我需要java代码设计一个简单的学校人事管理系统,管理教师和学生信息。实现教师与学生基本信息的添加、删除、修改、查询。其中编号、姓名、性别、出生日期为共有的，教师包括部门、职称、工资；学生包括高考分数、专业field、班级等。

好的，以下是一个简单的学校人事管理系统的 Java 代码：

import java.util.ArrayList;
import java.util.Scanner;

public class SchoolManagementSystem {
    public static void main(String[] args) {
        ArrayList<Teacher> teachers = new ArrayList<>();
        ArrayList<Student> students = new ArrayList<>();
        Scanner scanner = new Scanner(System.in);

        while (true) {
            System.out.println("请选择操作：");
            System.out.println("1. 添加教师");
            System.out.println("2. 删除教师");
            System.out.println("3. 修改教师信息");
            System.out.println("4. 查询教师信息");
            System.out.println("5. 添加学生");
            System.out.println("6. 删除学生");
            System.out.println("7. 修改学生信息");
            System.out.println("8. 查询学生信息");
            System.out.println("0. 退出系统");

            int choice = scanner.nextInt();
            switch (choice) {
                case 1:
                    addTeacher(teachers, scanner);
                    break;
                case 2:
                    deleteTeacher(teachers, scanner);
                    break;
                case 3:
                    updateTeacher(teachers, scanner);
                    break;
                case 4:
                    queryTeacher(teachers, scanner);
                    break;
                case 5:
                    addStudent(students, scanner);
                    break;
                case 6:
                    deleteStudent(students, scanner);
                    break;

                    updateStudent(students, scanner);
                    break;

                    break;
                case 0:

在代码中，我们定义了两个类 `Teacher` 和 `Student` 来表示教师和学生。每个类都有一些属性（编号、姓名、性别、出生日期等）和对应的 getter 和 setter 方法。我们使用两个 `ArrayList` 对象来存储教师和学生信息，并在 `main` 方法中实现了添加、删除、修改和查询教师和学生信息的功能。
