public class AddStudent {

        void AddStu() {
        System.out.println("输入学生编号:");
        int id=scan.nextInt();

        System.out.println("输入生日:");
        int birthday=scan.nextInt();
       save(id,name,sex,enter,birthday);
       scan.close();
     
       }
        private void save(int id, String name, String sex, String enter,
