SOLUTION 4.1
Your diagram should look something like Figure B.3.
Figure B.3. This diagram shows the flight path application factored into one class for
calculating a flight path, one for displaying a flight path, and one that simplifies use of the
Swing libraries.
Note that all the methods of
SwingFacade
are static methods. Does your solution make
these methods static? If not, why not?
SOLUTION 4.2 (
from page 47
