is it normal behaviour of SImpleDateFormat?

[aminur rashid]

Here is the code.

SimpleDateFormat tempF = new SimpleDateFormat("MM/dd/yyyy");
tempF.setLenient(false);
JFormattedTextField tempt = new javax.swing.JFormattedTextField(tempF);

Now if i creat SimpleDateFormat with the string MM/dd/yy the behaviour of JtextField is normal.
By normal i mean it accepts date as 11/11/11 only and not 11/11/11111111
But if i create SimpleDateFormate with String MM/dd/yyyy
the formattted textfield can accept year upto 9 digit.
i mean i can enter date as
02/03/12345678
Howver i was expecting that user can only enter
02/03/1234 [after validation]
but he can enter value
02/03/12345678
??
any idea??
the validation for MM/dd/yy is working fine.
here is the test code

 
import java.text.SimpleDateFormat;
import java.text.ParseException;

public class SimpleDateFormatterTest 
{
public static void main(String args[])
{
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
SimpleDateFormat sdf1 = new SimpleDateFormat("dd/MM/yy");

sdf.setLenient(false);
String dateStr = "12/03/123456789";
try
{
System.out.println("Date after format : dd/MM/yyyy"+sdf.format(sdf.parse(dateStr)));//itdont
System.out.println("Date after format dd/MM/yy : "+sdf1.format(sdf1.parse(dateStr)));//it behaves normally
} 
catch (ParseException e)
{
e.printStackTrace();
}
}

}

That is normal behaviour for the SimpleDateFormat. Anytime you have four characters together, it will accept (as literal), the value entered. Thus:
MM/dd/yyyy
will accept:
03/10/1980 - 10 March 1980 CE
04/01/34908 - April Fool's Day, 34908 CE
11/11/11 - 11 November, 11 CE (When Caesar Augustus was emperor of Rome)
If you want to limit the number of digits in the year, you will have to implement some other validation routine.

Seems to work just fine to me. The world doesn't come to an end in 9999 (If it does, we'll never see it)
If you wish to restrict the users input closer, you'll need to write your own method.
