Transitive Relation?
Exercise Would it be possible to create a chain of inheritance relationships as in the following example?
(a) Yes
(b) No

Solution
Yes! Inheritance is transitive. If GradStudent
is a subclass of Student
and PhdStudent
is a subclass of GradStudent
, then PhdStudent
is also a subclass of Student
.
The chain of inheritance relationships is known as "multilevel inheritance" (where a subclass is inherited from another subclass).
Multilevel inheritance is supported in Java.
