CIS 331 – Spring 2019

HW #3 Duke Dining Application

Scenario: You will be writing a Java application that simulates a customer building a custom

Combo lunch plate in the JMU D-Hall.

Business Domain Knowledge:

Here are the prices that D-Hall charges for the various items on the Combo plate:

Sandwiches:

Veggie: $1.50

Chicken: $2.50

Beef: $2.00

Turkey: $1.80

A customer can have two side items on their plate. They choose two from this list:

Fries $0.50

Salad $0.70

Soup $1.50

Steamed Rice $0.40

Finally they can choose a drink:

Water: $0.20

Soft Drink: $1.70

Milk: $2.50

Berry Fizz: $1.20

D-Hall has several “Healthy” promotions going on:

If the customer selects the Chicken sandwich for lunch, they get a 20% discount on the

cost of their first side item.

If the customer chooses

o The Veggie sandwich, and

o Either the Soup or Rice for both sides (in any combination), and

o Water as their drink

They will then get a 30% discount on the entire order before taxes are calculated.

Your program should prompt the customer for each of the choices above (Sandwich, first Side,

second Side, and Drink), display a subtotal, display any discounts that apply to their order,

display the taxes, and then the total due at the end (See the example output below).

Requirements:

This is an individual homework assignment.

Your application should adhere to the above requirements, function as requested, and all

calculations should be correct.

Use .printf( ) to round all monetary amounts to 2 decimal places.

Include a comment header at the top of your .java file.

Comment sufficiently but not excessively.

Remember: The customer can select any of the four options for each and every food item.

There are many many different Combo plates that can be built with these!

Due: Wednesday, January 23rd by 11:59 p.m. Worth: 20 Homework Points
