This is my code so far.

Shopping Cart Manager:

import java.util.Scanner;

public class ShoppingCartManager { public static void main(String[] args) { String customerName, currentDate; Scanner sc = new Scanner(System.in); System.out.print("Enter Customer's Name:"); customerName = sc.nextLine().toString().trim(); System.out.println(); System.out.print("Enter Today's Date:"); currentDate = sc.nextLine().toString().trim(); System.out.println();

ShoppingCart cart = new ShoppingCart(customerName, currentDate); System.out.println("Customer Name:" + cart.getcustomerName()); System.out.println("Today's Date:" + ShoppingCart.getcurrentDate()); printMenu(cart); }

/** * Prints the menu, and builds the shopping cart * object passed in as parameter */ private static void printMenu(ShoppingCart cart) { Scanner sc = new Scanner(System.in); char choice = 'z'; System.out.println("MENU:"); System.out.println("a - Add Item To Cart"); System.out.println("d - Remove Item from Cart"); System.out.println("c - Change Item Quantity"); System.out.println("i - Output Items' Description"); System.out.println("o - Output Shopping Cart"); System.out.println("q - Quit"); System.out.print("Enter an option:"); choice = sc.nextLine().trim().charAt(0); while(choice != 'q') { if(choice != 'a' && choice != 'd' && choice != 'c' && choice != 'i' && choice != 'o') { //An invalid choice is made //Prompt for choice again System.out.print("Enter an option:"); choice = sc.nextLine().trim().charAt(0); continue; } else { switch (choice) { case 'o': { System.out.println("OUTPUT SHOPPING CART"); cart.printTotal(); break; }

case 'i': { System.out.println("OUTPUT ITEMS' DESCRIPTIONS"); cart.printDescriptions(); break; }

case 'a': { String name, desc; int price, qty; System.out.println("ADD ITEM TO CART"); System.out.println("Enter Item name:"); name = sc.nextLine().trim().toString(); System.out.println("Enter Item description:"); desc = sc.nextLine().trim().toString(); System.out.println("Enter Item price:"); price = sc.nextInt(); sc.nextLine(); System.out.println("Enter Item quantity:"); qty = sc.nextInt(); sc.nextLine();

ItemToPurchase itemToPurchase = new ItemToPurchase(name, desc, qty, price); cart.addItem(itemToPurchase); break; }

case 'd': { String itemToRemove; System.out.println("REMOVE ITEM FROM CART"); System.out.println("Enter name of item to remove:"); itemToRemove = sc.nextLine().trim().toString(); cart.removeItem(itemToRemove); break; }

case 'c': { String itemName; int itemQty; System.out.println("CHANGE ITEM QUANTITY"); System.out.println("Enter item name:"); itemName = sc.nextLine().trim().toString(); System.out.println("Enter the new quantity:"); itemQty = sc.nextInt(); sc.nextLine();

ItemToPurchase item = new ItemToPurchase(itemName, "none", itemQty, 0); cart.modifyItem(item); break; } } System.out.print("Enter an option:"); choice = sc.nextLine().trim().charAt(0); } } } }

ShoppingCart:

import java.util.ArrayList;

public class ShoppingCart { // Private fields private String customerName; private String currentDate; private ArrayList cartItems;

public ShoppingCart() { this.customerName = "none"; this.currentDate = "January 1, 2016"; cartItems = new ArrayList(); }

public ShoppingCart(String customerName, String currentDate) { this.customerName = customerName; this.currentDate = currentDate; cartItems = new ArrayList(); }

public String getCustomerName() { return customerName; }

public String getCurrentDate() { return currentDate; }

public void addItem(ItemToPurchase item) { cartItems.add(item); }

public void removeItem(String itemName) { boolean found = false; for (int i = 0; i

public int getNumItemsInCart() { int numItems = 0; for (ItemToPurchase item : cartItems) { numItems += item.getItemQuantity(); } return numItems; }

public int getCostOfCart() { int ttlCost = 0; for (ItemToPurchase item : cartItems) { ttlCost += item.getItemQuantity() * item.getItemPrice(); } return ttlCost; }

public void printTotal() { if (cartItems.size() == 0) System.out.println("SHOPPING CART IS EMPTY"); else { System.out.println(this.customerName + "'s" + " Shopping Cart - " + this.currentDate); System.out.println("Number of Items: " + this.cartItems.size()); for (ItemToPurchase item : cartItems) { item.printItemCost(); } System.out.println("Total: $" + getCostOfCart()); } }

public void printDescriptions() { if (cartItems.size() == 0) System.out.println("SHOPPING CART IS EMPTY"); else { System.out.println(this.customerName + "'s " + "Shopping Cart - " + this.currentDate); System.out.println("Item Descriptions"); for (ItemToPurchase item : cartItems) { item.printItemDescription(); } } } }

ItemsToPurchase:

public class ItemToPurchase { // Declare the private fields private String itemName; private int itemPrice; private int itemQuantity; private String itemDescription;

// DEFAULT CONSTRUCTOR public ItemToPurchase() { this.itemName = "none"; this.itemPrice = 0; this.itemQuantity = 0; this.itemDescription = "none"; }

public ItemToPurchase(String itemName, int itemPrice, int itemQuantity, String itemDescription) { this.itemName = itemName; this.itemPrice = itemPrice; this.itemQuantity = itemQuantity; this.itemDescription = itemDescription; }

public String getItemName() { return itemName; }

public void setItemName(String itemName) { this.itemName = itemName; }

public int getItemPrice() { return itemPrice; }

public void setItemPrice(int itemPrice) { this.itemPrice = itemPrice; }

public int getItemQuantity() { return itemQuantity; }

public void setItemQuantity(int itemQuantity) { this.itemQuantity = itemQuantity; }

public String getItemDescription() { return itemDescription; }

public void setItemDescription( String itemDescription) { this.itemDescription = itemDescription; }

public void printItemCost() { System.out.println(this.itemName + " " + this.itemQuantity + " @ $" + this.itemPrice + " = $" + (this.itemQuantity * this.itemPrice)); }

public void printItemDescription() { System.out.println(this.itemName + ": " + this.itemDescription); }

}

I cannot seem to get this to work. The program that assess it's accuracy is extremely strict. Cannot import any utilities other than the ones I have.

7.20 Ch 7 Program: Online shopping cart (continued) (Java) Note: Crealing muliple Scanner objecis for the sarne input strea yields unexpecled behavior. Thus, good practice is to use a single Scanner objecl for reading inpul from Systein.
