Student类表示学生,包含名字和年龄等属性。 要获取School对象中的学生属性值,可以通过以下代码实现: Schoolschool=newSchool();// 添加学生school.getStudents().add(newStudent("Alice",18));school.getStudents().add(newStudent("Bob",19));// 获取学生信息List<Student>students=school.getStudents();for(Stu...

首先可以在 School 类中添加私有属性 students,代表学生集合。然后在该类中添加一些公共的方法,例如 addStudent 和 removeStudent,用于向集合中添加或删除学生,并添加一个公共的方法 getStudents,用于获取学校的所有学生。由于该集合已经被封装起来,因此只有通过相应的方法才能访问该集合,从而实现更好的封装性和安全性。
