1. 假设现在有本科生打算在毕业之后考研,考研的录取分数线为320,包含四门课程,政治、英语、数学、专业课程,学生的字段属性包含姓名、性别、专业、毕业院校等字段。
2. 首先利用集合类ArrayList生成一个具有N(由你自己通过键盘输入个数)个学生的集合,对学生按照要求的字段进行初始化。
3. 定义考研“录取”接口,该接口的主要功能是根据考试分数确定是否考生上线(总分达到要求,单科成绩不低于60分),最后根据录取情况输出参加考试的学生名单、考研上线的学生名单并输出各科考试成绩

就是往list里面添加sutdent对象而已
要自己输入N阿?
Scanner scan=new Scanner(System.in);
String input = scan.toString();
List<Student> stuList = new ArrayList<Student>(int i = Integer.parseInt(input););
addStudentsInfo(stuList);
加到里面你试试 我是新手
