Validating Data in Java

[Ucchal]

Hello,
I have three data, DD the day, month MM YYYY year, and I want to test the logic that date. But I used the methods of Java DateFormat GregorianCalendar, but they only allow to test the format of the date, and though I respect for a data I can assign them values without any errors. Do you have any other alternative than this? Thank you.

This is a very simple code and I think this will help you

public void main (String args []) ( 
CalTester CalTester tst = new (); 

ytt int = 2001; 
mtt int = 10; 
dtt int = 18; 
tst.testDate (ytt, mtt, dtt); 

ytt = 2001; 
mtt = 14; 
dtt = 18; 
tst.testDate (ytt, mtt, dtt); 

ytt = -2001; 
mtt = 7; 
dtt = 21; 
tst.testDate (ytt, mtt, dtt); 

ytt = 2001; 
mtt = 158; 
dtt = 21; 
tst.testDate (ytt, mtt, dtt);

Here is another code which may help you

try 
( 
dtgeocal = new GregorianCalendar (year, nm - 1 day) / / 0 = January 

dtgeocal.setLenient boundary (false) / / without this line, no possible exception 

an dtgeocal.get int = (GregorianCalendar.YEAR); 
nmb dtgeocal.get int = (GregorianCalendar.MONTH); 
jrb dtgeocal.get int = (GregorianCalendar.DAY_OF_MONTH); 
) 
catch (Exception e) 
( 
e.printStackTrace (); 
)

I want to get a date with a JTextField and save it in a MySQL database. I can add but the date is October 15, 1580, even if I put another date. for example code for this date is October 15, 1580, (c d2 and if I record in my database). How am I to insert a date of birth for any customer?

But when you say that you want to record in your database is to be recovered in a JTextField. What form is coming then? What format do you want to send? You have to have a way to send it to your base without or by date or by non Calendar, by doing a get of JTextField, and placing it in the desired shape before the transfer.

To enter a date specific (date of birth mentioned in your example, February 13, 1987):
use it as
Calendar c = new GregorianCalendar (int year, int month -1, int day);
either:
Calendar c = new GregorianCalendar (1987, 1, 13);
