### 一、jdk的下载 ###

[jdk下载路径![icon-default.png?t=N176][icon-default.png_t_N176]https://www.oracle.com/cn/java/technologies/downloads/\#jdk19-windows][jdk_icon-default.png_t_N176_icon-default.png_t_N176_https_www.oracle.com_cn_java_technologies_downloads_jdk19-windows]![cb01865659244769b31bd871487dcb1c.png][]

如果想下载以往的历史版本可点击 Java archive 进行选择

这里我演示的是Java17版本的

点击所下载的exe安装包进行安装

如果不想安装默认C盘地址可以自行选择更改修改安装地址。

注：安装目录不要包含中文

从命令行进入所安装的Java17目录下的bin 输入 java -version，如果显示java版本即安装成功
