Given main() in the Inventory class, define an insertAtFront() method in the InventoryNode class that inserts items at the front of a linked list (after the dummy head node). Ex. If the input is: 4 plates 100 spoons 200 cups 150 forks 200 the output is: 200 forks 150 cups 200 spoons 100 plates
import java.util.Scanner;
public class Inventory {
public static void main (String[] args) {
Scanner scnr = new Scanner(System.in);
InventoryNode headNode;
InventoryNode currNode;
InventoryNode lastNode;
String item;
int numberOfItems;
int i;
// Front of nodes list
headNode = new InventoryNode();
lastNode = headNode;
int input = scnr.nextInt();
for(i = 0; i < input; i++ ) {
item = scnr.next();
numberOfItems = scnr.nextInt();
currNode = new InventoryNode(item, numberOfItems);
currNode.insertAtFront(headNode, currNode);
lastNode = currNode;
}
// Print linked list
currNode = headNode.getNext();
while (currNode != null) {
currNode.printNodeData();
currNode = currNode.getNext();
}
}
}
