$1.$ Class Design

Create the following classes, one for each CSV file:

Student, Teacher, Course, Department

Define shared properties $($e$.$g$.,$ id$,$ name$)$ in an abstract class and include common methods for all entities.

Use an interface to define shared behaviors $($e$.$g$.,$ displayInfo$()$ method to print details for any entity$).$

$2.$ FileReader Class

Implement a FileReader class with methods to read CSV files and return ArrayList objects:

loadStudents$($String fileName$)$: Reads students.csv and returns ArrayList.loadTeachers$($String fileName$)$: Reads teachers.csv and returns ArrayList.loadCourses$($String fileName$)$: Reads courses.csv and returns ArrayList.loadDepartments$($String fileName$)$: Reads departments.csv and returns ArrayList.

Error Handling:

Handle file I$/$O errors and invalid data formats using exception handling.

$3.$ SchoolManagementSystem Class

Create a SchoolManagementSystem class with methods to answer the following questions:

Department with Maximum Students: Print the department name with the most students.Teacher Advising Minimum Students: Print the name of the teacher advising the fewest students.Department Chairs: Print the names of department chairs.Students Missing Nationality: Count and print the number of students with missing nationality.Course Instructors: Print the name of the instructor for each course.

Error Handling:

Implement custom exceptions for scenarios such as missing instructor IDs, missing department IDs, or incomplete data.Handle exceptions gracefully within the SchoolManagementSystem class.

$4.$ Testing

Create a TestSchoolManagementSystem class with a main method to:

Test all functionalities of the SchoolManagementSystem class.Display answers to the questions from the previous section $($e$.$g$.,$ "Department with Maximum Students", "Teacher Advising Minimum Students", etc.$).$

Deliverables:

Use proper Object$-$Oriented Programming $($OOP$)$ principles:

Abstract classesInterfacesEncapsulation and inheritance

Demonstrate file reading and parsing to populate ArrayList objects for each class.

Implement robust error management with exception handling.

Develop a main class to test and display results for all questions.
