2. Consider a class Time that represents a time of day. It has attributes for the hour and minute. The hour value ranges from 0 to 23, where the range 0 to 11 represents a time before noon. The minute value ranges from 0 to 59. a. Write a default constructor that initializes the time to 0 hours, O minutes. 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 setTi me (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 I to 12. The parameter isAm is true if the time is an a.m. time and false otherwise
