0.使用的系统
1.下载VS Code或VS Code Insiders
1.1 Windows下载方法
访问以下链接：Download Visual Studio Code - Mac, Linux, Windows
点击第一个链接 ，下载完毕后，按照步骤指引操作即可。
Insider Preview如何下载，访问这个：Download Visual Studio Code Insiders
点击下载链接，下载完毕后，按照步骤指引操作即可。
1.2 Ubuntu及Debian系下载方法
1.2.1 有Snap的
要运行的代码：
正常VS Code: sudo snap install code --classic
VS Code Insiders: sudo snap install code-insiders --classic1.3 其他下载方法
普通版本：Download Visual Studio Code - Mac, Linux, Windows
Insiders Preview: Download Visual Studio Code Insiders
下载好安装包后用自己系统解压安装包的指令解压即可。
2. 配置VS Code或Insiders
打开VS Code
选择与系统适配的主题
点击头像->Turn On Settings Sync
钩掉倒数第二个，并点击Sign in & Turn on
然后如果使用Github账号，两个选项都OK，如果用Microsoft Account，Insider选项请使用加入预览体验成员帐号登陆！
授权后即可同步。
3. 配置Java 运行环境
打开VS Code的extension界面
搜索Java，下载这个扩展：
下载后，点击Welcome -> Walkthroughs -> Get Started With Java Development
到这步，跟我走！！！
3.1 Java KDE配置
选择对应包并下载。（下面会以x64 Debian做示范，Windows用户们下载完毕后，打开安装包，跟着指引安装即可。
打开终端，输入
sudo apt install default-jdk输出结果应该是这样的：
