(Student Inheritance Hierarchy) Draw an inheritance hierarchy for students at a universitysimilar to the hierarchy shown in Fig. 19.2. Use Student as the base class of the hierarchy, then include classes UndergraduateStudent and GraduateStudent that derive from Student. Continue toextend the hierarchy as deep (i.e., as many levels) as possible. For example, Freshman, Sophomore,Junior and Senior might derive from UndergraduateStudent, and DoctoralStudent and MastersStudent might derive from GraduateStudent. After drawing the hierarchy, discuss the relationships that exist between the classes. [Note: You do not need to write any code for this exercise.]

(Java) The Abstract Art Class Write an abstract class as follows: The class is named Art It inherits from the Comparable interface It has a private String member variable named name It has a private String member variable named artist It has a private int member variable called year It has a default constructor that assigns the values "No name" to name, "No artist" to artist and -1 to the year. This default constructor calls the three argument constructor. It has a three-argument constructor to assign values to the name, artist and year variables. It has a copy constructor that makes a copy of another non-null Art object It has getters and setters for the name, artist and year variables It has a toString() method that creates a string of artist, with name and year tabbed once on subsequent lines (see sample output) It has an equals method that compares this Art to another Object It has a compareTo method that compares in this order: 1) artist, 2) name, 3) year This class contains no…

The term "polymorphism" needs to be defined.
