public void setAlarm(int hour, int minute, boolean am)

Sets alarm to the 24-hour clock value of hour:minute with am determining whether the hour is am or pm. Note that hour is the 12-hour equivalent. If hour and/or minute are not valid (must be 0 <= hour <= 12, 0 <= minute <= 59), prints an error and doesnt change alarm time from its previous value.

Note that setAlarm should only change the alarm time and not other aspects of the

state.

How would I create this public method?
