b. Write a private method isValid(hour, minute) that returns true if the given hour and minute values are in the appropriate range.

c. Write a method setTime(hour, minute) that sets the time if the given values are valid.

d. Write another method setTime(hour, minute, isAM) that sets the time if the given values are valid. The given hour should be in the range 1 to 12. The parameters isAM is true if the time is in a.m. time and false otherwise.
