这两年 AI 发展迅猛，作为开发人员，我们总是追求更快、更高效的工作方式，AI 的出现可以说改变了很多人的编程方式。

AI 对我们来说就是一个可靠的编程助手，给我们提供了实时的建议和解决方案，无论是快速修复错误、提升代码质量，或者查找关键文档和资源，AI 作为编程助手都能让你事半功倍。

今天为大家推荐一款适配了 Visual Studio，VS Code，JetBrains 系列(本文使用)以及 Vim 等多种编译器环境的插件 Fitten Code，Fitten Code 是由非十大模型驱动的 AI 编程助手，它可以自动生成代码，提升开发效率，帮您调试 Bug，节省您的时间，另外还可以对话聊天，解决您编程碰到的问题。

Fitten Code 免费且支持 80 多种语言：Python、C++、Javascript、Typescript、Java等。

目前对于 Java，Fitten Code 支持在多种文本编辑器或 IDE 上使用，接下来我们来详细看看在 IntelliJ IDEA 上的安装与使用：

• 1. 安装
• 2. 智能补全
• 3. AI问答
• 4. 生成代码
• 5. 代码翻译
• 6. 生成注释
• 7. 解释代码
• 8. 生成测试
• 9. 检查 BUG
• 10. 编辑代码

1、安装

点击左上方"文件"再点击"设置"，如下图所示

接着点击左侧"插件"选择"Marketplace"，并搜索"Fitten Code"，然后点击"Install"进行安装

安装完成后左侧会出现 Fitten Code 插件图标,注册登录后即可开始使用

2、智能补全

打开代码文件，输入一段代码，Fitten Code 就会为您自动补全代码：

按下 Tab 键接受所有补全建议：

按下 Ctrl+→ 键接收单个词补全建议：

3、AI 问答

用户可通过点击左上角工具栏中的Fitten Code – 开始新对话打开对话窗口进行对话：

可以选中代码段再右键选择"Fitten Code - 开始对话"进行对话，Fitten Code 会自动引用用户所选中的代码段，此时可直接针对该代码段进行问询等操作：

4、生成代码

可在左侧 Fitten Code 工具栏中选择 "Fitten Code - 生成代码"  ，如下图所示：

然后在输入框中输入指令即可生成代码：

利用注释后的自动补全功能生成代码

也可以利用对话功能生成代码

5、代码翻译

Fitten Code可以实现代码的语义级翻译，并支持多种编程语言之间的互译。有以下两种方法可以实现。

（1）选中需要进行翻译的代码段，右键选择"Fitten Code – 编辑代码"，然后在输入框中输入需求即可完成转换

（2）选中需要进行翻译的代码段，点击左侧工具栏中的"Fitten Code – 开始对话"。然后在输入框中输入需求即可完成转换

6、生成注释

Fitten Code 能够根据您的代码自动生成相关注释，通过分析您的代码逻辑和结构，为您的代码提供清晰易懂的解释和文档，不仅提高代码的可读性，还方便其他开发人员理解和使用您的代码。先选中需要生成注释的代码段，然后右键选择 "Fitten Code – 生成注释"：
