NumberFormateException

Hai folks,

Actually,in my application  Im getting the value of DOB from the user using 
a DateField class called dob and storing it in DB(RMS).Its working fine.

Now i want to display the same DOB value retrieved from the DB to another 
DateField class called dob1.
I tried with the following code.But its throwing NumberFormateException.

Assume that ,The 'dob' value retrived frm the DB is now assigned to  some 
character array called arr[].that is,

                     dob=arr[j];
                     dob1.setDate(new Date(Integer.parseInt(arr[j])));

How to modify this code to resolve the exception.
