三、配置环境变量

--------------------

为了方便安装，现专门整理安装步骤，按照流程图一步一步执行即可。

## 一、下载 ##

官网下载地址： [https://www.oracle.com/java/technologies/downloads/archive/][https_www.oracle.com_java_technologies_downloads_archive]

以jdk8为例

然后往下滑动，找到Java SE 版本下载链接，我们建议选择Java SE 8 (8U202)以及之前的版本，因为从Java8 202之后的版本就是商业收费的了。

进入后，我们就选择8u202版本，往下滑，找到对应的window安装包

点击进入即可下载，下载之前它会要求你登录，如果没有账号，注册一个即可。登录完成会自动为你进行下载。

## 二、安装 ##

下载下来的安装包，右键已管理员的身份运行。然后按照如下步骤安装即可：

跳出jre安装提示，为避免意外，我们同样选择安装。![0121e288152e4840bd0c1ff3e4179708.png][]

此时安装完成，点击关闭。

## 三、配置环境变量 ##

我们可以选择window任务栏搜索环境变量

或者通过 此电脑 - 右键属性 - 高级系统设置 - 环境变量 的方式进入。

![889f198533fd423bbcb52e54d2f43750.png][]

配置JAVA\_HOME，变量值为我们刚才安装的jdk的bin目录地址。

![715e52eb8c774e08b00f182a4635de18.png][]

![3533ed991ad941928c8a0e4ce1ee25b4.png][]

将Java自动为我们配置的环境变量删掉，我们自己来配置，并上移到第一排。

![2f585e5723f24b7983a592806e9da7b0.png][]

然后点击保存退出即可。

接着打开cmd测试，java -version命令测试，如果出现如下所示及说明配置ok。
