I need help with the following Java assignment:

Modify the Date class so that it includes a compareTo method with signature

int compareTo(Date anotherDate)

This method should return the value 0 if this date (the date of the object upon which the method is invoked) is equal to the argument date; a value less than 0 if this date is a date earlier than the argument date; and a value greater than 0 if this date is a date later than the argument date. Create a test driver that shows that your method performs correctly.
