Question

First level CS, should not be too complex. Need in a week.

You must turn in three java files - FoodItem.java, Order.java and MyOrder.java. In addition to these, you must include a screenshot of the output by executing the file MyOrder.java. Submissions without all these files will not be graded.

Task 1:

Design a class named FoodItem which contains the following fields:

Type of food item: Like entree, bread, soup, salad, drink or dessert to name a few

Item number: could be an alphanumeric code or just a number

Unit price: $xx.xx

You must include appropriate instance methods like constructors, getters , setters and toString for all the fields.

Task 2:

Create another class named Order which has the following fields:

Order number: It could be an alphanumeric id or numeric.

Customer Name: First and last name of the customer

Combo meal option: yes or no

DiscountAmount: If combo meal is chosen, offer a 5% discount

OrderTotal: Total bill amount

You must create the following methods for the Order class:

Constructor (s) - You may include an extra constructor that takes in the Customer name as a parameter.

Setters, getters and toString methods for the appropriate fields.

add(item,quantity) - this method adds the price of purchasing an item to the Order total.

getOrderTotal() - this method returns the total bill amount to be paid by the customer after including any discounts applicable and also a 10% sales tax on the total amount.

Task 3:

Create a class named MyOrder that displays a Menu of items available to choose from, creates an order for two different customers and reports their total bill amount. Use appropriate print statements to guide the user through the ordering process. Remember, this is the class where you are actually placing an order (action required). So, this class must contain the main method.
