get date object in java from a date string

Question

I have a jquery datepicker on my page :

$( "#dob" ).datepicker({
        yearRange: "-100:+0", 
        dateFormat: 'dd-mm-yyyy',
        changeMonth: true,
        changeYear: true,
        showAnim: 'slideDown',
        minDate: '-100Y',
        maxDate: '-1D'
    });

I am getting dob string as : 25-12-1988 in my servlet.

i tried this :

SimpleDateFormat formatter=new SimpleDateFormat("dd-mm-yyyy");
            try {
                ud.setDob(formatter.parse(dob));
            } catch (ParseException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

to insert this in Db i am doing this :

pstm.setDate(9,new java.sql.Date(ud.getDob().getTime()));

and in db i got this : 1988-01-25 00:00:00 which is incorrect.

datatype of column is datetime

where is the problem ?

mm is "minutes". "Months" is MM:

SimpleDateFormat formatter=new SimpleDateFormat("dd-MM-yyyy");

(See the javadoc for java.text.SimpleDateFormat.)

Um, are you going to provide the fixed format instead of just the broken one?

can i make sure before parsing that the string is in correct format---- for example if i would get string like this : 25/12/1988 or 25-12-88 then it will through an exception ??

@JAVAGeek: For 25/12/1988, you don't need to do anything special; it will automatically raise an exception. 25-12-88 is trickier, because as far as SimpleDateFormat is concerned, 88 is a valid year. You can either use a regular expression to ensure that it matches \d\d-\d\d-\d\d\d\d (e.g. if(! Pattern.matches("\\d\\d-\\d\\d-\\d\\d\\d\\d", dob)) { throw new Exception(); }), or else check afterward to make sure that the date is within a sensible range. You'll probably also want to call formatter.setLenient(false) so that it's stricter about getting a date that actually exists.
