Question

Design, code in Java, test and document (at least) three classes – a CourseWorkStudent class, a
ResearchStudent class (which both derive from the Student class) and a Client program.
For coursework students:
(a) There are two assignments, each marked out of a maximum of 100 marks and equally weighted.
The marks for each assignment are recorded separately.
(b) 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.
(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 (think of a way to avoid code duplication for calculating this)
The final grade, for coursework 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.
For research students:
(a) There is a proposal component (marked out of a maximum of 100 marks).
(b) One final oral presentation (marked out of a maximum of 20 marks).
(c) One final thesis (marked out of a maximum of 100 marks).
(d) An overall mark (to be calculated within the class)
(f) A final grade, which is a string (think of a way to avoid code duplication for calculating this)
The final grade, for research 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 proposal component is worth 30% of the final grade, the final oral presentations are worth
a total of 10%, and the final thesis is worth 60% of the final grade
A grade is to be awarded for coursework and research 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.
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 need to think of a way to ask the user whether they are dealing with the coursework student
or research student. You will also need to load the information of the students from a text file
(student.txt) before displaying the menu. You only need one ArrayList and one menu for this.

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:
A. Title of the student (eg Mr, Miss, Ms, Mrs etc)
B.A first name (given name)
C. A last name (family name/surname)
D. Student number (ID) - an integer number (of type long)
E. A date of birth (in day/month/year format - three ints) - (Do NOT use the Date class from
JAVA)
The student class will have at least the following constructors and methods:
() two constructors - one without any parameters (the default constructor), and one with
parameters to give initial values to all the instance variables.
(ii) only necessary set and get methods for a valid class design.
(iii) method to write the output of all the instance variables in the class to the screen (which
will
be overridden in the respective child classes, as you have more instance variables that
required to be output).
(iv) an equals method which compares two student objects and returns true if they have the
same
student names, and the same date of birth, otherwise it returns false.
You may add other methods in the Student class as you see appropriate.
ICT167 Assignment 22 TJ, 2021
Design, code in.Java, test and document (at least) three classes - a CourseWorkStudent class, a
ResearchStudent class (which both derive from the Student class) and a Client program.
For coursework students:
(a) There are two assignments, each marked out of a maximum of 100 marks and equally
weighted.
The marks for each assignment are recorded separately.
(b) 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.
(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 (think of a way to avoid code duplication for calculating this)
The final grade, for coursework 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.
For research students:
(a) There is a proposal component (marked out of a maximum of 100 marks).
(b) One final oral presentation (marked out of a maximum of 20 marks).
