## 第一步：下载 ##

#### \- 官网地址下载：[http://www.oracle.com/technetwork/java/javase/downloads/index-jsp-138363.html][http_www.oracle.com_technetwork_java_javase_downloads_index-jsp-138363.html] ####

#### \- 云盘下载1.8版本： 链接：https://pan.baidu.com/s/1vEzIk7tj4njdr6tFenlB4w ####

## 第二步：安装 ##

双击打开即可  
在这里可以设置安装路径，本人安装路径为**C:\\jinshu\\develop\\java\\jdk1.8.0\_181**，后面会用到。

后面一直下一步即可，直到安装完成。

## 第三步：配置JAVA\_HOME ##

##### 选择此电脑或者我的电脑右击 #####

##### 选择属性 #####

#### 选择高级系统设置 ####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NTE1MTk2MA_size_16_color_FFFFFF_t_70 3]

##### 选择环境变量 #####

##### 在系统变量中点击新建按钮，然后变量名填写为JAVA\_HOME, #####

##### 变量值就是刚才jdk的安装路径，然后点击确定保存。 #####

## 第四步：配置path ##

在系统变量中选中**path**点击**编辑**，然后在最前面添加：*%JAVA\_HOME%\\bin;%JAVA\_HOME%\\jre\\bin;* 记得后面要加分号，里面的JAVA\_HOME指向上一步配置的内容。

## 第无步：配置CLASSPATH ##

在系统变量中点击新建按钮，变量名设置为：**CLASSPATH**  
变量值设置为：*.;%JAVA\_HOME%/lib/dt.jar;%JAVA\_HOME%/lib/tools.jar;* 即可。
