Assume that the following is a method in class LinkedListExample and class KWLinkedList as explained in the lectures is available for use. What does the following non-member method do? public static void uknownMethod( KWLinkedList list1, E value1, E value2)

{

ListIterator iter = list1.listIterator();

int i;

while (iter. hasNext())

{

if (iter. next().equals(value1))

i = iter. nextIndex();

list1.add(i-1, value2);

}

}

If value1 exists in list1, then it adds value2 before one node from value1 in list1.

If value1 exists in list1, then it adds value2 after one node from value1 in list1.

If value1 exists in list1, then it adds value2 after value1 in list1.

If value1 exists in list1, then it adds value2 before value1 in list1.

8. create an abstract student class for parker university. the class contains fields for student id number, last name, and annual tuition. include a constructor that requires parameters for the id number and name. include get and set methods for each field; the settuition() method is abstract. create three student subclasses named undergraduatestudent, graduatestudent, and studentatlarge, each with a unique settuition() method. tuition for an undergraduatestudent is $4,000 per semester, tuition for a graduatestudent is $6,000 per semester, and tuition for a studentatlarge is $2,000 per semester. write an application that creates an array of at least six objects to demonstrate how the methods work for objects for each student type. save the files as student. java, undergraduatestudent. java, graduatestudent. java, studentatlarge. java, and studentdemo. java.
