Given a ListItem class, complete main() using the built-in LinkedList type to create a linked list called shoppingList. The program should read items from input (ending with -1), adding each item to shoppingList, and output each item in shoppingList using the printNodeData() method. Ex. If the input is: milk bread eggs waffles cereal -1 the output is: milk bread eggs waffles cereal Current file: ShoppingList. java Load default template... 1 import java. util. Scanner; 2 import java. util. LinkedList; public class ShoppingList { public static void main (String[] args) { Scanner scnr = new Scanner(System. in); // TODO: Declare a Linkedlist called shoppingList of type ListItem String item; // TODO: Scan inputs (items) and add them to the shoppingList LinkedList // Read inputs until a -1 is input // TODO: Print the shoppingList LinkedList using the printNodeData() method 20 } File is marked as read only Current file: ListItem. java 1 public class ListItem { private String item; public ListItem() { item = ""; public ListItem(String itemInit) { this. item = itemInit; // Print this node public void printNodeData() { System. out. println(this. item);
