OOP Concepts
Introduction
It is required to implement a software for a college.
The college has departments for example (Computer, Electricity, Mechanical,..etc).
Each department has some courses for example (Math, OOP, Law,..etc) Also, there are many professors and students in the college.
Requirements
It is required from you to implement a simple system for the college. We will extend this assignment features/requirements in the next assignments in this course.
Implement each entity (College, Department, Course, Professor, Student) as a class with the following attributes/methods…
College
Attributes: departments, students, professors, courses
Methods:
int numberOfDepartments() int numberOfCourses() int numberOfProfessors() int numberOfStudents()
Department findDepartment(String name) // find department with name
Student findStudent(String name) // find student by full name
Professor findProfessor(String name) // find professor by full name
Course findCourse (String name) // find course by its name
Department
Attributes: name, description, max_number_of_students, courses, students
Methods:
int numberOfCourses() int numberOfStudents()
Course findCourse(String name) // find course by name boolean isFull() // return true if number of students equals max number of students
boolean enroll(Student s) // assign student to this department. Student can’t be enrolled to department if the department is full
Course
Attributes: name, description, max_number_of_students, number_of_lectures, students, professor, department.
Methods:
int numberOfStudents()
boolean assignProfessor(Professor p) // assign professor to course. Course can have only one professor. void unassignProfessor(Professor p) // dessign professor from course. boolean isAssigned() // return true if course is assigned to a professor. String professorName() // return professor full name boolean isFull() // return true if number of students equals max number of students
boolean enroll(Student s) // assign student to this course. Student can’t be enrolled to a course if the course is full. Student can’t be enrolled to a course if he isn’t enrolled in its department.
Professor
Attributes: firstName, lastName, telephone, address, salary, courses.
Methods:
String fullName() // return “firstName lastName” double getRaise(double ratio) // recalculate professor salary
Student
Attributes: firstName, lastName, telephone, address, age, department, courses
Methods:
String fullName() // return “firstName lastName”
Notes:
You should implement constructors for each class.
You should implement getters and setters when needed.
User can’t create new colleges. You will have only one college object in your main test class.
You can add more attributes/methods to any class if you need.
The fixed size for any array is 50 All objects names will be unique.
