Display 12.3 shows some possible additional details of the inheritance hierarchy for
the two classes Person and one of its derived classes, Student . Suppose s is an object
of the class Student . The diagram in Display 12.3 tells you that you can find the
definition of

s.toString();

and

s.set("Joe Student", 4242);
in the class Student , but the definition of

s.setName("Josephine Student");
is found in the definition of the class Person .
