很多刚刚接触编程的同学，对于编程都是一知半解、很懵懂的状态。
很多同学刚学习 Java 这门编程语言，紧接着自然是在电脑上安装配置相应的编程软件，在这些软件之中最有名的自然就是 IDEA ！
可是又有个问题，从官网下载了 IDEA 的安装包不知道怎么安装 IDEA ？？？
安装了 IDEA 之后又不知道该如何激活！！！
其实这些问题都是非常简单的，今天我就教大家如何安装和激活 IDEA ！
这是我一直在用的激活码，分享给大家：

如果激活码失效了怎么办？永久激活最新版教程 IDEA：http://sigusoft.com/idea/721.html
IDEA安装教程
开始安装Idea，点击next
点击Browse选择好安装文件夹，点击next
根据电脑选择几位，我的电脑是64位选择64bit，Update PATH variable：是否将IDEA启动目录添加到环境变量中，即可以从cmd命令行中启动IDEA，根据需要勾选
点击Install即可，开始安装
安装完成
启动IDEA,选择不导入设置
设置IDEA的UI主题，个人喜欢Darcula主题 ,后期也可以在设置里自行修改，点击Next: Default plugins：
IDEA支持功能插件化。以IntelliJ Platform为基础，添加相应功能的插件后就有了CLion、WebStorm、PyCharm、PHPStorm、Android Studio、GoLand、RubyMine等独立的IDE。对IntelliJ IDEA的插件管理，可以根据开发需求对某些插件开启或关闭。适当地关闭不需要的插件有助于减少占用空间和加快响应速度。初次使用IntelliJ IDEA建议直接点击Next: Featured plugins，上手以后可以在设置的插件管理中进行对插件增删：
IntelliJ IDEA推荐的插件列表，根据自己的需要安装，点击Start using IntelliJ IDEA，启动成功
OK，这时候你的 IDEA 已经安装好啦～～
