Question First, you need to design, code in Java, test and document a base class, Student. The Student class will have the following information, and all of these should be defined as Private: ICT167 Assignment 2 2 September Trimester 2021 A. A first name (given name) B. A last name (family name/surname) C. Student number (ID) - an integer number (of type long) D. A date of birth (in day/month/year format – three integers) - (Create your own Date class, the Date class should be a separate class from this. Do NOT use the Date class from JAVA.) The Student class will have at least the following constructors and methods: (1) 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 reportGrade method, 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 equals method which 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 Undergraduate Student class, a Graduate Student class (both derived from the Student class) a UndergraduateUnit class, GraduateUnit 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 undergraduate students (Undergraduate Student class): (a) Contain information of the UndergraduateUnit object (assuming that there is only one unit) (b) Provide a reportGrade method such that it will output “U” (to identify as undergraduate student), the Name (first name and last name), Student number, the unit ID, the overall mark, and the final grade of the student.
For undergraduate students (Undergraduate Student class): (a) Contain information of the UndergraduateUnit object (assuming that there is only one unit) (b) Provide a reportGrade method such that it will output “U” (to identify as undergraduate student), the Name (first name and last name), Student number, the unit ID, the overall mark, and the final grade of the student. For graduate students (Graduate Student class): (a) Contain information of the GraduateUnit object (assuming that there is only one unit) (b) Provide a reportGrade method such that it will output “G” (to identify as graduate student), the Name (first name and last name), Student number, enrolment type and the final grade of the student. Unit class: (a) Enrolment type: "U" for undergraduate and "G" for graduate (b) A final grade reporting method for reporting the “NA” for not available. Undergraduate unit (UndergraduateUnit class): (a) Will have the information of the unit ID (of type string; e.g. ICT167), and the level of the unit (of type integer; e.g. 1 for first 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. ICT167 Assignment 2 September Trimester 2021 (c) There is weekly practical work. The marks for this component are recorded as a total mark obtained (marked out of a maximum of 20 marks) for all practical work demonstrated during the semester. (d) There is one final examination that is marked out of a maximum of 100 marks and recorded separately. (e) An overall mark (to be calculated within the class) (f) A final grade, which is a string (avoid code duplication for calculating this) The final grade, for undergraduate students, 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 final grade, for undergraduate students, 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 50% (25% each) of the final grade, the practical work is worth 20%, and the final exam is worth 30% of the final grade. A grade is to be awarded for undergraduate 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. Graduate unit (GraduateUnit class): (a) Enrolment type of the graduate student; whether the student is a Master or PhD student (of type string; e.g. Master or PhD) (b) The number of years used to complete the thesis of type integer, e.g. 3 for taking three years to complete). (c) A final grade, which is a character (C for completed; N for not completed; S for suspended) Client class: The client program will allow entry of these data for several different student into an ArrayList and 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 from a 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 U or G to differentiate whether the entry is creating a Undergraduate Student object, or a Graduate Student object. You can then decide how you want other data to be 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 an undergraduate or graduate student by reading it from another 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 undergraduate 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 can only perform this task on undergraduate 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 an appropriate sorting algorithm for this, and explain why such algorithm is selected (in internal and external documentation). 8. Output the sorted ArrayList from (7) to a CSV file. If the ArrayList is not sorted, this option cannot be selected. Remember to include the identification of whether the student is undergraduate (U) or graduate (G) student. 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 undergraduate and 5 graduate 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 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, date 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.
