3、点击下一步

![JDK安装与环境变量配置(WIN7)\_JDK安装与环境变量配置(WIN7)\_02][JDK_WIN7_JDK_WIN7_02]

4、路径默认即可，无须改动点击下一步，安装jdk

8、安装完成后，配置环境变量 计算机→属性→高级系统设置→高级→环境变量

![JDK安装与环境变量配置(WIN7)\_JDK安装与环境变量配置(WIN7)\_08][JDK_WIN7_JDK_WIN7_08]

9、点击系统变量→新建

![JDK安装与环境变量配置(WIN7)\_JDK安装与环境变量配置(WIN7)\_09][JDK_WIN7_JDK_WIN7_09]

10、新建JAVA\_HOME变量，变量值为jdk的安装路径，后确定

11、系统变量→寻找Path变量→编辑

在变量值最后输入 %JAVA\_HOME%\\bin;%JAVA\_HOME%\\jre\\bin;

(注意原来Path的变量值末尾有没有；号，如果没有，先输入；号再输入上面代码)

![JDK安装与环境变量配置(WIN7)\_JDK安装与环境变量配置(WIN7)\_12][JDK_WIN7_JDK_WIN7_12]

12、系统变量→新建CLASSPATH变量

? 变量值填写 ?.;%JAVA\_HOME%\\lib;%JAVA\_HOME%\\lib ool.jar(注意最前面有一点)

![JDK安装与环境变量配置(WIN7)\_JDK安装与环境变量配置(WIN7)\_14][JDK_WIN7_JDK_WIN7_14]

13、系统变量配置完毕

14、检验是否配置成功，运行cmd输入java -version若如图所示，显示版本信息，则说明安装和配置成功。
