2. The method
sameName
is not listed in the class diagram for
Student
. So, you
follow the arrow to the class diagram for
Person
. The method
sameName
with a
single parameter of type
Person
is in the class diagram for
Person
. Because you
know a
Student
is a
Person
, you know that this definition works for the method
sameName
with a single parameter of type
Student
. So, the definition used for the
method
sameName
is in the class definition of
Person
.
3. You start at the class diagram for
Student
. The method
setStudentNumber
with a
single parameter of type
int
is in the class diagram for
Student
, so you need look
no further. The definition used for the method
setStudentNumber
is in the class
definition of
Student
.
