进入Java学习第一步即是安装配置各种环境，下面将重点介绍JDK安装详细图文版。

1.  进入Oracle官网下载对应的JDK（根据自己的电脑(32位还是64位)选择对应的版本下载）

3.  选择安装路径：路径最好不要有中文名，默认安装路径为:"C:\\Program Files\\Java\\jdk版本"。可以默认安装，也可以自定义安装(建议)。选好之后点击下一步，记住安装路径，后续配置环境变量会使用到。

在变量值一行的末尾输入:";%JAVA\_HOME%\\bin" 必须是英文。之后确定即可。到此环境变量已经配置好了。

7.配置好环境变量之后，查看是否配置成功。

打开dos cmd命令窗口，输入"java -version"。出现如下界面，jdk安装成功。
