Java:

Consider the Time2 class discussed in the course textbook (Figure 8.5). An alternate implementation of this class could represent the time internally as the number of seconds since midnight rather than the three integer variables hour, minute, and second. Clients could still use the same public methods and get the same functionality from the class. Modify the internal representation of time in the Time2 class as described above. Write an application called TestTime2 that exercises the methods of the Time2 class to show that there are no visible changes to clients of the Time2 class.
