Grocery shopping list (LinkedList) 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

---ShoppingList. java:
import java. util. Scanner;
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

}
}

---ListItem. java:
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);
}
}
