Plagiarism Notice
You are reminded that there exist regulations concerning plagiarism. Extracts from University Regulations on Cheating, Plagiarism and Collusion
Section 2.3: “The following broad types of offence can be identified and are provided as indicative examples …..
(i) Cheating: including 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 candidate’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 candidate’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:
(i) 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.
(ii) 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. ” e = 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.

Assessment
This assignment will be marked out of 100 and carries 30% of the overall module weighting.
Your .java files and report for this part must be uploaded and submitted by RTE Deadline.The assignment must be carried out individually so you must not obtain help from anyone other than the module teaching staff. You must not copy code from any source apart from the module core text and the module materials. Collusion, plagiarism (unreferenced copying), and other forms of cheating constitute Academic Misconduct, which can lead to failure of the module and suspension.
The viva will be conducted for this assignment.
Note:If a student would be unable to defend his/her coursework, s/he might be penalized with 50% of total coursework marks
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 teacher, together with its two subclasses to represent a Lecturerand a Tutor respectively. You will also need to write a report that should contain information about your program.
Deliverables
Create a new project in BlueJand create three new classes (Teacher, Lecturer,and Tutor) within the project. Lecturerand Tutorare subclassesof the class Teacher. When you are ready to submit your solution, upload your codes Teacher.java,Lecturer.java,andTutor.javafiles (not any other files from the project) together with your report in pdf format.

Program (56 marks)
The program should include the following classes (with no additional attributes or methods).
1) The Teacherclass has six attributes, which correspond to the teacher Id, teacher name, address, working type, employment status and working hours.The teacher name, address, working type, employment statusare each represented as a string of textand Teacher ID, and working hoursas a number.
The constructoraccepts five parameters which are, teacher Id, teacher name, address, working type, employment status.The attribute teacher nameis initialized with the parameter value. Additionally, assign teacher Id, address, working type, and employment statuswith the parameter values.
Each attribute has a corresponding accessor method.
A method is required to set the working hours. The method accepts a new working houras a parameter. The parameter value is then assigned to the attribute working hours.
A display method should output (suitably annotated) the teacher Id, teacher name, address, working type, and employment status. If the working hoursis not assigned, display a suitable message.
[10 marks]
2) The Lecturerclass is also a subclass of Teacherclass and it has four attributes:
Department– a String
YearsOfExperience– an integer
gradedScore– an integer
hasGraded– either true or false (boolean)
The constructoraccepts sevenparameters which are teacher Id, teacher name, address, working type, employment status, department and YearsOfExperience.A call is made to the superclass constructor with five parameters and a setter method. Also, assign, gradedScore as 0(zero)and
4
YearsOfExperiencewith the corresponding parameter values. In the constructor assign the attribute: hasGradedto false.
Each attribute has a corresponding accessor method.
Create a mutator methodfor attribute: gradedScore.
There is a method named gradeAssignment. The method is used to grade assignments of students who have submitted their assignments on time. The method accepts gradedScore, departmentand YearsOfExperience. If the yearsOfExperienceis higher than or equal to five years, and department is also relevant to the department with samearea of interest, then the lecturer will grade the assignments of students according to:
A —-> 70 and above
B —-> 60 and above
C—-> 50 and above
D—–> 40 and above
E—–> Less than 40
Now, the attribute hasGradedis set to true. If the lecturer has not graded yet, then a suitable message should be displayed.
A method to displaythe details of the Lectureis required. It must have the same signature as the display method in the Teacherclass. It will call the method in the Teacherclass to display the teacher Id, teacher name, address, working type, working hours, and employment status. It should also display a department, YearsOfExperience and gradedScore. If the score has notbeen graded yet, displaysuitable message. Each output must be suitably annotated.
[16 marks]
3) The Tutorclass is a subclassof Teacherclass and has five attributes:
salary– a double
specialization– a String
academic qualifications– a String
performanceIndex– an Integer
isCertified– a boolean
5
The constructor accepts ten parameters which are teacher Id, teacher name, address, working type, employment status, working hours, salary, specialization, academic qualificationsand performanceIndex.A call is made to the superclass constructorwith five parameters and a setter method. Additionally, in the constructor, assign salary, specialization, academic qualifications, performanceIndex with the parameter values. The attribute: isCertified is set to false.
Each attribute has a corresponding accessor method.
A method is required to setthe salary as each tutor can have different salaries. The method accepts a new salary, and new performanceIndexas a parameter and, if the performanceIndex is more than five(5) and the working hourof that tutor is greater than twenty(20), then calculate the salary as:
performanceIndex ———> appraisal
5-7 5%
8-9 10%
10 20%
[Note: new salary can be calculated as: salary + appraisal% of salary] Likewise, the status of isCertified is then set to trueafter appraisal. If the tutor has not been certified yet, then a suitable message is output to the user indicating that the salary cannot be approved.
There is a method named removeTutor.This method will remove the tutor (only if the tutor has not been certified yet). The attributes salary, specialization, academic qualifications and performance index is set to zero.The attribute isCertifiedis then set to false.
A method to displaythe details of the Tutorclass is required. It must have the same signature as the display method in the Teacherclass. If isCertifiedis set to false, It will call the method in the Teacherclass to display the details. However, if isCertifiedis set to true, salary, specialization, academic qualificationsand performanceIndexshould be displayed along with details of parent class.Each output must be suitably annotated.

Additional marks will be awarded for good programming styles, particularly naming, layout and comments.
See http://www.bluej.org/objects-first/styleguide.html for details. [12 marks]
Report (44 marks)
Your report should describe the process of development of your classes with: a. A class diagram [5 marks]b. Pseudocode for each class [10 marks]c. A short description of what each method does [5 marks]
d. You should give evidence (through inspection tables and appropriate screenshots) of the following testing that you carried out on your program: Test 1:Inspect the Lecturer class, grade the assignment, and re-inspect the Lecturer Class [3 marks]
Test 2:Inspect Tutor class, set salary and reinspect the Tutor class [4 marks]
Test 3:Inspect Tutor class again after removing the tutor.
[2 marks] Test 4:Display the details of Lecturer and Tutor classes.
[4 marks]
e. The report should contain a section on error detection and error correction where you give examples and evidence of three errors encountered in your implementation. The errors (syntax, semantic or logical errors) should be distinctive and not of the same type. [3 marks]
f. The report should contain a conclusion, where you need to include the following things:
▪ Evaluation of your work,
