2) Implement a SinglyLinkedList class that implements the interface List to store elements of a generic type: (i.e., public class SinglyLinkedList > implements List). Just as in the lectures, the class must have a nested static class called Node that stores the generic value and a reference variable next that points to the next node in the list. Here are the methods included in the interface: 1) public int size(); returns the size of the list (must be implemented as a recursive method).

2) public T get(int i); returns the element at position i (first position index is 0).

3) public int indexOf(Object item); returns the position of item ( note that it is of type objects).

4) public void add(int i, T item); adds item at position i of the list.

5) public T remove(int i); removes item at position i of the list.

6a) public T min(); returns the item with the minimum value in the list;

6b) public T minR(); returns the item with the minimum value in the list (must be implemented as a recursive method);

7a) public T max(); returns the item with the maximum value in the list;

7B) public T maxR(); returns the item with the maximum value in the list (must be implemented as a recursive method);

8) public boolean Empty(): returns true if the list is empty.

9) public void addAthead(T item) : adds an element at the head of the list

10) public void addAtEnd(T item): adds an element at the end of the list.

11) public void replace(T first, T second): takes two elements as an input, searches for the first(first) in the list, if it is found it will replace it with second ( without creating an nodes).

12) public List duplicate(T item): A recursive method to duplicate every element in a linked list, that is equal to a certain value. For example, if the linked list contains 4, 8, 4, 10 the element to duplicate is 4 the new list should contain 4,4,8,4,4, 10.

13) public void reverse(): A recursive method that prints out the data elements of a linked list in reverse order.

14) public List countGreaterThan(T threshold): A recursive method that returns a list containing all the elements in the original list that are larger than threshold.

15) public Boolean equals(Object other): A recursive method returns true if other is a list that has the same elements in the list with the same order.

16) public String toString(): returns a string representation of the elements in the list separated by a comm..

17) public List inorder(); returns a new list that has all the elements in the list sorted in an ascending order.

18) public void removeEven(): removes all the elements at even positions from the list (0,2, 4, ..) and keeps only the elements at the odd positions.

plz help solving part 3,9,10,11,13,15,17,18 if possible
