教师类，636f707962616964757a686964616f31333335333761课程类类似。
以下是实现：public static void main(String [] args){
Student s1 = new Student(1);
Teacher t1 = new Teacher(1);
Teacher t2 = new Teacher(2);
Course c1 = new Course(1);
Course c2 = new Course(2);
Set studentSet = new HashSet();
studentSet.add(s1);
Set teacherSet = new HashSet();
teacherSet.add(t1);
teacherSet.add(t2);
Set courseSet = new HashSet();
courseSet.add(c1);
courseSet.add(c2);
s1.setTeachers(teacherSet );
t1.setStudents(studentSet);
t2.setStudents(studentSet);
s1.setCourses(courseSet);
c1.setStudent(studentSet);
c2.setStudent(studentSet);
//老师课程同理
}
