CS520 Module 2 Assignment

CS520 Module 2 Assignment
General Rules for Homework Assignments
 You are strongly encouraged to add comments throughout the program. Doing
so will help your facilitator to understand your programming logic and grade
you more accurately.
 You must work on your assignments individually. You are not allowed to copy
the answers from the others. However, you are encouraged to discuss
approaches to the homework assignment with your section mates and the
facilitator in your section via the discussion board.
 Each assignment has a strict deadline. However, you are still allowed to submit
your assignment within 2 days after the deadline with a penalty. 15% of the
credit will be deducted unless you made previous arrangements with your
facilitator and professor. Assignments submitted 2 days after the deadline will
not be graded.
 The assignment solution will be available 48 hours after the assignment
deadline.
 When the term lastName is referenced in an assignment, please replace it with
your last name.
You are strongly encouraged to add comments into your program!
Create a new Java Project in Eclipse named HW2_lastName and complete the
following two parts.
Part1 (50 Points)
Create a package named cs520.hw2.part1 and complete the following by writing the
appropriate classes under this package.
1. The course tuition is equal to the “credits for the course” multiplied by “the
cost per credit.” Create a “procedural style” program that meets the requirements
below. Create a class named TuitionProceduralStyle and test the tuition of two
different courses as specified below.
a.Prompt the user to enter the following values for the first course one by
one through a dialog box.
 The name of the first course, the number of credits for
the first course (integer type), and the cost per credit for
the first course (integer type)
b.Now, prompt the user to enter the following values for the second
course one by one through a dialog box.
 The name of the second course, the number of credits for
the second course (integer type), and the cost per credit for
the second course (integer type)
c. Compute the course tuition for the first course and store it into an
appropriate variable type.
d.Display the first course’s name and its tuition using a dialog box.
e.Compute the course tuition for the second course and store it into an
appropriate variable type.
f. Display the second course’s name and its tuition using a dialog box.
g.Using the if-else construct, check which tuition is greater than the other
and display the information and the difference using a dialog box. Also,
check if the tuitions are the same as part of this comparison.
h.Make sure to test your program with values for all the three scenarios
possible in the above step.
 2. Transform the procedural style computation of the previous problem into an
object-oriented application. In order to do this, create two classes named Course and
TuitionObjectStyle as specified below.
a.The class named Course describes each course and should have
 The instance (or member) variables – courseName (String),
costPerCredit (integer), and numberOfCredits (integer).
 The appropriate set methods for the above three variables.
 The appropriate get methods for the above three variables.
 The method getTotalTuition which returns the tuition for this
course.
 The method printTuitionDetails which displays the name
and the tuition of this course using a dialog box.
b.The class named TuitionObjectStyle creates two course objects and
tests them as follows:
 In the main method, instantiate two objects of the type Course
named course1 and course2.
 Perform the equivalent steps to the ones carried out in Step 1.
Part2 (50 Points)
Create a package named cs520.hw2.part2. Using this package, create the following
classes and implement the specified functionality.
1.Create a class named Course as follows.
a.The instance (or member) private variables – courseName (String),
costPerCredit (integer), and numberOfCredits (integer).
b.Only a single constructor with three arguments, the name, the cost per
credit, and the number of credits. Set the instance variables with the
specified argument values. Output to the console the values using the
get methods.
c. The public set and get methods for the three instance variables.
d.A public getTotalTuition method that returns the tuition for the course.
e.Override the toString method to return the string representation of this
object in the format “Course:<course name> @ $<total tuition>”.
2.Create a derived class from the Course class named OnlineCourse.
a. Only one private instance variable – technologyFee (integer) – is
allowed in the OnlineCourse class.
b.Only a single constructor with four arguments, the name, the cost per
credit, the number of credits, and the technology fee. Output to the
console the values using the get methods. The technology fee
specified is per credit for the online class.
c. The public set and get method for the technology fee only.
d.Override the getTotalTuition method which returns the sum of the
technology fee and the tuition as computed in the Course class. No
assumption should be made on how the tuition is computed by
the Course class.
e.Override the toString method to return the string representation of this
object in the format “OnlineCourse:<course name> @ $<total tuition>”.
3.Create a Test class to test the following functionality in its main method.
a. Declare a variable named currentCourse of type Course.
b. Create an Course object with appropriate values and assign it to the
above variable.
c. Print to the console the string representation of this object.
d. Create a OnlineCourse object with appropriate values. Reassign the
currentCourse to this object.
e. Print to the console the string representation of this object.
The sample output for Part2 is shown below.
Submission
Create an archive of your Eclipse project using the following steps. Select the
HW2_lastName project in the Eclipse IDE’s Package Explorer or the Navigator
window.
Click File->Export. Select the General->Archive File option. Click Next.
Specify the “To archive file:” entry as say, C:\Temp\HW2_lastName.zip.
The zip file will be created and stored in the C:\Temp folder.
Submit this zip file as an attachment in the Assignment Section.
