Description: Starbucks,
Inc. has hired you to create an application that will help
their customers pre-order coffee for one week. In this test
environment, Starbucks has elected to use a selected set of
coffees for this application. The program will offer the customer
their
choice of a Cappuccino, or a Frappuccino, or a Latte'. All
coffee comes in three sizes, "Tall", "Grande",
or "Venti". The program will ask the customer to
select a type of coffee and a size, then save both. Once the
customer has set their coffee selection for each day of the
week, the program will display their selections by day of the
week.
Here is a sample
of the program without errors:
Welcome to Starbucks! I'm your starbucks assistant and I will
help you create your weekly starbucks coffee schedule.
To start week need to know what your coffee preferences are
for each day of the week. Let's start with
Sunday:
Would you
prefer a Latte', a Cappuccino, or a Frappucino?
Please select 1 for a Latte', 2 for a Cappuccino, or 3 for
a Frappucino
1
What size coffee would you like?
Please select 1 for a Tall, 2 for a Grande, or 3 for Venti
1
Monday:
Would you prefer a Latte', a Cappuccino, or a Frappucino?
Please select 1 for a Latte', 2 for a Cappuccino, or 3
for a Frappucino
2
What size coffee would you like?
Please select 1 for a Tall, 2 for a Grande, or 3 for Venti
2
(Continues through the rest of the week)
The following coffee
selections will be delivered to your home or office. Thank
you for choosing Starbucks!
Sunday:
Tall Latte'
Monday:
Grande Cappuccino
Tuesday: Venti Frappuccino
Wednesday: Tall
Latte'
Thursday: Grande Cappuccino
Friday: Venti Frappuccino
Saturday:
Tall Latte'
Assumptions:
You may assume that all input is a number, either positive
or negative.
You should use the famous EasyIn class to read the user's input
Requirements:
1) You must declare
a two-dimensional array for the customer's coffee selection
on each day of the week. The declaration is
as follows:
String[][] coffeeSelection = new String[7][2];
For simplicity, I used three additional arrays, one to store
the days of the week, one to store the type of coffee and one
to store the sizes.
2) You must use
the EasyIn class to handle user input.
3) All output to must come from the StarbucksUtil class.
This class will contain utility methods that can
be used by the StarbucksAssistant class. You are required
to have two scheduleMessage() methods, and can choose what
other methods you need. However, I have provided my class
diagram if you want to use it as a guide. The class diagram
for my StarbucksUtil is as follows:
Note:
The overloaded method called scheduleMessage() and
the signatures are as follows:
public static void scheduleMessage();
public static void scheduleMessage(String[] daysOfWeek, String[][]
coffeeSelection);
The
first method displays the message,
"The
following coffee selections will be delivered to your home
or office.
Thank
you for choosing Starbucks!"
and
the second displays the user's coffee selection by day of
the week. Sunday:
Tall Latte'
Monday: Grande Cappuccino
Tuesday: Venti Latte'
Wednesday:
Tall Latte'
Thursday: Tall Latte'
Friday: Tall Latte'
Saturday:
Tall Latte'
4)
Your program must account for errors in the coffee selection
and errors in the size selection. If a user makes an error,
the application should display an error message and prompt
the user for the information again, until a valid selection
is
made.
ALL ERROR MESSAGE MUST START WITH "ERROR:",
then an explanation of the problem. Remember, I said you
can assume that all
input as numbers. Below are
examples
of the two errors, one in coffee selection and one in size
selection:
Coffee
Selection Error: Sunday:
Would you prefer a Latte', a Cappuccino,
or a Frappucino?
Please select 1 for a Latte', 2 for a Cappuccino, or 3 for
a Frappucino
5
ERROR: You have selected an invalid drink for Sunday
Would you
prefer a Latte', a Cappuccino, or a Frappucino?
Please select 1 for a Latte', 2 for a Cappuccino, or 3 for
a Frappucino
Size Selection Error:
What size coffee would you like?
Please select 1 for a Tall, 2 for a Grande, or 3 for Venti
23
ERROR: You have selected an invalid size for Sunday!
What
size coffee would you like?
Please select 1 for a Tall, 2 for a Grande, or 3 for Venti
Your
application should repeat this process until a valid
selection has been made.
5)You are required to
properly comment your code with JavaDoc comments. This means
the class and all methods should have JavaDoc comments. StarbucksAssistant.java
and StarbucksUtil.java only. The JavaDoc for the my application
can be seen here.
Objectives:
* Be able to create Java application which runs directly on the system and NOT from a HTML
file.
* Understand flow control structures. This application uses nested loops
and nested if/else statements.
* Understand static methods and utility class definitions.
* Understand multi-dimensional arrays.
