       SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");
        sdf.setLenient(false);
        String s = "25:10";
        Date d = null;
        try {
            d = sdf.parse(s);
        } catch (ParseException ex) {
            System.out.println("Invalid Date");
        }

Yeah parse it throught the date format classes and see if it throws an exception. If it throws an exception you know that there is a problem. Also if you do that you can even specify stuff like 12 hour times in stead of 24 hour and stuff like that.

There is also a flag for 1-24 and 0-23 where the latter is the standard depending on your locale settings
