Coding 5 - Classes The Item class is defined for you. See the bottom of the file to see how we will run the code. Define a class ShoppingCart which supports the following functions: add_item(), get_total_price(), and print_summary(). Write code only where the three TODO's are. Below is the expected output: Added 2 Pizza(s) to Cart, at $13.12 each. Added 1 Soap(s) to Cart, at $2.25 each. Added 5 Cookie(s) to Cart, at $3.77 each.

Explanation:

The following is written in Java. It creates the ShoppingCart class as requested and implements the requested methods. A test class has been added to the main method and the output is highlighted in red down below.

import java.util.ArrayList;

import java.util.Scanner;

class {

   public static void main(String[] args) {

       ShoppingCart newCart = new ShoppingCart();

       newCart.add_item();

       newCart.add_item();

       newCart.add_item();

       newCart.print_summary();

   }

}

class ShoppingCart {

   Scanner in = new Scanner(System.in);

   ArrayList<String> items = new ArrayList<>();

   ArrayList<Integer> amount = new ArrayList<>();

   ArrayList<Double> cost = new ArrayList<>();

   public ShoppingCart() {

   }

   public void add_item() {

       System.out.println("Enter Item:");

       this.items.add(this.in.next());

       System.out.println("Enter Item Amount:");

       this.amount.add(this.in.nextInt());

       System.out.println("Enter Cost Per Item:");

       this.cost.add(this.in.nextDouble());

   }

   public void get_total_price() {

       double total = 0;

       for (double price: cost) {

           total += price;

       }

       System.out.println("Total Cost: $" + total);

   }

   public void print_summary() {

       for (int i = 0; i < items.size(); i++) {

           System.out.println(amount.get(i) + " " + items.get(i) + " at " + cost.get(i) + " each.");

       }

       get_total_price();

   }

}
