Project Description
A fitness club owns the studios at 5 different locations in the central New Jersey area as listed below.
Bridgewater, 08807, Somerset County
Edison, 08837, Middlesex County
Franklin, 08873, Somerset County
Piscataway, 08854, Middlesex County
Somerville, 08876, Somerset County
Your team will develop a software to help the fitness club manages the memberships and class schedules. The
software is an interactive system where the users enter the command lines on the terminal and the system displays
the information on the terminal after the users hit the enter key. A command line specifies the operation the user
wanted to perform and includes the data tokens required to complete the operation. An operation code is a single
character or two-character command in uppercase letters. The operation code and the data tokens will be delimited
by one or more spaces in a command line. Operation codes are case-sensitive, which means operation codes with
lowercase letters should be rejected by the system. The software shall provide the functionality of adding and
removing members, managing the attendance of the fitness classes, generating the billing statements, and displaying
membership information in a specified order.
The fitness club currently offers 3 membership options – basic, family, and premium. Members must be 18 or older
to join. There are 3 types of fitness classes, Pilates, Spinning and Cardio, being offered at different studio locations.
Members with the basic membership can only attend the classes offered at the home studio. Members with family
and premium memberships can attend the classes offered at any studio location. Anyone holding a guest pass can
only attend the fitness classes held at the home studio. The software shall run the membership fee dues for all the
members. The fee schedules are listed in the table below.

Membership Type Fee Schedule Fitness Class Attendance
Basic
 $39.99, per month
 billed monthly
 additional charge of $10 per
class exceeding 4 classes
 home studio only
 no guest pass
 4 classes per billing cycle
Family  $49.99 per month,
 billed quarterly (3 months)
 Any studio location for the member
 Home studio only for the guests
 1 guest pass at anytime
Premium
 $59.99 per month
 billed annually with one month
free (pay 11 months)
 Any studio location for the member
 Home studio only for the guests
 3 guest passes at anytime
There are 5 instructors teaching the classes, including Jennifer, Kim, Denise, Davis, and Emma. The fitness club will
provide the class schedule in a text file. This allows the change of schedule independent to the software. Currently,
fitness classes are regularly offered every 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 studio location. The
system shall load the class schedule from a text file classSchedule.txt and load the historical member information
from the text file memberList.txt. The system shall support the following operation codes (commands.)
 When adding a new member, the system shall create a profile for a new member with the first name, last name,
and date of birth. The profile can be used to uniquely identify the member. There are 3 different add commands.
o AB, to add a member with Basic membership, followed by member’s first and last name, date of birth, and the
location (in city name) of the home studio. Below is a sample command line for adding a member with a Basic
membership. The system shall set the expiration date to 1 month later, e.g., if today is 3/31, the expiration date
is 4/30, the last day of next month. The expiration date depends on the date when you are adding the member.
AB April March 3/31/1990 Piscataway
The date is given in a mm/dd/yyyy format. The names and locations are NOT case-sensitive, that is, April
March and april march are the same person if the dates of birth are also the same; PISCATAWAY and
Piscataway represent the same location. Your software shall not add the member to the database if the data
tokens in the command line have the following conditions.
1. Any date that is not a valid calendar date.
2. The date of birth is today or a future date.
3. A member being added is less than 18 years old. Note, the system checks the birthday month only, e.g., if
today is 2/6/2024, dob 2/28/2006 is considered as eligible, but dob 3/1/2006 is not eligible.
4. An invalid city name has been entered, that is, the studio location doesn’t exist.
5. The member is already in the member database.
6. Not enough data tokens to complete the operation.
o AF, to add a member with Family membership to the member database. Check all conditions listed above. The
expiration date should be set to expire 3 months later.
o AP, to add a member with Premium membership to the member database. Check all conditions listed above.
The expiration date should be set to expire one year later.
 C, to cancel the membership and remove the member from the member database. Since the system checks the
date of birth when adding a member, it doesn’t check the dob when removing a member. However, the member
being removed may not exist in the database. Sample command line: C Paul Siegel 5/1/1999

 S, display the class schedule with the current attendees. Each fitness class shall include the class name, instructor’s
name, the time of the class, and the list of members/guests who have registered. For simplicity, we abstract away
the complexity of tracking the dates of the class schedule. That is, the system does not maintain the dates of the
class schedule, only shows the “current” class schedule.
 Printing the list of members in the member database.
o PM, to display the members sorted by member profiles, i.e., last names, then first names, then dates of birth.
o PC, to display the members sorted by county names, then zip codes.
o PF, to print the members with the membership fees. For simplicity, assume the membership fees are for the
next billing statement, regardless of the membership expiration dates.
 R, to take attendance of a member attending a class and add the member to the class, including the class name,
instructor, and member profile, for example:
R cardio Jennifer somerville Roy Brooks 12/8/1977
The system shall not add the member if the following conditions exist. Check in the order of the data tokens.
o The class name does not exist.
o The instructor does not exist.
o The studio location does not exist.
o The member is not in the member database.
o The membership expired.
o The fitness class in not on the class schedule.
o Member with Basic membership can only attend the classes held at the home studio.
o Time conflict – member is currently in a class held at the same time.
o Member is already added to the class schedule.
 U command, to remove a member from a class, for example, U Pilates Mary Lindsey 12/1/1989
Since the system checks the conditions when adding the member, it shall only check if the member is in the class
to remove.
 RG, to take attendance of a guest attending a class and add the guest to the class. The system does not maintain
guest information. Therefore, the system checks all the conditions in the R command, EXCEPT time conflict. In
addition, the system checks the restrictions of the associated membership, including the home studio location and
the number of guest passes allowed. Below is a sample command line to add a guest of Jonnathan Wei to a class.
RG cardio Davis bridgewater Jonnathan Wei 9/21/1992
 UG, to remove the guest from a class: UG pilates davis Edison Jerry Brown 6/30/1979.
The system shall not remove the guest if the guest is not in the class, or the fitness class does not exist.
 Q, to stop the program execution and display "Studio Manager terminated.", so the user knows that
your software has stopped running normally.
Project Requirement
1. You MUST follow the Coding Standard posted on Canvas under Week #1 in the “Modules”. You will lose points
if you are not following the rules.
2. You are required to follow the Academic Integrity Policy. See the Additional Note #14 in the syllabus. If your
team uses a repository hosted on a public website, you MUST set the repository to private. Setting it to public is
considered as violating the academic integrity policy. The consequences of violation of Academic Integrity Policy
are: (i) your group receives 0 (zero) on the project, (ii) the violation is reported, (iii) a record on your file
of this violation.

3. Test cases for grading are included in the file Project2TestCases.txt and the associated output is in the file
Project2ExpectedOutput.txt. Your project should be able to read the test cases from console in the same order
with the test cases provided in Project2TestCases.txt, line by line without getting any exceptions. Your program
should be able to ignore the empty lines. The graders will run your project with the test cases in
Project2TestCases.txt and compare your output with the expected output in Project2ExpectedOutput.txt. Note
that, the expiration dates in Project2ExpectedOutput.txt were generated on the day I ran the project. The
expiration dates you generated should be different. The data used this project are not associated with any realworld entity and they are created solely for testing purpose.
4. You will lose 2 points for each output not matching the expected output, OR for each exception causing your
project to terminate abnormally. You MUST use the Scanner class to read the command lines from the standard
input (System.in), DO NOT read from an external file, except memberList.txt and classSchedule.txt, or you
will lose 5 points.
5. Each source file (.java file) can only include one public Java class, and the file name is the same with the Java
class name, or you will lose -2 points.
6. Your program MUST handle bad commands; -2 points for each bad command not handled, with a maximum of
losing 6 points.
7. You are NOT allowed to import any Java library classes, EXCEPT the Scanner, File, StringTokenizer,
Calendar, DecimalForamt, and Java Exception classes. You will lose 5 points for each additional Java library
class imported, with a maximum of losing 10 points.
8. You are NOT allowed to use the Java library class ArrayList anywhere in the project OR use any Java library
classes from the Java Collections, or you will get 0 points for this project!
9. 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.
10. You must define the classes below with the specified inheritance relationships. -5 points for each class missing,
or incorrect inheritance structure.
 Member class defines the common instance variables and instance methods of the subclasses. See the
details of this class in the requirement #12 below.
 Basic class extends the Member class and includes the instance variable private int numClasses;
to keep track of the number of classes attended so far; must override the bill() method, or lose 3 points.
 Family class extends the Member class and includes the instance variable private boolean guest;
to keep track of the guest pass; must override the bill() method, or lose 3 points.
 Premium class extends the Member class and includes the instance variable private int guestPass;
to keep track of the guest passes; must override the bill() method, or lose 3 points.
11. Polymorphism is required, i.e., dynamic binding for the equals(), compareTo(), toString(), and the bill() method
or you will lose 10 points.
12. In addition to the classes in #10, you are required to include the Java classes below, or -5 points for each class
missing. You must always add the @Override tag for overriding methods, or -2 points for each violation. All
instance variables must be “private”. You cannot add additional instance variables or change the method

(a) Member class.
 public class Member implements Comparable<Member> {
 private Profile profile;
 private Date expire;
 private Location homeStudio;
public double bill() { } //return the next due amount
 }
 Location is a Enum class defining the studio locations listed in Page #1 of this document.
 Reuse the Date class in Project 1.
 Profile class must be defined as follows. Must override equals(), toString() and compareTo() methods,
cannot add or change the instance variables, or -2 points each.
public class Profile implements Comparable<Profile>{
 private String fname;
 private String lname;
 private Date dob;
 }
 You must implement compareTo() method and override equals() and toString() method -2 points for
each violation. The toString() method returns a textual representation of a member in the following format.
Jane:Doe:5/1/1996, Membership expires 6/2/2024, Location: EDISON, 08837, MIDDLESEX
(b) MemberList class. This is an array-based implementation of a linear data structure to hold a list of member
objects. An instance of this class is a growable list with an initial array capacity of 4, and it automatically
increases the capacity by 4 whenever it is full. The list does not decrease in capacity. An instance of this
class can hold a list of members with different types of membership.
 public class MemberList {
 private Member [] members; //holds Basic, Family, or Premium objects
 private int size; //number of objects in the array
 private int find(Member member) { }
 private void grow() { }
 public boolean contains(Member member) { }
 public boolean add(Member member) { } //add to end of array
 public boolean remove(Member member) { } //shift up to remove
 public void load(File file) throws IOException { }//from the text file
 public void printByCounty() { } //sort by county then zip code
 public void printByMember() { } //sort by member profile
 public void printFees() //print the array as is with the next due amounts
}
 You must implement the methods listed above, and you CANNOT change the signatures of the methods.
-2 points for each method not implemented, signature changed or not used.
 The find() method searches a member in the list and returns the index if it is found, it returns -1 if the
member is not in the list. You must define a constant identifier “NOT_FOUND” for the value -1.
 The remove() method remove a member from the list. This method maintains the relative order of the
members in the list after the remove, -3 points if this is not done correctly.
 You must use an in-place sorting algorithm to rearrange the order of member objects in the array. That
is, no additional array can be declared for sorting, or you will lose 10 points. You must write code to
implement the algorithm. You CANNOT use Arrays.sort() or System.arraycopy() or any other Java
library classes for sorting. You will lose 10 points if you do.

 load() method loads the list of members from a text file.
(c) Schedule class. An instance of this class holds a list of fitness classes loaded from the text file
classSchedule.txt. You cannot add or change the instance variables, and must implement the load()
method or -2 points each violation. You can add constructors and methods.
public class Schedule {
 private FitnessClass [] classes;
 private int numClasses;
 public void load(File file) throws IOException { }
}
(d) FitnessClass class. An instance of this class holds the information of a fitness class and the attendees for
members and guests. You cannot add or change the instance variables, or -2 points each.
public class FitnessClass {
 private Offer classInfo;
 private Instructor instructor;
 private Location studio;
 private Time time;
 private MemberList members;
 private MemberList guests;
}
 Offer is a Enum class to include 3 types of fitness classes: Pilates, Spinning, and Cardio.
 Instructor is a Enum class to include the 5 instructors.
 Time is a Enum class. You cannot add change the constant values, or -2 points each.
public enum Time {
 MORNING (9, 30),
 AFTERNOON (14, 0),
 EVENING (18, 30);
}
(e) StudioManager class
 This is the user interface class to process the command lines. An instance of this class can process a single
command line or multiple command lines at a time. You will lose 10 points if it cannot process multiple
command lines at a time.
 This class should handle all possible Java exceptions thrown by the backend classes, or -5 points each
violation for handling the exceptions in the backend classes.
 When your project starts running, it shall load the 2 text files first, and then display "Studio Manager
is up running...”. so, the user knows the software is ready to read the command lines. It should
continuously process the command lines until the “Q” command is entered. The system displays "Studio
Manager terminated." and then terminates the project execution.
 You must define a public void run() method to process the command lines. You will lose 5 points
if the run() method is missing. You MUST keep this method under 40 lines for readability, or you will
lose 3 points.
(f) RunProject2 class is a driver class to run your Project 2. The main method will call the run() method in
the StudioManager class.
public class RunProject2 {
 public static void main(String[] args) {
 new StudioManager().run(); }
}

you have in the testbed main() from Project 1.
 MemberList class
o add() method – 3 true cases and 3 false cases for adding Basic, Family and Premium.
o remove() method – 1 true case and 1 false case for removing a random member.
14. Class Diagram. Create a class diagram to document your software structure for Project 2. Hand-drawing the
diagram is not acceptable, and you’ll lose 10 points. You can follow the links below to create a class diagram
online and save it to your device as a picture, which can be included in your submission. You can also use other
UML tools if you like. For each rectangle (class), include ONLY the instance variables and public methods. NO
need to include the constants and private methods. DO NOT INCLUDE the JUnit test classes, the Java library
classes and RunProject2 class in the diagram.
