 ## 使用说明
 
+### 编译JAR文件
+
+#### 方法1：使用javac和jar命令（推荐）
+
+**步骤1：编译Java源文件**
+```bash
+# 创建输出目录
+mkdir -p out/production/project
+
+# 编译所有Java文件
+javac -d out/production/project -encoding UTF-8 src/*.java
+```
+
+**步骤2：创建MANIFEST.MF文件**
+```bash
+# 创建MANIFEST.MF文件（Windows PowerShell）
+New-Item -ItemType File -Name "MANIFEST.MF" -Value "Manifest-Version: 1.0`nMain-Class: MathQuestionGenerator`n"
+
+# 或者使用文本编辑器手动创建MANIFEST.MF文件，内容如下：
+# Manifest-Version: 1.0
+# Main-Class: MathQuestionGenerator
+```
+
+**步骤3：打包为JAR文件**
+```bash
+# 创建JAR文件（只包含src文件夹的内容）
+jar cfm MathQuestionGenerator.jar MANIFEST.MF -C out/production/project .
+```
+
+**完整示例**：
+```bash
+# 在项目根目录下执行以下命令
+mkdir -p out/production/project
+javac -d out/production/project -encoding UTF-8 src/*.java
+New-Item -ItemType File -Name "MANIFEST.MF" -Value "Manifest-Version: 1.0`nMain-Class: MathQuestionGenerator`n"
+jar cfm MathQuestionGenerator.jar MANIFEST.MF -C out/production/project .
+java -jar MathQuestionGenerator.jar
+```
+
+#### 方法2：使用IDE（如IntelliJ IDEA）
+
+1. **打开项目**：在IDE中打开src文件夹
+2. **构建项目**：Build → Build Project
+3. **创建JAR**：File → Project Structure → Artifacts → JAR → From modules with dependencies
+4. **设置主类**：选择MathQuestionGenerator作为Main Class
+5. **构建JAR**：Build → Build Artifacts
+
