[Solved]Java Assignment Following Classes Need Modified Public Class Item Protected String Itemnam Q37227975

For this Java assignment, I have the following classes that needto be modified.

public class Item {

   protected String itemName;
   protected int itemQuantity;
  
   public void setName(String newName) {
       itemName = newName;
       return;
   }

   public void setQuantity(int newQty) {
       itemQuantity = newQty;
       return;
   }

   public void printItem() {
      System.out.println(this.toString());     
       //return;
   }

   public String toString() {
       return itemName + ” ” +itemQuantity ;
   }
}

import java.util.ArrayList;

public class ShoppingCart {
   private ArrayList<Item> items;
  
   public ShoppingCart() {
       items = newArrayList<Item>();
   }
  
  
   public void addItem(Item item) {
       items.add(item);
   }
  
   public void displayCart() {
       for(Item item : items)
          item.printItem();
   }

}

1. Add an attribute price (double) to Item. Add a setter method.Note that since Item is the Base class of GroceryItem,ImportedGroceryItem, and VirtualItem, the attribute and the settermethod are automatically inherited (how wonderful!)
2. Modify the method toString to add the price to the result
3. Next implement a method calculateTotal, also in item. Thismethod returns the price * quantity of the item
4. In ShoppingCart, implement the method getTotal. This methodreturns the total price of all items in the cart
5. Now, implement the method getGroceryTotal. This method returnsthe total price of grocery items in the cart
6. Similarly, implement the method getNonGroceryTotal. This methodreturns the total price of non-grocery items in the cart

Hint to differentiate between groceryand non-grocery items, you can use the instanceof operator objectinstanceof Class evaluates to true or false. For example, if(iteminstanceof GroceryItem) {….}

I need to print something output something like this belowhighlighted in black.

A virtual item cannot have a quantity more than1

Pencil 10 $0.99

Notepad 3 $1.99

Apple 5 $0.49 2017-11-11

Mango 10 $1.25 2017-12-1

imported from Mexico Wonder Woman 1 $9.992000.0MB

Total price of all items is $40.81

Total price of grocery items is $14.95

Total price of non grocery items is$25.860000000000003
