MyLinkedList list1 = new MyLinkedList();

I need help with the question 6 and 8

5. Add a new PartTime student at index 2 in the list then remove the student at index 1 from the list. Display the list 6. Check if the newly added PartTime student is in the list using contains method, then display its index which should be 1. // contains, indexOf 7. Change the title of the name of the newly added student to John Doe. // set 8. Construct a MyLinkedList object from an array of mixed students then display the list.

public interface MyList { public void clear(); public boolean isEmpty(); public boolean contains(E object); public int indexOf(E object); public E get(int index); public E set(E e, int index); public int size(); public void add(int index, E object); public E remove(int index); }

public interface MyList {

public void clear();

public boolean isEmpty();

public boolean contains(E object);

public int indexOf(E object);

public E get(int index);

public E set(E e, int index);

public int size();

public void add(int index, E object);

public E remove(int index);

}
