Modify the Time2 class (below) to implement the time as the number of seconds since midnight. The class should have one data field (an int with the number of seconds since midnight) instead of three. This change should not affect the arguments, behavior, or output of the public methods.

Create a Driver class with a main method to test your Time2 class. This program should ask the user to input the number of hours, minutes, and seconds past midnight, creating a Time2 object and using the mutator methods. The program should then use the toString() method to print out the time.
