Model of ExecutionLive Examples Lecture QuestionQuestion: in a package named “execution”, implement the following classes: Class Battery with: A constructor that takes a variable named “charge” of type Int Class Flashlight with: A constructor that takes no parameters When a new Flashlight is created, declare a state variable named “battery” of type Battery and set it to a new Battery with 5 charge (ie. Batteries included) A method named “use” that takes no ...

原因以我用GitHub.io搭我的博客为例，GitHub会生成一个CNAME文件来进行域名重定向。但是当你使用 hexo d指令是会导致建好的CNAME文件被覆盖 / 删除。这时你又要重新去生成CNAME文件，十分的繁琐。 解决方案问题也很好解决，既然hexo默认没有 CNAME 文件，那我们在本地生成一个 local CNAME 即可解决问题，步骤也非常的简单。 首先在终端cd到你的博客根目录，接着cd到 source 文件夹， 1cd source 输入以下指令生成CNAME文件： 1touch CNAME 创建完成后使用 vim 指令打开 CNAME文件，并输入你的自定义域名： 1vim CNAME 修改完 CNAME 文件保存退出即可，后续再使用 hexo d 时就不会出现这种情况。

绝对路径在你的博客的根目录中，进入 source 文件夹，新建一个 image 文件夹。你可以将需要加载的图片统统放在这里，但是并不建议这么做，因为当文章多起来的时候就显得很乱，很难去整理。 1 我一般是将主页的图片素材放入此文件夹，文章图片我更推荐下方操作。 相对路径这种方法是对每一个文章新建一个同名的文件夹，用于放入对该文章的素材，比较推荐。首先你需要修改你的 _config.yml,将 post_asset_folder 改为 true： 1post_asset_folder: true 后续创建新文章的时候就会生成同名文件夹，图片丢进去即可。需要注意的是，在使用此方法之前的文章需要你自己创建同名文件夹，系统并不会补上。
