Draw an inheritance hierarchy for students at a university similar to the hierarchy shown in Fig 9.2 . Use Student as the superclass of the hierarchy, then extend Student with classes UndergraduateStudent and CraduateStudent. Continue to extend the hierarchy as deep (i.e., as many levels) as possible. For example, Freshman, Sophomore, Junior and Senior might extend UndergraduateStudent, and Doctoralstudent and MastersStudent might be subclasses of GraduateStudent. After drawing the hierarchy, di

SOLVED: (a) Create an inheritance hierarchy of Rodents: Mouse, Gerbil, Hamster, etc. In the base class, provide methods that are common to all Rodents, and override these in the derived classes to perform different behaviors depending on the specific type of Rodent. Create an array of Rodents, fill it with different specific types of Rodents, and call your base-class methods to see what happens.(b) Create a Cycle class, with subclasses Unicycle, Bicycle, and Tricycle. Demonstrate that an instanc
