## 1、下载JDK安装包，下载地址： ##

> 安装过程按照提示一步一步执行，注意jre安装路径要和jdk保持在一个路径下。

## 2. 配置java环境变量： ##

右击【我的电脑】->【属性】->【高级系统设置】->【环境变量】  
(1)、新建系统变量JAVA\_HOME，值为jdk安装路径

> 变量名：JAVA\_HOME  
> 变量值：jdk安装路径![65b7b49c9271dade42f49e350fdb54e0.png][]

(2)、新建系统变量CLASSPATH，值为： %JAVA\_HOME%\\lib\\dt.jar;%JAVA\_HOME%\\lib\\tools.jar;

> 变量名：CLASSPATH  
> 变量值：%JAVA\_HOME%\\lib\\dt.jar;%JAVA\_HOME%\\lib\\tools.jar;![5df3a528c15d92c865ae267847523ba4.png][]

(3)、增加用户变量Path的值：%JAVA\_HOME%\\bin;%JAVA\_HOME%\\jre\\bin;并换到第一个位置

> 变量名：Path  
> 变量值：  
> %JAVA\_HOME%\\bin  
> %JAVA\_HOME%\\jre\\bin![27a77f3942234719331343d34dc9653d.png][]

验证java环境是否配置成功：cmd窗口输入命令java -version，若配置成功则会输出安装java的相应版本![47e2a98e62bfa1802afc76294d597a42.png][]
