Homework SourseI AM TRYING TO MODIFY MY PROGRAM BELOW TO IMPLEMENT THE TIME
I AM TRYING TO MODIFY MY PROGRAM BELOW TO IMPLEMENT THE TIME AS A NUMBER OF SECONDS SINCE MIDNIGHT AND SHOW THAT THERE IS NO VISIBLE CHANGE IN FUNCTIONALITY TO THE CLIENTS OF THE CLASS RATHER THAN THE THREE INTEGER VALUES HOUR, MINUTE, AND SECOND WHILE CLIENTS USE THE SAME PUBLIC METHODS AND GET THE SAME RESULTS. (USING THE VIRTUES OF IMPLEMENTATION HIDING).
