# 1、jdk 的 下载 #

## 1.1 官网下载地址 ##

这里我选择的是 `jdk8`

https://www.oracle.com/java/technologies/javase-downloads.html

**这里以为下载需要登录所以我准备了百度网盘**

## 1.2 百度网盘下载 ##

链接：https://pan.baidu.com/s/1uBm0XqBtbdafWgn_YUSWLA 
    提取码：2mqh

# 2、新建文件夹 #

## 2.1、新建Java文件夹 ##

**我这里选择的是安装的文件夹 我在H盘里面新建了个java文件夹，这里盘符可以改的C D E啥都无所谓**

## 2.1、新建JDK JRE 文件夹 ##

**进去java文件里新建两个文件 JDK JRE**

# 3、安装 #

**首先双击程序管理员打开**

**选择我们刚刚创建的JDK文件的目录**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzczMTUzMg_size_16_color_FFFFFF_t_70 4]

**下一步我等了半天，原来是window窗口缩小化了=、=**

点击这个就是显示出来jre安装框框

**选择我们的刚刚创建JRE安装的路径**

**好了java到这里就是安装成功了  
结束了？  
不可能，我们还要配置环境变量**

# 4、环境变量配置 #

**找到我的电脑（也就是计算机，此电脑 等等)我这里就是此电脑**

**变量名 不用改，变量值改为刚刚你配置的JRE路径**  
![在这里插入图片描述][20210111093521911.png]  
**弄完后点击确定**
