• List all items purchased
• Price of each item
• Subtotal
• Total Tax (if any)
• Total (Subtotal + tax)
• Any company information at the bottom or top of receipt as well

Answer 1

import java.util.ArrayList;

class Item {
   private String name;
   private double price;
   private double tax;

   public Item(String aName, double aPrice, double aTax) {
       super();
       name = aName;
       price = aPrice;
       tax = aTax;
   }

   public String getName() {
       return name;
   }

   public void setName(String aName) {
       name = aName;
   }

   public double getPrice() {
       return price;
   }

   public void setPrice(double aPrice) {
       price = aPrice;
   }

   public double getTax() {
       return tax;
   }

   public void setTax(double aTax) {
       tax = aTax;
   }

   public String toString() {
       return name + " :" + price;
   }
}

public class Receipt {
   public static void main(String[] args) {
       ArrayList<Item> list = new ArrayList<Item>();
       list.add(new Item("Soap", 10, 0.05));
       list.add(new Item("Brush", 16, 0.05));
       list.add(new Item("Tv", 100, 0.1));
       double total = 0;
       double tax = 0;
       for (Item i : list) {
           total += i.getPrice();
           tax += i.getPrice() * i.getTax();
       }
       System.out.println("No of Items : " + list);
       System.out.println("Sub total : " + total);
       System.out.println("Tax : " + tax);
       System.out.println("Total : " + (tax + total));
   }
}
