jdk9.0.1如何在win10中配置环境变量

本文详细介绍了如何从Oracle官网下载JDK9,并完成安装过程。针对安装完成后可能出现的‘javac不是内部或外部命令’的问题,给出了具体的解决办法,包括如何设置JAVA_HOME、JRE_HOME、path和classpath等环境变量。

  首先我们登陆oracle官网下载JDK9:

  接着照着提示安装就行,安装完后你在控制台输入javac会发现“javac不是内部或外部命令”等字样。

说明我们安装完后并没有配置环境变量。

  需要我们到高级系统设置中的环境变量进行设置:

  其中有4个选项是需要我们编辑的,两个来自创建:

JAVA_HOME和JRE_HOME是需要我们创建的,路径来自与你安装jdk时的路径,找到并复制粘贴即可

接下来是path和classpath的设置:

  全部设置完后我们保存设置并到控制台输入javac或java -version,你就能看到当前的java的版本等内容,表示已配置成功
