Trying this again since part of my question keeps disappearing Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts

Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node.
Ex. if the input is:
4 Kale Lettuce Carrots Peanuts
where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list.
The output is:

// Constructor

this.nextNodeRef = null;
}
// Constructor
public ItemNode(String itemInit, ItemNode nextLoc) {
this.item = itemInit;
this.nextNodeRef = nextLoc;
}
// Insert node after this node.
public void insertAfter(ItemNode nodeLoc) {
ItemNode tmpNext;
tmpNext = this.nextNodeRef;
this.nextNodeRef = nodeLoc;
nodeLoc.nextNodeRef = tmpNext;
}
// TODO: Define insertAtEnd() method that inserts a node

public ItemNode getNext() {
return this.nextNodeRef;
}
public void printNodeData() {
System.out.println(this.item);
