        try {
            // Declare a date format for parsing
            SimpleDateFormat dateParser = new SimpleDateFormat("h:mm a");

            // Parse the time string
            Date date = dateParser.parse("3:30 PM");

            // Declare a date format for printing
            SimpleDateFormat dateFormater = new SimpleDateFormat("HH:mm");

            // Print the previously parsed time
            System.out.println(dateFormater.format(date));

        } catch (ParseException e) {
            System.err.println("Cannot parse this time string !");
        }
    }
}

Console output is : 15:30
