class definitions in this Module. For these exercises you are required edit in the Comparable interface implementation, a compareTo() method, starting with the class definition you obtained from the link, and submit that with a client that uses this ordering. If you are so inclined, you may submit a single client to drive your ordering enhancements for both classes, rather than one for each class. The exercises, for those without the text: 19. Modify the Point class from Chapter 8 so that it defines a natural ordering by implementing the Comparable interface. Compare the Points by y-major order; that is, points with smaller y-coordinate values should come before those with higher y-coordinate values. Break ties by comparing x-coordinate values. 20. Modify the TimeSpan class from Chapter 8 to include a compareTo method that compares time spans by their length. A time span that represents a shorter amount of time is considered to be "less than" one that represents a longer amount of time. For example, a span of 3 hours and 15 minutes is greater than a span of 1 hour and 40 minutes
