Inheritance Versus Interfaces (graded)
How are abstract classes similar to interfaces? How are they different? Explain a situation where you would use one instead of the other.
dq 2

iLab Forum (graded)
dq 1
Abstract Classes (graded)
An abstract class, although well defined, is one that is never instantiated. For example, a pet would never be instantiated as such, but could
exist in the form of a dog or a cat. The pet class would be at the top of an inheritance hierarchy where derived classes like the dog or cat
class inherit their attributes and behavior from the pet class. Can you give other examples of inheritance hierarchies where the top level is
an abstract class, and furthermore, what are the advantages of using such hierarchies?
dq 2
iLab Forum (graded)
dq 1
Reading a File (graded)

The java.io.* package contains two classes that work in concert to process data from a text file: the FileReader class and the
BufferedReader class. In what sense do they work in concert in the following statement.
BufferedReader buffer = new BufferedReader(new FileReader(“C:client.txt”))
Assuming the input file has multiple records, how would you process the entire file and how would you detect the end of file?
dq 2
iLab Forum (graded)

Lab Steps

STEP 1: SalesTracking.java
You must create a sales tracking program named SalesTracking.java. This program will use arrays to store and process monthly sales as
well as compute average yearly sales, total sales for the year, and which month had the highest sales and which month had the lowest
sales. You should use parallel arrays. Your first array (monthArray) should be initialized with all of the months. This array should have 12
locations of course. Your other array should be named monthlySales. Like your monthArray, this array should be 12 locations that store the
amount of sales for each month.
The program should prompt the user for the sales for each month starting with January. The arrays (monthlySales and monthArray) should
be created in main and passed to the methods as needed. Your program should have methods that do the following.
getSales(monthArray, monthlySales): This method receives the monthArray and monthlySales arrays as arguments. It prompts the users for
the sale for each month. This amount should be stored and returned into the corresponding location in the monthlySales array. For
example, January sales should be stored in the first location, February sales should be stored in the second location, and so forth.
computeTotalSales(monthlySales): This method receives the monthly sales array as an argument and returns the total sales of the year.
computeAverageSales(monthlySales): This method receives the monthly sales array as an argument and returns the average sales for the
year.
computeHighestMonth(monthlySales): This method receives the monthly sales array as an argument. This method will search and compare
the values of the monthly sales array for the highest value. The method will return the index(or location in the array) of the month with the
highest value.
computeLowestMonth(monthlySales): This method receives the monthly sales array as an argument. This method will search and compare
the values of the monthly sales array for the lowest value. The method will return the index (or location in the array) of the month with the
lowest value.
displaySaleInfo(totalSales, averageSales, highestMonth, highestSales, lowestMonth, lowestSales): This method will receive the total yearly
sales, average monthly sale, the month with the highest sales, as well as the sales for that month and the month with the lowest sales. This
method will display all of the data it received as arguments.
All methods should be STATIC therefore no object will need to be instantiated to call them. All methods must be called from the main
method. Sales amounts should be rounded to two decimal places. .
Your monthArray should have the following values.
monthArray

JANUARY FEBRUARY MARCH ….. ….. ….. NOVEMBER DECEMBER

Devry CIS 355A Full Course Project latest
All week course project

Developing a graphical user interface in programming is paramount to being successful in the business industry. This project incorporates
GUI techniques with other tools that you have learned about in this class.
Here is your assignment: You work for a flooring company. They have asked you to be a part of their team because they need a computer
programmer, analyst, and designer to aid them in tracking customer orders. Your skills will be needed in creating a GUI program that
calculates the flooring cost and stores the order in the database.
The project has three components: an analysis and design document, the project code, and a user manual. The analysis and design
document is due Week 4. The code and user manual are due in Week 7. It is suggested that you begin working on the code in Week 5,
which should give you ample time to complete the project. You will find that the lectures and lab assignments will prepare you for the
Course Project.
Guidelines
Your application must include at least three tabs. The user will choose wood flooring or carpet, enter the length and width of the floor, as
well as the customer name and address. The application will compute the area of the floor and the cost of the flooring considering that
wood floor is $20 per square foot and carpet is $10 per square foot. A summary should be displayed, either in a tab or another window,
listing the customer name and address, floor selection, area, and cost. This information should also be stored in the MySQL database table.
The program should validate that all information is entered and that the length and width are numeric values. Any numeric or currency
values must be formatted appropriately when output. Recommendations for the components used for input are
radio buttons—flooring type (wood or carpet);
text fields—customer name, customer address, floor length, and floor width; and
buttons—calculate area, calculate cost, submit order, display order summary, display order list.
The MySQL database table is called flooring and has the following description.
Field Type
CustomerName
varchar(30)
CustomerAddress varchar(50)
FlooringType

varchar(10)
FloorArea
double
FloorCost
double
In addition to entering new customer orders, your application should list all customer orders stored in the database. These will be viewed
as a list, in a text area, and will not be updated by the user.
Analysis and Design (Due Week 4)
In Week 4, you will complete the analysis and design for the project. You will use the guidelines described above and the grading rubric
below to complete this document. You will create the following items.
Request for new application
Problem analysis
List and description of the requirements
Interface storyboard or drawing
Design flowchart or pseudocode
The analysis and design document will be a single MS Word document, which contains all descriptions and drawings. See the grading
rubric below for the analysis and design document, due in Week 4.

User Manual (Due Week 7)
Your actual Course Project and user manual are due at the end of Week 7. However, it is strongly recommended that you start your
project in Week 5 to avoid many last minute issues.
In Week 7, you will be required to submit a user manual, as well as your Java code. The user manual can be a simple Word document with
screenshots that explains how to run your application. Your mark will depend both on the program quality and the quality of the user
manual.
Here are some more detailed guidelines about the user manual.
It does not need to be long, probably not more than 5 pages, including screenshots.
Write at the expected user’s level, not too technical.
Detail all the functionality that the application provides.

For each function, show what is its purpose and sample execution, with a screenshot.
