Windows操作系统下JDK的配置方法

本教程以JDK1.8为例。

1.先从官网下载下来jdk1.8，然后一步一步的安装就可以

配置JAVA_HOME变量，变量值是JDK的安装路径

图片81.png

配置CLASSPATH变量切记前面要带一个“.”，配置路径直接粘贴就可以：”.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar”

图片82.png

配置Path变量直接在path后面添加即可，前面带的分号，用于跟原来的参数进行分隔。“;%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin”

3.然后在命令行下测试 java命令
