Project Description
Your team will continue to work on the next phase of the software developed in Project 1. The fitness chain provides
3 membership options – standard, family, and premium. The software shall run the membership fee dues for all the
members. The membership fees are listed in the table below.
Membership
Type One-Time Fee Fee Schedule Fitness Classes check-in
Standard
$29.99
$39.99, per month
pay quarterly Membership location only
Family $59.99 per month,
pay quarterly
• Any location
• 1 family guest pass, membership
location only
Premium waived
One month free of Family
membership rate,
pay annually
• Same as Family, and
• 3 family guest passes, membership
location only
The three different fitness classes, Pilates, Spinning and Cardio, are now offered in person at different gym locations.
Members are required to check in before they participate in the classes. To accommodate the increase of memberships,
the fitness chain is adding more fitness classes and hiring additional instructors. However, members with the standard
membership can participate in the classes held at the membership location only. Members with family and premium
memberships can participate in the classes held at any locations. Family guest passes can only be used for the fitness
classes held at the membership location.
There are currently 5 instructors teaching the classes, Jennifer, Kim, Denise, Davis and Emma. The fitness chain will
provide the class schedule in a text file. This allows the change of schedule independent to the software and loading
of the schedule to the database in batch. Currently, fitness classes are regularly offered during a day in the morning,
afternoon, and evening, at 9:30, 14:00 and 18:30, respectively. Each fitness class can be uniquely identified by the

class name, instructor, and location. The software shall load the class schedule from an external text file to the system
so the members can check in for the classes.
To run the fees, additional information is needed at the time of adding the members to the database. In addition to
keeping the functionalities implemented in Project 1, you will make the changes to add or change the relevant
commands to accommodate the new requirements in this project. The commands R, P, PD, PC, PD, S should work
the same way as in Project 1. New commands or the commands that need to be changed are listed below.
• LS command, a new command to load the fitness class schedule from the file classSchedule.txt to the class
schedule in the software system.
• LM command. There is historical member information needed to be imported to the database. This is a new
command to load a list of members from the file memberList.txt to the member database.
• A command, to add a member with the standard membership to the member database. The expiration date should
set to expire 3 months later. NOTE: the expiration date will be based on the date you add the member. The
expiration dates in the file Project2_expectedOutput.txt I provided are based on the date I generated the output.
The expiration dates you generated should be different.
• AF command, to add a member with the family membership to the member database. The expiration date should
set to expire 3 months later. NOTE: see the NOTE above.
• AP command, to add a member with the premium membership to the member database. The expiration date should
set to expire one year later.
• PF command, a new command to print the list of members with the membership fees. Let’s assume the
membership fees are for the next billing statement, regardless of the current membership expiration dates.
• C command, members check-in for a fitness class.
• CG command, family guest check-in for a fitness class; must keep track of the remaining number of guest passes.
• D command, a member is done with a fitness class and checking out.
• DG command, a guest is done with a fitness class, and checking out; must keep track of the remaining number of
guest passes.
Project Requirement
1. You MUST follow the Coding Standard and Ground Rules posted on Canvas under Week #1 in the “Modules”.
You will lose points if you are not following the rules.
2. You are responsible for following the Academic Integrity Policy. See the Additional Note #13 in the syllabus.
3. You must preserve all the functionalities developed in Project 1 to pass the test cases. There are test cases in the
file Project2_testCases.txt for you to test the project. The associated output is in Project2_expectedOutput.txt.
The graders will be using the sample test cases to test your project. Your project should be able to take the test
cases from the console in the same order line by line without getting any exceptions and without terminating
abnormally, including the empty lines. You will lose 2 points for each incorrect output or each exception causing
the project to terminate abnormally.
4. Each Java class must go in a separate file. -2 points if you put more than one Java class into a file.
5. Your program MUST handle bad commands; -2 points for each bad command not handled, with a maximum of
losing 6 points.
6. You are not allowed to import any Java library classes, EXCEPT the Scanner, File, StringTokenizer, Calendar,
DecimalForamt, and necessary Java Exception classes. You will lose 5 points for each additional Java library
class imported, with a maximum of losing 10 points.

7. You CAN use the Java library class ArrayList in the FitnessClass class for this project. You CANNOT use
ArrayList in any other classes. You CANNOT use any other classes in the Java Collections. You will get 0 points
for this project for any of the violations above.
8. When you import Java library classes, be specific and DO NOT import unnecessary classes or import the whole
package. For example, import java.util.*;, this will import all classes in the java.util package. You will
lose 2 points for using the asterisk “*” to include all the Java classes in the java.util package, or other java
packages, with a maximum of losing 4 points.
9. You MUST create a Class Diagram for this project to document the software structure. The diagram is worth 10
points. You will lose the 10 points if you submit a hand-drawing diagram.
10. You are not allowed to have redundant code in this project; reuse the code as much as possible by using the
super keyword, -2 point for each violation, and -2 points for each violation below.
• Unused code: you write code that was never called or used.
• Duplicate code segments for the same purpose in more than one places/classes.
• Define common instance variables in each of the subclasses while they should be defined in the superclass.
• Define specific instance variables in the superclass while they are not used by all the subclasses.
• Define common methods in each subclass instead of defining it in the superclass.
• Not defining instance variables as private.
11. You must define classes with the following inheritance relationships. -5 pointsfor each class missing, or incorrect
inheritance structure.
• Member class from Project 1 defines the standard membership and the common instance variables and
instance methods of the subclasses Family and Premium. You must include the following method or lose
3 points. You CANNOT change or add additional instance variables, or -2 points for each violation.
public double membershipFee() { }
• Family class extends the Member class and includes specific data and operations to a family membership;
you must override the membershipFee() method, or lose 3 points.
• Premium class extends the Family class and includes specific data and operations to a premium
membership; you must override the membershipFee() method, or lose 3 points. You may need to override
other public methods defined in Family class.
12. Polymorphism is required. You CANNOT use the getClass() method for checking the class type listed in #11
above, or you will lose 10 points. You can use instanceof keyword to check the actual type of an object. Common
instance variables and public methods must be defined in the superclass. Override the public methods in the
superclass if necessary. If you are overriding any methods, you must add the annotation @Override on top of
the methods. -2 points for each violation.
13. In addition to the classes in #11, you must add or modify the classes listed below. -5 points for each class missing.
You CANNOT perform I/O in all classes, EXCEPT the GymManager class, and the print methods in the
