Question

Java

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:

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
