二、IDEA使用详解
1. 下载与安装
idea的下载到官网下载即可，其中旗舰版拥有更实用功能，建议下载。支持使用正版！！！
2. 初始常用配置
配置JDK，首先是配置JDK。打开“File”–>“project setting”，添加本地安装的JDK。（idea自己也会带JDK）
3. 快捷键
快捷键 作用
ctrl+shift+f 搜索用这个就行，相当好用。2019版本好像没了
ctrl+shift+n 搜索类名
shift+shift 搜索任何东西
alt+F7 搜索使用到的地方，好用！
ctrl+alt+b 查找子类或实现方法
ctrl+h 查看继承关系
4. 其他常用技巧：工具栏配置
查看单元测试覆盖率，idea已经集成了coverage,只要点击运行旁边的run with coverage即可查看test类执行的测试覆盖率。
ok，这就是我给大家分享的IntelliJ IDEA激活码（2021年3月11日09:42:00更新），希望能帮到大家哈~~
