A. A first name (given name) B. A last name (family name/surname) C. Student number (ID) - an integer number (of typelong) The Student class will haveat leastthe following constructors and methods:

The Student class will have at least the following constructors and methods:

(i) two constructors - one without any parameters (the default constructor), and one with

parameters to give initial values to all the instance variables of Student.

(ii) only necessary set and get methods for a valid class design.

(iii) a report grade method, in which you have nothing to report here, you can just print to the screen

a message "There is no grade here.". This method will be overridden in the respective child

classes.

(iv) an equal's method that compares two student objects and returns true if they have the same

student number (ID), otherwise it returns false.

You may add other methods in the Student class as you see appropriate, however, you will need to justify why those methods are required. Design, code in Java, test and document (at least) the following classes - a Student_Course class, a Student_Research class (both derived from the Student class) a Unit_Course class, Research class (both derived from the Unit class specified below) and a Client class. Assuming in this program, you allow multiple student objects to be created (i.e. arraylist of student objects).

For course work students (Student_Course class): (a) Contain enrolment type. (b) Provide a reportGrade method such that it will output "C" (to identify as course work student), the Name (first name and last name), student number, the unit ID, the overall mark, and the final grade of the student. For research students (Student_Research class): (a) Contain enrolment type. (b) Provide a reportGrade method such that it will output "R" (to identify as research student), the Name (first name and last name), student number, the overall mark, and the final grade of the student. Unit class: (a) Enrolment type: "C" for course work enrolment and "R" for research enrolment. (b) A final grade reporting method for reporting the "NA" for not available. Course work unit (Unit_Course class): (a) Will have the information of the unit ID (of type string; e.g. ICT333), and the level of the unit (of type integer; e.g. 3 for third year) (b) There are two assignments, each marked out of a maximum of 100 marks and equally weighted. The marks for each assignment are recorded separately. (c) There is one final examination that is marked out of a maximum of 100 marks and recorded separately. (d) An overall mark (to be calculated within the class) (e) A final grade, which is a string (avoid code duplication for calculating this) The final grade is to be awarded on the basis of an overall mark, which is a number in the range 0 to 100 and is obtained by calculating the weighted average of the student's performance in the assessment components. The criteria for calculating the weighted average is as defined below: The two assignments together count for a total of 60% (30% each) of the final grade, and the final exam is worth 40% of the final grade. A grade is to be awarded for the students as follows: An overall mark of 80 or higher is an HD, an overall mark of 70 or higher (but less than 80) is a D, an overall mark of 60 or higher (but less than 70) is a C, an overall mark of 50 or higher (but less than 60) is a P, and an overall mark below 50 is an N. Research enrolment (Research class): (a) Enrolment type as "R" (b) There is a proposal, marked out of a maximum of 100 mark. (c) There is a final dissertation, marked out of a maximum of 100 mark. (d) An overall mark (to be calculated within the class) (e) A final grade, which is a string (avoid code duplication for calculating this)

The final grade is to be awarded on the basis of an overall mark, which is a number in the range 0 to 100 and is obtained by calculating the weighted average of the student's performance in the assessment components. The criteria for calculating the weighted average is as defined below: The proposal is worth 40% of the final grade, and the final dissertation is worth 60% of the final grade. A grade is to be awarded for the students as follows: An overall mark of 80 or higher is an HD, an overall mark of 70 or higher (but less than 80) is a D, an overall mark of 60 or higher (but less than 70) is a C, an overall mark of 50 or higher (but less than 60) is a P, and an overall mark below 50 is an N. Client class: The client program will allow entry of these data for several different student into anArrayListand then perform some analysis and queries. Your client class (program) will provide the user with a menu to perform the following operations. You will also need to load the information of the students froma CSV file (student.csv)before displaying the menu. You only need one ArrayList and one menu for this. For the csv file, your first item can be C or R to differentiate whether the entry is creating a Student_Course object, or a Student_Research object. You can then decide how you want other data to be listed in the csv file. Make sure you provide documentation to explain how your data is listed in the csv file. You should specify clearly in your documentation the data format of the CSV files used in this assignment. 1. Quit (exit the program) 2. Add (to the ArrayList) all the marks information about a course work student or a research student by reading it fromanother CSV file. Your program will ask for the file name. 3. Given student number (ID), remove the specified student and relevant information from the ArrayList. It is always good to ask the user to confirm again before removing the record. For confirmation, output the student number (ID) and the name to the user. 4. Output all details currently held in the ArrayList. 5. Determine and display how many course work students obtained an overall mark equal to or above the average overall mark and how many obtained an overall mark below the average overall mark. Note: You only need to perform this task on course work students only. 6. Given a student number (ID), report the grade information (using reportGrade) of the student with that number. If the student is not found in the ArrayList, an appropriate error message is to be displayed 7. Sort the ArrayList of the student objects into ascending order of the students' numbers (IDs), and output the sorted array - implement bubble sort algorithm for this, and explain how this sorting algorithm is different to the insertion sort algorithm (in external documentation). 8. Output the sorted ArrayList from (7) toa CSV file. If the ArrayList is not sorted, this option cannot be selected. Remember to include the identification of whether the student is course work student (C) or research student (R).

Note that the program will loop around until the user selects the first option (Quit). Set up a student ArrayList of N student objects, and test it with N = 10 (at least). You have to store your test data in a file so that your program can read them. You should use 5 course work students and 5 research students in your test. Consider all possible enrolment types in your test. The client class should be well-structured and should have the essential methods in addition to the main method. The interaction with the user can be via the command line (i.e., no graphical user interface is expected). Devise suitable test data to test all sections of program code. You will need to provide all the test data used. Your client program should also include a method (e.g., StudentInfo( )) to output your student details (name, student number, mode of enrolment, tutor name, tutorial attendance day and time) at the start of program results. Note: The question requires you to use an ArrayList. Also, the sorting algorithm used must be coded within your program and not called from any Java libraries. You should not use any Java libraries for sorting algorithm and output to CSV file (e.g. FileWriter). You are required to use only materials covered in the lecture notes and the textbook to complete this assignment.
