java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。

以下是一个简单的学校人事管理系统的Java代码示例：

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

public class SchoolManagementSystem {
    ArrayList<Teacher> teachers = new ArrayList<Teacher>();
    ArrayList<Student> students = new ArrayList<Student>();
    Scanner scanner = new Scanner(System.in);

    // 添加教师
    public void addTeacher() {
        System.out.println("请输入教师编号：");
        int id = scanner.nextInt();
        scanner.nextLine();
        System.out.println("请输入教师姓名：");
        String name = scanner.nextLine();
        System.out.println("请输入教师性别：");
        String gender = scanner.nextLine();
        System.out.println("请输入教师出生日期：");
        String birthDate = scanner.nextLine();
        System.out.println("请输入教师部门：");
        String department = scanner.nextLine();
        System.out.println("请输入教师职称：");
        String title = scanner.nextLine();
        System.out.println("请输入教师工资：");
        double salary = scanner.nextDouble();
        Teacher teacher = new Teacher(id, name, gender, birthDate, department, title, salary);
        teachers.add(teacher);
        System.out.println("教师添加成功！");
    }

    // 添加学生
    public void addStudent() {
        System.out.println("请输入学生编号：");
        int id = scanner.nextInt();
        scanner.nextLine();
        System.out.println("请输入学生姓名：");
        String name = scanner.nextLine();
        System.out.println("请输入学生性别：");
        String gender = scanner.nextLine();
        System.out.println("请输入学生出生日期：");
        String birthDate = scanner.nextLine();
        System.out.println("请输入学生高考分数：");
        double score = scanner.nextDouble();
        scanner.nextLine();
        System.out.println("请输入学生专业：");
        String field = scanner.nextLine();
        System.out.println("请输入学生班级：");
        String className = scanner.nextLine();

        System.out.println("学生添加成功！");
    }

    // 删除教师
    public void deleteTeacher() {
        System.out.println("请输入要删除的教师编号：");
        int id = scanner.nextInt();
        for (int i = 0; i < teachers.size(); i++) {
