to calculate the difference between the two dates in months in Variable exits. I want the result in months so that I need to find out the Average Usage.
            How can I find the difference between them in months.
    Thanks

    Hi Christophe, Senthil
                                       Sorry for late response, I checked this  MONTHS_BETWEEN_TWO_DATES_NEW  in SE37/SE38 and about the date they are going to enter at query run time it should be like 03/03/2006 to 08/03/2006 and I should get in 5 months and or if the date range 03/15/2006 to 08/03/2006 and I should get like 4.5 months. Please could you tell me how to get the values in months or please give me a functional module so that I can use.

  • Difference between two date in bex query

    Thanks a lot

    Hi,
    You can still use the same code to copy it and customize as per your need. All you need to do is to subract the dates using the class: CL_ABAP_TSTMP after converting to timestamp and resulting seconds you convert back to days....Please get help from the developers to do this...
    Also, ensure that you write back this difference value to your variable so you get it on the reports for your calculations...

    Hi
    I have two date fields in the ODS..Both are characterists

    You have to make Expiration data as nav attribute and create a formula variable then only this date can be used in calculations.
    refer this How to...for the same

  • Calculate the Difference Between two dates excluding weekends and Holidays

    Hi,
    We need to calculate the difference between the two dates by excluding the Local public holidays (It is global and varies across countries) and weekends should not be included in calculation for a business day in OBIEE.
    We have two dates: Open date and close date when ever close date is null we are calculating age based on taking the current timestamp and need to exclude the weekends and Holidays when ever the close date is null.
    Ex:
    Col1 col2 Total
    11/9/2010 2:46:38 PM Null 13
    11/2/2010 8:06:26 PM 11/3/2010 5:37:03 PM 1
    (In the Total we shouldn't include the weekends,holidays)
    Please let me know how to calculate the difference between two dates by excluding the weekends and holidays.
    Thanks

  • To find difference between two dates

    Hi all,
    I am new to this forum and oracle.
    I want to get the difference between two dates. My query is as below...
    sqlserver_utilities.datediff('YY', startdate,enddate)
    I want the difference in year.
    Please help me. It's really urgent.
    Thanks in advance.
    Regards,
    Inam

    Select to_char(enddate,'YY') - to_char(startdate,'YY') fromPLEASE don't do that. There are so many things wrong with it...
    for example:
    1). Why are you subtracting character data types?
    2). What if the start date is 1999 and the end date is 2000? Do you expect to get a difference of -1?
    3). What if the start date is 1 Jan 2000 and the end date is 31 Dec 2000? Do you expect to get 0 instead of 1 or .997?
    4). Why would you convert dates to something else when they are inherently subtractable.
    5). There are obvious points in the OP's "specification" that are vague - the best thing (after telling them to search, of course since this has been answered a million times already) would be to try to clarify the spec.

  • Difference between two dates into server behaviors

    Good morning all,
    I'm trying to create a recordset using server behaviors and as I'm not an expert using php I'm completely lost...
    The problem is the following : I want to find into a table all the records where the difference between today date and their creation date (stored in that table of course) is greater than, let's say 30days. How can I indicate that into the variables field ?
    Many thanks in advance for your help !

    Many thanks !
    I was ignoring the DATE_SUB function and it does work in such a simple way… (with a closing parenthesis at the end)
    Thanks again !

    I have tried various FMs they all are giving difference in days and hours but I want to know difference in seconds also.
    Thanks in advance.

    Edited by: Thomas Zloch on Mar 11, 2011 10:47 AM

    Michael,
    For VB.net the date difference method is the same as it is for VBA. Depending on whether you want working days or calendar days, the methods are:
    Difference in working days:
    Application.DateDifference(StartDate, FinishDate, Calendar)
    Difference in calendar days:
    DateDiff(interval, date1, date2[, firstdayofweek[, firstweekofyear]])
    You can also use these same formula in a custom field in Project.
    Hope this helps.

    Thanks

    You can always create your own difference function based on your own criteria. You can modify this to suit your needs.
    CREATE OR REPLACE FUNCTION CALC_OFFICE_DAYS(date1 DATE, date2 DATE)
    RETURN NUMBER
    IS
    v_begin_date DATE := date1;
    v_end_date DATE := date2;
    v_office_start_time VARCHAR2(10) := '09:30 AM';
    v_office_end_time VARCHAR2(10) := '06:30 PM';
    v_comp_begin_time DATE;
    v_comp_end_time DATE;
    v_days PLS_INTEGER := 0;
    v_hrs NUMBER := 0;
    v_ttltm NUMBER;
    BEGIN
    select trunc(v_end_date) - trunc(v_begin_date)
    into v_days
    from dual;
    select to_date(to_char(sysdate,'DD-MM-YYYY')||' '||to_char(v_begin_date,'HH24:MI'),'DD-MM-YYYY HH24:MI')
    into v_comp_begin_time
    from dual;
    select to_date(to_char(sysdate,'DD-MM-YYYY')||' '||to_char(v_end_date,'HH24:MI'),'DD-MM-YYYY HH24:MI')
    into v_comp_end_time
    from dual;
    select (v_comp_end_time - v_comp_begin_time)/24 into v_hrs from dual;
    IF v_hrs > 4 then
    v_ttltm := v_days + .5;
    ELSE
    v_ttltm := v_days;
    END IF;
    return v_ttltm;
    END;
    As has been noted, this question is best posted on the PL/SQL forum.

  • As to the data type of the data type of the difference between two date type of datas

    Hi,
    I have a question about the data type of the difference between two date type of datas.
    There are two date type of datas as:
    SSHIPMENTS.RECEIVEDATETIME
    SSHIPMENTS.PROMISEDATETIME
    I try to use the following SQL Script in Oracle SQL*Plus as:
    SELECT CASE
    WHEN (SSHIPMENTS.RECEIVEDATETIME - SSHIPMENTS.PROMISEDATETIME) < '000 01:00:00.000' THEN 'OnTime'
    WHEN (SSHIPMENTS.RECEIVEDATETIME - SSHIPMENTS.PROMISEDATETIME) < '000 01:30:00.000' THEN '60-89 Minutes'
    ELSE '3+ Hours'
    END
    FROM SSHIPMENTS;
    The error message of "Invalid Number" for the '000 01:30:00.000' happens.
    I don't know if the data type of the interval is wrong.
    Many Thanks,
    Cathy

    SELECT CASE
    WHEN (to_char(SSHIPMENTS.RECEIVEDATETIME,'hhmiss') - to_char(SSHIPMENTS.PROMISEDATETIME,'hh24miss')) < '010000' THEN 'OnTime'

    To break the diff between 2 dates into days, hours, minutes, sec -- you can use the following:
    select to_char( created, 'dd-mon-yyyy hh24:mi:ss' ),
    trunc( sysdate-created ) "Dy",
    trunc( mod( (sysdate-created)*24, 24 ) ) "Hr",
