    public static void main(String... args) {
        long numberOfHours = 2;

        // Convert Number of Hours to Seconds
        long numberOfSeconds = Duration.ofHours(numberOfHours).toSeconds();

        System.out.println("Number of hours: " + numberOfHours);
        System.out.println("Number of seconds: " + numberOfSeconds);
