set集合如何遍历

Session session = HibernateSessionFactory.getSession();
Teacher t = (Teacher) session.load(Teacher.class, 101);
System.out.println(t.getTname());


Set<Student> students = t.getStudents();
Iterator<Student> iterator = students.iterator();
while (iterator.hasNext()) {
Student student = iterator.next();
System.out.println(student.getSname());

}
