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。文字步骤详细。

设计一个简单的学校人事管理系统，管理教师和学生信息，需要以下步骤：

1. 定义教师和学生的类，包括编号、姓名、性别、出生日期等基本信息，并分别添加部门、职称、工资、高考分数、专业field、班级等属性。

2. 实现教师和学生信息的添加，可以通过创建教师和学生对象，并将其添加到相应的列表中。

3. 实现教师和学生信息的删除，可以通过指定教师或学生的编号或姓名，从相应的列表中删除教师或学生对象。

4. 实现教师和学生信息的修改，可以通过指定教师或学生的编号或姓名，从相应的列表中找到教师或学生对象，并修改相应的属性。

5. 实现教师和学生信息的查询，可以通过指定教师或学生的编号或姓名，从相应的列表中找到教师或学生对象，并输出其所有属性。
