## 三、配置环境变量： ##

1. 打开环境变量配置。计算机→属性→高级系统设置→高级→环境变量，在系统变量中配置。

2. 配置JAVA\_HOME。新建，变量名JAVA\_HOME，变量值，jdk路径，我的路径是C:\\Program Files\\Java\\jdk1.8.0\_121，保存。

3. 配置CLASSPATH。新建，变量名CLASSPATH，变量值，.;%JAVA\_HOME%\\lib;%JAVA\_HOME%\\lib\\tools.jar（第一个分号前前面有一个点）。

4. 配置Path。打开Path变量，在变量值最前加入%JAVA\_HOME%\\bin;%JAVA\_HOME%\\jre\\bin;

## 四、验证： ##

运行cmd，输入java -version，显示java版本则成功。
