Question

Write an abstract superclass encapsulating a student. This
abstract superclass named Student has two data fields:
student’s ID and annual tuition. This abstract class has two
nonabstract subclasses: one encapsulating undergraduate
students named Undergraduateclass, and the other
encapsulating graduate students named Graduate. This
abstract superclass also has a getTuition() method and a
setTuition(int tuition) method. The setTuition(int tuition) is only
an abstract method.

In Java

The Undergraduate class has two additional data fields: name
and GPA. This class has also its own setTuition(int tuition)
method .The Graduate class has one additional attribute:
major. It also has its own setTuition(int tuition) method.

You also need to include a class to test these two classes.
Create an object from each subclass and call a method if any
subclass has it.

Each class should have its own constructor and String toString()
method.
