ShoppingList Class
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
LinkedList<String> shoppingList = new LinkedList<String>();
String item;
// TODO: Scan inputs (items) and add them to the shoppingList LinkedList
// Read inputs until a -1 is input
item = scnr.next();
while (!item.equals("-1")) {
shoppingList.add(item);

for (int i = 0; i < shoppingList.size(); i ++) {
ListItem list = new ListItem();
list.listItem();
list.printNodeData();
}
}
}
ListItem Class
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);
}
}
ListItem Class
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);
}
}
I am able to add the items to the shopping list but I have been stuck on trying to print the list using the printNodeData method that is in the ListItem class.
