(Time Class Modification) It would be perfectly reasonable for the Time class of Figs. 17.4–17.5 to represent the time internally as the number of seconds since midnight rather than the threeinteger values hour, minute and second. Clients could use the same public methods and get thesame results. Modify the Time class of Fig. 17.4 to implement the time as the number of secondssince midnight and show that there is no visible change in functionality to the clients of the class.[Note: This exercise nicely demonstrates the virtues of implementation hiding.]

Question
(Time Class Modification) It would be perfectly reasonable for the Time class of Figs. 17.4–
17.5 to represent the time internally as the number of seconds since midnight rather than the three
integer values hour, minute and second. Clients could use the same public methods and get the
same results. Modify the Time class of Fig. 17.4 to implement the time as the number of seconds
since midnight and show that there is no visible change in functionality to the clients of the class.
[Note: This exercise nicely demonstrates the virtues of implementation hiding.]
