How to validate a date in Java

Hello,
I would like to validate dates entered in an GUI. Is there a simple way to do that in Java ?
Thanks a lot.

But first setLenient(false), because to my mind
DateFormat it apt to be far too lenient
tending to accept things like 30 Feb.A web banking application had setLenient(false). Customers would call support because they got an error message when they tried to get transaction statements for the whole month by entering April 1 - April 31.
We changed to setLenient(true). Consider which leniency mode is right for you. And write better error messages than what we had...
Maybe: if non-lenient fails, parse with lenient; if that succeeds, give a specific error message explaining the situation (or execute with the lenient date, and present results with a warning message "we made a guess at what you meant, check results").

Hi,
I think there is no need to put chain endchain.
To do validation you have to write module in PAI which does required validations.

How to validate a date in message mapping

Hi experts,
how to validate a date in message mapping. For ex: if date comes as 2008/02/31, then file it shold not get processed.how to achieve this in message mapping. Please help .
Thanks&Regards,
Reyaz Hussain

Hi,
There are few simple ways for date validation as follow,
1.If you would like to handle it in XI only, then in message mapping you could verify about it with the help of generating smart exception.
For e.g in mapping there is one Date conversion API i.e. somthing DateTransformation It converts the incoming date format to required format. Here give the date format i.e expected from Sender File.
If in case the format miss-matched then it will create the exception.
You could handle this exception with the use of [Alert notification|http://help.sap.com/saphelp_nw04/helpdata/en/2c/abb2e7ff6311d194c000a0c93033f7/frameset.htm] and could be even able to notify to sender system about it.
2. The another solution is easy for SAP synchornous communication --If you are passing the file data to SAP, then you could use below function modules to verify date format in receiver RFC/BAPI or inbound IDOC program. If the sy-subrc is not 0 then don't process further.
CONVERT_DATE_FORMAT
ISU_DATE_FORMAT_CHECK

Who can tell how to validate a date in poor java?

My programm can let user to input date in the default dateformat. Before save it to database I'd validate if the input is valid date. buf I can't find any function to do it both in java.util.Date and java.sql.Date, my program is as follow:
DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT); // in default Locale
java.util.Date testdate;
input = jtfInDate.getText().trim();
if(!input.equals("")) {
try {
testdate = df.parse(input);
} catch(ParseException pe) {
JOptionPane.showMessageDialog(this,
"<html><font color=red size=4>invalid date format</font></html>",
"warning",
JOptionPane.WARNING_MESSAGE);
return false;
System.out.println("indate" +testdate);
If I input "dafafa" in the jtfInDate(is a JTextField),the DateFormat can detect that's invalid and throw ParseException. But when I input "9999-99-99", the DateFormat can parse it without Exception!!!
and print out as "indate=Thu Jun 07 00:00:00 CST 10007", year 10007!!!!
"9999-99-99" is obviously a invalid date format. Why DateFormat.parse() can think is OK?
Is this the java's excellency????
Could anyone tell me how to judge a string of date is valid?

You can use the setLenient method to tell the DateFormat object to stop trying to help you out, this should go some way toward getting you where you need to go. Check the API docs out for that.
Good Luck
Lee
PS: don't mind esran, he's not the sharpest tool in the shed, and is likely still trying to figure out the mess he documented in this thread:
http://forum.java.sun.com/thread.jsp?thread=519291&forum=31&message=2479820

How to validate when date format is diff Internally and externally

Hello,
How can I validate the Date format if Internal format and external format is different.
Ex :
* SELECT SINGLE CRTSP
**                FROM /SAPSLL/PR
**                INTO L_CRTSP
**                WHERE CRTSP IN S_CRTSP .
CRTSP (YYYY/DD/MM HHMMSEC) Internal Format
S_CRTSP (YYYY/DD/MM) External format - selection option
I had done following to convert the internal format to external format.
DATA : LV_DT TYPE STRING.
DATA : L_CRTSP TYPE /SAPSLL/CRTSP.
SELECT SINGLE CRTSP
                FROM /SAPSLL/PR
                INTO L_CRTSP.
MOVE : L_CRTSP TO LV_DT. "(YYYY/DD/MM HHMMSEC)
L_LEN = STRLEN( LV_DT ).
L_DATE = LV_DT+0(8).
I have the date format that i need in L_DATE." (YYYY/DD/MM)
Now how should I validate?
* SELECT SINGLE CRTSP
**                FROM /SAPSLL/PR
**                INTO L_CRTSP
**                WHERE CRTSP IN S_CRTSP .
Please let me know how can I validate or how can I write the select query to validate this field.
There should be some way using Wildcard or some function module...which I am not sure...
Any suggestions will be appreciated!

Kittu

Hello,
Thank you for youe response and I apprecaite the help so far.
This logic work if it is Parameter...When I have select option it is not working as it is not taking the range values...
SELECT GUID_PR "Primary Key as GUID in "RAW" Format
CRTSP "PRODUCT CREATED ON
CHTSP "PRODUCT CHANGED ON
FROM /SAPSLL/PR
INTO TABLE T_PR.
DATA : T_PR1 TYPE TY_PR OCCURS 0 WITH HEADER LINE.
DATA: W_TEST    TYPE STRING,
       W_LV_LEN TYPE I,
       W_LV_LEN1 TYPE I,
       W_LV_DATE(20) TYPE C,
       W_LV_DATE1(20) TYPE C.
DATA : W_V(8) TYPE C,
       S_CT(11) TYPE C.
SORT T_PR BY CRTSP CHTSP.
LOOP AT T_PR INTO WA_PR.
W_TEST = WA_PR-CRTSP.
W_LV_LEN = STRLEN( W_TEST ).
W_LV_DATE = W_TEST+0(8).
** IF WE SELECT ONLY ONE DATE IN SELECT OPTION
s_crtsp VALUE IS - IEQ20040101..bY REMOVING FIRST THRID DIGITS
WE ARE GETTING THE S_CRTSP VALUE IS 20040101 AND THIS LOGIC IS WORKING FINE..
   MOVE S_CRTSP TO S_CT.
W_LV_LEN1 = STRLEN( S_CT ).
W_LV_DATE1 = S_CT+3(8).
* IF W_LV_DATE NE S_CRTSP
IF W_LV_DATE NE W_LV_DATE1.
W_FLG = 'X'.
    DELETE T_PR INDEX SY-TABIX.
ENDIF.
CLEAR W_FLG.
ENDLOOP.
Can we do anything for this...
ANy suggestions would be apprecaited!

Kittu

How to validate the date in my class

Hi

So in the action class I want to validate the date that is the date is in dd/mm/year format?
can anybody please give some idea to do this?
Thank you so much.

Here is a method that validates day/month/year using the Calendar class.
     public boolean validateDate(int day, int month, int year) {
          try {
               Calendar cal = Calendar.getInstance();
               cal.clear();
               cal.setLenient(false);
               cal.set(year, month-1, day);
               // need to call getTime() to make the calendar compute/validate the date
               cal.getTime();
               return true;

[b]java.util.Date utilDate = new java.util.Date(delDate);

How to validate the data in the table

Hi Experts,
My question is
I am having a table control on my view. I need to validate the data entered by the user on the table
and after validation i need to save the data into database table.
Now my question is only related to Data Validation on table UI element.
If the user enters 3 rows and if the 2nd and 3rd row are already existing,
It should throw the message Entry already exists and the pointer should
be at Row number 2 in this case.
Similarly in the 2nd row i have a date field and if the user enters some character
then it should throw an error message that Numeric values are only allowed and
the pointer is placed in the 2nd row Date column so that it allows user to modify
the wrong entry.
Please advise.
Regards,
Chitrasen

Hi,
for validating user input in table , you have to get the entries inserted by user into an internal table using get_static_attribute_table and futher have your check using loop endloop.
For date field, make the context attribute binded to date column as DATS. This would make sure the user inputs a valid date without your custom code.

How to validate a date field

actually i am getting a date string from the user.i want compare with the previousdate and i have to display a alert if the entered date is previous date.pls give me some example coding for this process

Hi, i had tried in the way you suggested but couldn't get it right. Also i dont want much complexity to be added to this validation purpose.So i just want to do it in the java script and i think there will be no problems with the browser settings.
What i need is i just want to validate whether the date entered into that textbox is in yyyy-mm-dd format. Also in the mysql database i am using the date will be entered in the yyyy-mm-dd format and i saw somewhere in the forum that while validating in javascript it is not possible to give in yyyy-mm-dd format i.e., it doesnot identify the hyphen and only slash needs to be given. So what should i do for this validation to be perfect.This should be simple with little complexity and accurate.Can anyone give me the suggestion regarding it. or if possible the sample code.I need it very urgent.

How to validate a date item "DD/MM/YYYY HH24:MI" ?

Hi,
I want to create a validation item. I have a date item usinhg this mask : "DD/MM/YYYY HH24:MI".
I want to validate if a date entered according to this syntax "DD/MM/YYYY HH24:MI"
Unfortunately APEX gives me only the choice to validate if a date is under the form "DD/MM/YYYY" which gives this syntax :
^([012]?[[:digit:]]|3[01])/(0?[[:digit:]]|1[012])/[[:digit:]]{4}$I don't know this syntax, do you know how I could transform it (I mean adding the hours and minutes criteria) to attain my goal ?
Sorry for my english, not perfect, today !
Regards,
Christian

Try this:
SELECT REGEXP_INSTR('04-OCT-2011 23:12',
'^([012]?[[:digit:]]|3[01])-(JAN|FEB|MAR|APR|MAY|JUN|JUL|AUG|SEP|OCT|NOV|DEC)-[[:digit:]]{4}[[:space:]][0-2][0-9]:[0-9][0-6]$') test_result
FROM dualFor case-insenstive matching, use below:
SELECT REGEXP_INSTR('04-OCT-2011 23:12',
'^([012]?[[:digit:]]|3[01])-(JAN|FEB|MAR|APR|MAY|JUN|JUL|AUG|SEP|OCT|NOV|DEC)-[[:digit:]]{4}[[:space:]][0-2][0-9]:[0-9][0-6]$',1,1,0,'i') test_result
FROM dualThanks!
