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);
}
}
