一、JDK下载

首先要下载java开发工具包JDK，下载地址：http://www.oracle.com/technetwork/java/javase/downloads/index.html

点击如下下载按钮：

然后就会出现如下图所示的画面：

在"系统变量"中设置3项属性，JAVA\_HOME，PATH，CLASSPATH(大小写无所谓),若已存在则点击"编辑"，不存在则点击"新建"。

变量设置参数如下：

变量名：**JAVA\_HOME**

变量值：**D:\\tools\\jdk1.8.0\_77   **     // 要根据自己的实际路径配置

![format_png 5][]

变量名：**CLASSPATH**

变量值：**.;%JAVA\_HOME%\\lib\\dt.jar;%JAVA\_HOME%\\lib\\tools.jar;**         //记得前面有个"."

![format_png 6][]

变量名：**Path**

变量值：**%JAVA\_HOME%\\bin;%JAVA\_HOME%\\jre\\bin;**

![format_png 7][]

至此，系统环境变量配置成功。

三、测试JDK是否安装成功

1、"开始"->"运行"，键入"cmd"（或快捷键win+R）；

2、键入命令: **java -version**、**java**、**javac** 几个命令，出现以下信息，说明环境变量配置成功；
