基于swing的背单词系统

该小应用是本人学习Java前期制作的程序，可能还有着一些Bug没有修复，敬请谅解！该应用用到了图形化界面、I/O流本地磁盘读取/写入数据、键盘事件、焦点事件、监听事件等知识。该应用拥有功能：
file菜单项：打开文件、保存文件、另存为文件、写入反馈文件。
edit菜单项：修改数据、检查中文拼写、检查英文拼写、查找单词。
源代码：

程序界面：
在这里插入图片描述
除了源代码，还需要在本地D：//Program文件夹中插入如下四张图片或者文件名相同，大小接近的任意六张图片作为按钮

第一列文本框是中文，是第二列文本框中的英文的中文翻译，可自定义中文意思（按下前两个按钮后再按第三个按钮，全部文本框为可编辑状态）
第二列文本框是英文，是第一列文本框中的中文的英文翻译，可自定义中文意思（按下前两个按钮后再按第三个按钮，全部文本框为可编辑状态）
第三列文本框是检查文本框，当用户隐藏了中文一列，或者英文一列，在第三列输入对应的翻译，会显示拼写正确与否
