+# 数学题目生成系统
+
+## 项目简介
+
+这是一个基于 Java 的命令行应用程序，用于为小学、初中和高中教师生成数学题目试卷。系统支持用户登录、题目查重、按难度生成题目，并保存为文本文件。
+
+## 功能特点
+
+- **多角色登录**：支持小学、初中、高中教师登录
+- **题目生成**：根据学段生成不同难度的数学题目
+- **题目查重**：自动检查题目是否重复，确保唯一性
+- **试卷保存**：将生成的题目保存为带时间戳的文本文件
+- **模式切换**：教师可在登录后切换出题学段
+- **多次生成**：教师登录后能生成无限次试卷

+## 类说明
+
+- **paper**: 存储教师生成的试卷文件和账号密码本
+- **src/paper/**: 试卷生成相关类，负责创建和保存试卷
+- **src/problem/**: 题目生成相关类，负责生成各类数学题目
+- **src/teacher/**: 教师管理相关类，处理教师登录和权限
+- **out/**: Java编译后的class文件输出目录
+
+## 使用说明
+
+### 登录系统
+
+运行程序后，输入用户名和密码（格式：`用户名 密码`），系统会根据密码本验证身份并进入对应学段的出题模式。
+
+### 生成题目
+
+登录成功后，系统会提示输入题目数量（10-30之间，包括10和30），输入后即可生成试卷并保存至 `./doc/教师姓名/` 目录下。
+
+### 切换学段
+
+在出题模式下，可输入以下指令切换学段：
+- `切换为小学出题`
+- `切换为初中出题`
+- `切换为高中出题`
+
+
+### 退出登录
+
+输入 `-1` 可退出当前用户，返回登录界面。
+
+## 题目类型示例
+
+- **小学**：四则运算，如 `12+（34-56）÷7=`
+- **初中**：含平方和开方，如 `√25+3²=`
+- **高中**：含三角函数，如 `sin30+cos60=`
+
+## 文件存储
+
+- 生成的试卷以当前时间命名，格式为：`yyyy-MM-dd-HH-mm-ss.txt`
+
+- 保存在对应用户的文件夹下，例如：`./doc/张老师/2025-09-26-14-30-15.txt`
+
+- 若不存在该路径，程序将自动在运行目录中创建该路径的相关文件夹
+
+## 运行环境
+
+1. Java 8 或更高版本的IDE
+2. PowerShell控制台环境（支持标准输入输出）：
+- 方式1（不使用JAR包）：在GenerateMath文件夹下进入终端，使用命令
`[Console]::InputEncoding = [System.Text.Encoding]::UTF8 `
+ `[Console]::OutputEncoding = [System.Text.Encoding]::UTF8`
`java -cp "out\production\GenerateMath" Main -Dfile.encoding=UTF-8`
+- 方式2（使用JAR包）：在存放JAR包的文件目录下打开终端，使用命令
`[Console]::InputEncoding = [System.Text.Encoding]::UTF8 `
+ `[Console]::OutputEncoding = [System.Text.Encoding]::UTF8`
`java -jar GenerateMath.jar`
+3. cmd模式下：将PowerShell环境下的前两条命令修改为`chcp 65001`
+
+## 注意
+1. 登陆时账号和密码之间只能间隔一个空格，且密码后不能携带任何空白字符
+2. 任何命令语句都要严格按照所给字符串输入，其前后不能携带任何空白字符
+3. 填写出题数量时数字前后不能携带任何空白字符
+
+
+## 未来展望
+
+未来可考虑添加以下功能：
+- 图形用户界面
+- 自定义题目模板
+- 试卷导出为多种格式
