With the below being the base code, 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$)$

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.

Student Class Code:

$//$ Base class Student

public class Student $\{$

$//$ Private attributes

$$ private String firstName;

$$ private String lastName;

$$ private long studentID;

$//$ Constructor to initialize all fields

$$ public Student$($String firstName, String lastName, long studentID$)\{$

$$ this.firstName $=$ firstName;

$$ this.lastName $=$ lastName;

$$ this.studentID $=$ studentID;

$\}$

$//$ Getter for first name

$$ public String getFirstName$()\{$

$$ return firstName;

$\}$

$//$ Setter for first name

$$ public void setFirstName$($String firstName$)\{$

$$ this.firstName $=$ firstName;

$\}$

$//$ Getter for last name

$$ public String getLastName$()\{$

$$ return lastName;

$\}$

$//$ Setter for last name

$$ public void setLastName$($String lastName$)\{$

$$ this.lastName $=$ lastName;

$\}$

$//$ Getter for student ID

$$ public long getStudentID$()\{$

$$ return studentID;

$\}$

$//$ Setter for student ID

$$ public void setStudentID$($long studentID$)\{$

$$ this.studentID $=$ studentID;

$\}$

$//$ Method to compare two students based on student ID

$$ public boolean equals$($Student otherStudent$)\{$

$$ return this.studentID $==$ otherStudent.studentID;

$\}$

$//$ Method to report grade $($prints a message, meant to be overridden in child classes$)$

$$ public void reportGrade$()\{$

$$ System.out.println$("$There is no grade here."$)$;

$\}$

$//$ Method to display student information

$$ public void displayStudentInfo$()\{$

$$ System.out.println$("$Student Name: $"+$ firstName $+""+$ lastName$)$;

$$ System.out.println$("$Student ID: $"+$ studentID$)$;

$\}$
