I need help modifying my code.

ShoppingCart.java - Class definition

ShoppingCartManager.java - Contains main() method

1. Build the ShoppingCart class with the following specifications. Note: Some can be method stubs (empty methods) initially, to be completed in later steps.

Private fields:

-String customerName - Initialized in default constructor to "none"

-String currentDate - Initialized in default constructor to "January 1, 2016"

-ArrayList cartItems

-Default constructor

-Parameterized constructor which takes the customer name and date as parameters

Public member methods:

-getCustomerName() accessor (1 pt)

getDate() accessor (1 pt)

addItem()

-Adds an item to cartItems array. Has parameter ItemToPurchase. Does not return anything.

removeItem()

-Deletes item from cartItems array. Has a string (an item's name) parameter. Does not return anything.

-If item name cannot be found, output this message: Item not found in cart. Nothing deleted.

modifyItem()

-Modifies an item's description, price, and/or quantity. Has parameter ItemToPurchase. Does not return anything.

-If item can be found (by name) in cart, check if parameter has default values for description, price, and quantity. If not, modify item in cart.

-If item cannot be found (by name) in cart, output this message: Item not found in cart. Nothing modified.

getNumItemsInCart() (2 pts)

-Returns quantity of all items in cart. Has no parameters. g

etCostOfCart() (2 pts)

-Determines and returns the total cost of items in cart. Has no parameters.

printTotal()

-Outputs total of objects in cart. If cart is empty, output this message: SHOPPING CART IS EMPTY

printDescriptions()

-Outputs each item's description my code for ItemToPurchase.java

public class ItemToPurchase { //Private fields private String itemName; private String itemDescription; private int itemPrice; private int itemQuantity; public ItemToPurchase() { //Default constructors String itemDescription = "none"; itemName = "none"; itemQuantity = 0; itemPrice = 0; } //Parameterized constructor to assign name,descptn, price, quanitity public ItemToPurchase(String ItemName, String ItemDescription, int ItemPrice, int ItemQuantity) { //"this" refers to the object that is calling the method in the first place/reference this.itemDescription = ItemDescription; this.itemName = ItemName; this.itemPrice = ItemPrice; this.itemQuantity = ItemQuantity; } //Public member methods public String itemDescription() { return itemDescription; } //Outputs the item name followed by the quantity, price, and subtotal public void printItemCost() { System.out.println(itemName + " " + itemQuantity + " @ " + itemPrice + " = $" + (itemQuantity * itemPrice)); } public void printItemDescription() { System.out.println(itemName + " " + itemDescription); } public void getDescription(String itemDescription) { this.itemDescription = itemDescription; } public String getName() { return itemName; } public void setName(String itemName) { this.itemName = itemName; } public int getPrice() { return itemPrice; } public void setPrice(int itemPrice) { this.itemPrice = itemPrice; } public int getQuantity() { return itemQuantity; } public void setQuantity(int itemQuantity) { this.itemQuantity = itemQuantity; } }

my code for ShoppingCart.java

import java.util.ArrayList;

Has parameter ItemToPurchase. Does not return anything. public void addItem( ItemToPurchase i) { cartItems.add(i); } //Removes item from cartItems array. Has a string (an item's name) parameter.

Has no parameters. public double getCostOfCart() { int sum = 0; for(ItemToPurchase i: cartItems){ sum = sum + i.getPrice(); } return sum; } //Outputs total of objects in cart. public void printTotal(){ if(cartItems!=null&& cartItems.size() >0 ){ System.out.println(customerName + "'s Shopping Cart - " + currentDate); System.out.println("Number of Items: " + cartItems.size()); System.out.println(); for(ItemToPurchase i: cartItems){ i.printItemCost(); } } else{ System.out.println("SHOPPING CART IS EMPTY"); } } //Outputs each item's description. public void printDescriptions() { System.out.println(customerName+"'s Shopping Cart - "+currentDate); System.out.println("Number of Items: " + cartItems.size()); System.out.println(); System.out.println("Item Descriptions"); for(ItemToPurchase i: cartItems){ i.printItemDescription(); } } }

my code for ShoppingCartManager.java

import java.util.Scanner;
