练习4
用python代码实现
- name: string
- email: string
+ get_info(): string
}
class Student {
- courses: List<Course>
+ add_course(course: Course)
+ remove_course(course: Course)
+ get_courses(): List<Course>
+ get_info(): string
}
class Teacher {
- courses: List<Course>
+ add_course(course: Course)
+ remove_course(course: Course)
+ get_courses(): List<Course>
+ get_info(): string
}
class Admin {
+ add_student(student: Student)
+ remove_student(student: Student)
+ add_teacher(teacher: Teacher)
+ remove_teacher(teacher: Teacher)
+ add_course(course: Course)
+ remove_course(course: Course)
}
class Course {
- name: string
- teacher: Teacher
- students: List<Student>
+ get_info(): string
}
Student *-- Course
Teacher *-- Course
Course "1"--o "1" Teacher
Course "1"--o "1..*" Student
Admin ..> Person
Person <|-- Student
Person <|-- Teacher
