Question

I am using “MM/dd/yyyy hh:mm a” to initialize SimpleDateFormat.setLenient option is set false.
Below are some use cases

1)input String:-01/02/2001 3:09 AM
expected:-should pass
actual:-passes

2)input String:-01/02/20016 3:09 AM
expected:-should NOT pass
actual:-passes
I don’t understand why 20016 is parsed as valid one!!!!!

I agree with Peter and mprivat, but if you really need to do this a solution could be:

    DateFormat df = new SimpleDateFormat("MM/dd/yyyy hh:mm a") {
        public synchronized Date parse(String source) throws ParseException {
            Calendar cal = Calendar.getInstance();
            Date d = super.parse(source);
            cal.setTime(d);
            if (cal.get(Calendar.YEAR) > 9999 ) {
                throw new ParseException("Year too long", 11);
            }
            return d;
        };
    };
