Reference no: EM13165202

created a linkedlist class,the set() method and listiterator() method. I need someone to finish for me.

 

here is what i got so far:

 

import java.util.Iterator;

import java.util.ListIterator;

import java.util.NoSuchElementException;

 

 

public class MyLinkedList<Product> {

private Node<Product> head = null;

private Node<Product> tail = null;

private Node<Product> temp = null;

 

private int counter = 0;

public MyLinkedList() {

}

public int size(){return counter;}

 

public Product get(int position){

assert (position >= 0 && position < size());

temp = head;

for(int i = 0; i < position; i++) temp = temp.next;

return temp.element;

}

 

public void add(Product element) {

if (head == null) {

head = tail = new Node<Product>();

head.element = element;

head.next = tail;

tail = head;

}else{

tail.next = new Node<Product>();

tail = tail.next;

tail.element = element;

}

counter++;

 

}

 

/*public void set(int position, Product element) {

if (position == size()) {

add(element);

return;

} else if (position == 0) {

 

}

 

}*/

public void set(int inLayer, Product element) {

if (head == null) {

head = tail = new Node<Product>();

head.element = element;

head.next = tail;

tail = head;

}else{

tail.next = new Node<Product>();

tail = tail.next;

tail.element = element;

}

counter++;

}

public ListIterator<Product> iterator() {

return ListIterator<Product>();

}

Node<Product> current = head;

 

boolean hasNext() {

return (current.next != null);

}

 

Product next() {

if (!hasNext()) {

throw new NoSuchElementException();

}

current = current.next;

return current.value;

}
