PLAGIARISM

You are reminded that there exist regulations concerning plagiarism. Extracts from these regulations are printed overleaf. Please sign below to say that you have read and understand these extracts:

Extracts from University Regulations on Cheating, Plagiarism and Collusion

Section 2.3:โ€œThe following broad types of offence can be identified and are provided as indicative examples โ€ฆ.

(i) Cheating: including taking unauthorised material into an examination; consulting unauthorised material outside the examination hall during the examination; obtaining an unseen examination paper in advance of the examination; copying from another examinee; using an unauthorised calculator during the examination or storing unauthorised material in the memory of a programmable calculator which is taken into the examination; copying coursework.

(ii) Falsifying data in experimental results.

(iii) Personation, where a substitute takes an examination or test on behalf of the candidate. Both candidate and substitute may be guilty of an offence under these Regulations.

(iv) Bribery or attempted bribery of a person thought to have some influence on the candidateโ€™s assessment.

(v) Collusion to present joint work as the work solely of one individual. (vi) Plagiarism, where the work or ideas of another are presented as the candidateโ€™s own. (vii) Other conduct calculated to secure an advantage on assessment. (viii) Assisting in any of the above.

Some notes on what this means for students:

1. Copying another student’s work is an offence, whether from a copy on paper or from a computer file, and in whatever form the intellectual property being copied takes, including text, mathematical notation, and computer programs.

2. Taking extracts from published sources without attribution is an offence. To quote ideas, sometimes using extracts, is generally to be encouraged. Quoting ideas is achieved by stating an author’s argument and attributing it, perhaps by quoting, immediately in the text, his or her name and year of publication, e.g. โ€œe = mc2 (Einstein 1905)”. A reference section at the end of your work should then list all such references in alphabetical order of authors’ surnames. (There are variations on this referencing system which your tutors may prefer you to use.) If you wish to quote a paragraph or so from published work then indent the quotation on both left and right margins, using an italic font where practicable, and introduce the quotation with an attribution.

CONTRACT CHEATING

Contract cheating (also known as assessment outsourcing, commissioning or ghost writing) is when someone seeks out another party, or AI generator service, to produce work or buy an essay or assignment, either already written or specifically written for them or the assignment to submit as their own piece of work.

Contract cheating undermines the integrity of the academic process and devalues the qualifications awarded by the university. Students are reminded that academic integrity is a fundamental principle of our institution. Engaging in contract cheating not only impacts the individualโ€™s academic record but also the reputation of the university.

Students are encouraged to seek support if they are struggling with their coursework. The university offers a range of resources, including academic counseling, tutoring services, and workshops on study skills and time management. Utilizing these resources can help students achieve their academic goals without resorting to dishonest practices.

Penalty:

โ— Failure in the Module: The student must re-register for the same module, and the re-registered module will be capped at a bare pass.

โ— Ineligibility to Continue on the Course: Where re-registration of the same module, or a suitable alternative, is not permissible, the student will not be able to continue on the course. Additionally, the following penalty will be applied to the studentโ€™s final award:

o Undergraduate Honors: The studentโ€™s final classification will be reduced by one level.

o Unclassified Bachelors: Downgraded to Diploma in Higher Education. o Foundation Degree: Distinction downgraded to Merit; Merit downgraded to Pass; Pass downgraded to Certificate in Higher Education.

o Masters: Distinction downgraded to Merit; Merit downgraded to Pass; Pass downgraded to Postgraduate Diploma.

Reporting and Consequences:

Instances of contract cheating will be thoroughly investigated, and students found guilty will face the penalties outlined above. It is the responsibility of every student to ensure that their work is their own and to avoid situations that could lead to accusations of academic misconduct.

By adhering to these standards, students contribute to a fair and equitable academic environment, ensuring the value and recognition of their qualifications are maintained.

Aim

The aim of this assignment is to implement a real-world problem scenario using the Object-oriented concept of Java that includes creating a class to represent a GymMember, together with its two subclasses to represent RegularMember and PremiumMember respectively.

GUI part of coursework focuses on expanding the project by integrating a new class to implement a graphical user interface (GUI). The goal is to create a system that stores Gym Member details within an ArrayList. This class will contain the main method and will be executed via the command prompt. Additionally, you are required to submit a report explaining the functionality and structure of your program.

Deliverables

Create a new project in BlueJ and create three new classes (GymMember, RegularMember and PremiumMember) within the project. RegularMember and PremiumMember are subclasses of the class GymMember.

For the GUI implementation part, add a new class to your project named GymGUI. Once your solution is complete, submit the GymGUI.java file along with the GymMember.java, RegularMember.java, and PremiumMember.java files. Ensure that no other files from the project are included. Additionally, submit your report in PDF format.

Scenario

You are developing a system to manage members of a gym that offers different membership plans and tracks attendance and loyalty points. Each member is identified by a unique ID and has personal details such as their name, location, phone number, email, membership start date, and membership plan. You have to keep track of how often members visit the gym (attendance) and their accumulated loyalty points.

NOTE: – The program should include following classes (with no additional attributes or methods).

4

Program (55 marks)

1. Parent Class: GymMember [5 marks]

The GymMember is a parent class as abstract class which has following attributes with their respective data type and with protected access modifier as mentioned below:

id – int

name – String location: String phone – String email โ€“ String gender โ€“ String

DOB – String

membershipStartDate – String attendance – int

loyaltyPoints – double

activeStatus โ€“ boolean

The constructor of this class accepts id, name, location, phone, email, gender, DOB, and membershipStartDate as parameters. The attributes attendance and loyaltyPoints are initialized to zero and activeStatus is set to false. Additionally, assign id, name, location, phone, email, membershipStartDate, plan and price with the parameter values.

Each attribute has a corresponding accessor method.

An abstract method markAttendance() is created to track attendance of the member.

A method activateMembership() sets activeStatus to true when the membership needs to be activated or renewed and a method deactivateMembership() sets the activeStatus to false if the membership needs to be deactivated or paused.

[Note: The membership must be activated first in order to deactivate. Also, the membership is deactivated by default]

Also, method resetMember() is created to set activeStatus of the member to false, attendance is set to zero and loyaltyPoints to zero.

A display method should output (suitably annotated) the id, name, location, phone, email, gender, DOB, membershipStartDate, attendance, loyaltyPoints and activeStatus.

5

2. Subclass: RegularMember [10 marks]

The RegularMember class is a subclass of GymMember class, and it has six private attributes with following data types:

attendanceLimit – int (final)

isEligibleForUpgrade – boolean

removalReason – String

referralSource – String

plan – String

price – double

The constructor accepts nine parameters which are id, name, location, phone, email, gender, DOB, membershipStartDate and referralSource. A call is made to the superclass constructor with eight parameters. The attribute isEligibleForUpgrade is set to false, attendanceLimit is set to 30, plan is set to basic, price is set to 6500 and removalReason is set to empty. Also, assign other attributes with corresponding parameter values.

Each attribute of RegularMember class has a corresponding accessor method.

Implement the abstract method markAttendance() to increment the attendance value by 1 each time this method is invoked. Also, the loyaltyPoints should be increased by 5 points.

There is a method named getPlanPrice() with return type double to retrieve the price of the provided plan. This method accepts plan as a parameter and returns its corresponding price. The following are the pricings of available gym plans:

basic 6500

standard 12500

deluxe 18500

The switch statement must be implemented for this specific scenario to return the corresponding planโ€™s price.

6

[Note: if the invalid plan is passed as an argument then the getPlanPrice() method should return -1]

There is a method upgradePlan() with return type String. This method is used to upgrade the plan subscribed by the member. The method accepts plan as a parameter. If the member is eligible for upgrading the plan, then the plan and price should be updated accordingly by calling getPlanPrice() method.

Also, the system should validate and display appropriate message if same plan is chosen that the member is currently subscribed to.

Note: If getAttendance() >= attendanceLimit then set isEligibleForUpgrade to true

[Hint: if the method getPlanPrice() returns -1 then an appropriate message should be displayed. The upgradePlan() method should return the appropriate message as the return type of the method is String]

Now, create revertRegularMember() method which accepts removalReason as a parameter. A super class method: resetMember() is called here and isEligibleForUpgrade set to false, plan is set to basic and price is set to 6500. Also, assign other attributes with corresponding parameter values.

A method to display the details of the RegularMember is required. It must have the same signature as the display method in the parent class. It will call the method in the super class to display all the attributes of super class. Also, display the value of attributes: plan and price. Additionally, display removalReason if its value is not empty.

7

3. Subclass: PremiumMember [10 marks]

The PremiumMember class is a subclass of GymMember class, and it has three attributes:

premiumCharge – double(final)

personalTrainer – String

isFullPayment – boolean

paidAmount – double

discountAmount – double

The constructor accepts nine parameters which are id, name, location, phone, email, gender, DOB, membershipStartDate, and personalTrainer. A call is made to the superclass constructor with eight parameters. The attribute premiumCharge is set to 50,000, paidAmount is set to 0 and isFullPayment is set to false, and discountAmount is set to zero. Also, assign other attributes with corresponding parameter values.

Each attribute of PremiumMember class has a corresponding accessor method. Here, a method payDueAmount() of return type String is created to pay the due amount. It accepts paidAmount as a parameter. Received paidAmount from the parameter should be added on paidAmount attribute.

Following validations should be made inside this method:-

โ— if payment is already full (this.isFullPayment == true),a suitable message should be displayed and returned.

โ— if the total paid amount is more than premiumCharge, a suitable message should be displayed and returned.

Now, If the payment is successful, a suitable message should be displayed and returned including the remainingAmount to be paid. The value of isFullPayment will also be updated accordingly.

[remainingAmount = premiumCharge โ€“ this.paidAmount]

[Hint: if the total paidAmount is equal to the premiumCharge, then isFullPayment should be set to true otherwise false.]

8

There is a method named calculateDiscount(). This method is used to calculate discount amounts based on payment status. If the payment is full then the premium member will get a 10% discount on the premium planโ€™s charge, otherwise there would not be any discount. Here, if the discount is calculated successfully, the value of the discountAmount attribute will be updated and a suitable message will be displayed.

[Note: If isFullPayment == true then discountAmount = 10% of planโ€™s price]

Create a method name revertPremiumMember() which calls the super class resetMember() method. Additionally, the value of personalTrainer is set to empty, isFullPayment is set to false, and paidAmount, and discountAmount are set to zero.

A method is required to display the details of the PremiumMember and it must have the same signature as the display method in the parent class. It will call the method in the super class to display all the attributes of super class. Additionally, it should display the value of personalTrainer, paidAmount and isFullPayment. Also, the remaining amount to be paid should be calculated and displayed with suitable annotation. Also, discountAmount will only be displayed, if the payment is done completely.

[ Hint: remainingAmount = premiumCharge โ€“ this.paidAmount ]

9

GUI Implementation โ€“ Part [25 Marks]

Your GUI should include the same components, but you have the flexibility to choose a different layout if it enhances aesthetics or usability. The GymGUI class must maintain an ArrayList (not a simple array) of the GymMember class, which will hold both RegularMember and PremiumMember objects.

[Note: Only one ArrayList should be created.]

There should be following text fields for entering:

1. Id

2. Name

3. Location

4. Phone

5. Email

6. Gender

7. DOB

8. Membership Start Date

9. Referral Source

10. Paid Amount

11. Removal Reason

12. Trainerโ€™s Name

Also, there should be a non-editable text field for regular plan price, premium plan charge and discount amount.

The gender should be displayed as a radio button.

The Plan (Basic, Standard, Deluxe) attribute should be displayed as a JComboBox for plan selection for regular members only.

10

The GUI should have the following buttons to perform specific task:

1. Add a Regular Member

When this button is pressed, the input values from the text fields (ID, Name, Location, Phone, Email, Gender, DOB, Membership Start Date,Referral Source) will be used to create a RegularMember object. This object will then be added to an ArrayList of the GymMember class.

Note: Member ID duplication is prohibited. Each member, whether Regular or Premium, must have a unique Member ID]

2. Add a Premium Member

When this button is pressed, the input values from the text fields (ID, Name, Location, Phone, Email, Gender, DOB, Membership Start Date, Personal Trainer) will be used to create an object of Premium member and this object will then be added to an ArrayList of the GymMember class.

11

[Note: Member ID duplication is prohibited. Each member, whether Regular or Premium, must have a unique Member ID.]

3. Activate Membership

The Member Id should be entered in the GUI to activate membership. When this button is pressed, the input value of Member Id is compared to the existing Member Id. If the entered Member Id is valid and exists in the system, then call the method to activate membership from GymMember class.

4. Deactivate Membership

The Member Id should be entered in the GUI to deactivate membership. When this button is pressed, the input value of Member Id is compared to the existing Member Id. If the entered Member Id is valid and exists in the system, then call the method to deactivate membership from GymMember class.

12

5. Mark Attendance

First, the Member Id should be entered in the GUI to mark attendance. When this button is pressed, the input value of Member Id is compared to the existing Member Id. If the entered Member Id is valid and exists in the system, then call the method to mark attendance from GymMember class.

[Note: if only active status of member is true, proceed with mark attendance] 6. Upgrade Plan

The Member Id is entered, and the required Plan selected in the GUI. When this button is pressed, the input value of Member Id is compared to the existing Member Id. If the entered Member Id is valid and exists in the system, then call the method to upgrade plan from RegularMember class. Upgrading the plan is only possible if the member is active.

[Hint: An object of GymMember is cast as RegularMember.]

7. Calculate Discount

To calculate a discount, the Member Id is entered. When this button is pressed, the input value of Member Id is compared to the existing Member Id. If the entered Member Id is valid and exists in the system, then call the method to calculate discount from PremiumMember class.

[Hint: An object of GymMember is cast as RegularMember.]

8. Revert Member

To remove a member, the MemberID is entered in the GUI. When this button is pressed the, the input value of Member Id is compared to the existing Member Id. If the entered Member Id is valid and exists in the system and then call the method to revert member from both RegularMember and PremiumMember class.

[Note: there should be two separate buttons for reverting the members of each class]

13

9. Pay Due amount

To pay the due amount, the MemberID , and amount to be paid is entered in the GUI. When this button is pressed, the input value of Member Id is compared to the existing Member Id. If the entered Member Id is valid and exists in the system and then call the method to pay the due amount of the Premium gym member.

10.Display

When this button is pressed, the information of all the members of the respective class should be displayed in a separate frame/panel in the GUI.

11. Clear

When this button is pressed the entered values from text fields should be cleared and the check box should be unchecked.

12.Save to File

When this button is pressed all the member details stored in the arraylist should be written to file named โ€œMemberDetails.txtโ€ as shown in the figure below:

[Hint:- You can use this string format as reference and adjust accordingly: String.format(“%-5s %-15s %-15s %-15s %-25s %-20s %-10s %-10s %-10s %- 15s %-10s %-15s %-15s %-15s\n”, “ID”, “Name”, “Location”, “Phone”, “Email”, “Membership Start Date”, “Plan”, “Price”, “Attendance”, “Loyalty Points”, “Active Status”, “Full Payment”, “Discount Amount”, “Net Amount Paid”); ]

13.Read from File

When this button is pressed all the member details written in a text file should be read and displayed in separate frame/panel in an organized format.

14

Additional Information to be included:

โ— Retrieve the values from each text field by using the getText() method.

โ— For numeric variables, extract the text from the text field, convert it to an integer, and return the result as a whole number.

โ— Use try and catch blocks to handle potential NumberFomatException with that may occur during the conversion of the string to an integer or double.

โ— In case of successful operations, display an appropriate success message to the user using a message dialog box.

โ— In case of incorrect input, display an appropriate error message to the user using a message dialog box.
