用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。

好的，以下是一个简单的学校人事管理系统的Java代码实现：

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

public class SchoolManagementSystem {
    private ArrayList<Student> students;
    private ArrayList<Teacher> teachers;

    public SchoolManagementSystem() {
        students = new ArrayList<>();
        teachers = new ArrayList<>();
    }

    public void addStudent(Student student) {
        students.add(student);
    }

    public void addTeacher(Teacher teacher) {
        teachers.add(teacher);
    }

    public void removeStudent(int id) {
        for (int i = 0; i < students.size(); i++) {
            if (students.get(i).getId() == id) {
                students.remove(i);
                return;
            }
        }
        System.out.println("学生不存在！");
    }

    public void removeTeacher(int id) {
        for (int i = 0; i < teachers.size(); i++) {
            if (teachers.get(i).getId() == id) {
                teachers.remove(i);
                return;
            }
        }
        System.out.println("教师不存在！");
    }

    public void updateStudent(int id, Student newStudent) {
        for (int i = 0; i < students.size(); i++) {
            if (students.get(i).getId() == id) {
                students.set(i, newStudent);
                return;
            }
        }
        System.out.println("学生不存在！");
    }

    public void updateTeacher(int id, Teacher newTeacher) {
        for (int i = 0; i < teachers.size(); i++) {
            if (teachers.get(i).getId() == id) {
                teachers.set(i, newTeacher);
                return;
            }
        }
        System.out.println("教师不存在！");
    }

    public void queryStudent(int id) {
        for (int i = 0; i < students.size(); i++) {
            if (students.get(i).getId() == id) {
                System.out.println(students.get(i));
                return;
            }
        }
        System.out.println("学生不存在！");
    }

    public void queryTeacher(int id) {
