The program appears in a class called DrawFigures2 and has four static methods
defined within it. The first static method is the usual main method, which calls three
methods. The three methods called by main appear next.
Figure 1.3 is a structure diagram for this version of the program. Notice that it has
two levels of structure. The overall problem is broken down into three subtasks.
