修改后重启idea如图：

控制台乱码的解决：

第一步：修改IDEA配置文件
    在idea.exe.vmoptions和idea64.exe.vmoptions两个文件中分别添加：-Dfile.encoding=UTF-8
第二步：修改IDEA设置：
    File-settings-FileEncoding，涉及到编码的地方全都配置成UTF-8
第三步：在部署Tomcat的VM Options项中添加：-Dfile.encoding=UTF-8
第四步：重启

快捷键Ctrl+Shift+A打开如下窗口，搜索set选择SetBackgroud Image

下载该主题
idea更换主题，配置字体

• 主题亮暗设置
  

我们发现在在Setting下修改字符编码为UTF-8以后，再新建项目的编码依然为系统默认System……
File->Other Settings,新建java-04后查看编码发现修改成功。再创建项目默认都是utf-8

需要修改哪部分格式就在下侧效果展示处点击即可

选中代码块与光标所在行颜色如图：

• 点击左下角切换侧边栏
  组合键Alt+对应数字打开侧边栏
  

• main/psvm、sout、… 类中输入main或psvm回车自动补齐主函数，输入sout自动补齐输出语句

• Home 光标移动到所在行的行首（Fn+左键）

• End 光标移动到所在行的行的行尾（Fn+右键）

• F2 快速定位到下一个错误和警告处，加Shift键，定位到上一个错误处

• CTRL+/，CTRL+SHIFT+/ 选中多行后，Ctrl+/可以多个单行注释，或多行注释，若已经注释则取消注释

• CTRL+D 复制当前行数据到下一行

• CTRL+Y或+X或delete 删除光标所在行

• CTRL+ALT+L 格式化代码（自动调整代码格式）

• ALT +SHIFT+↑，ALT +SHIFT+↓ 上下移动当前代码

• Ctrl+Shift+F12 放大窗口或缩小窗口，来回切换

参考自IDEA上安装和使用JetBrains Mono字体（Windows）
下载官网
https://www.jetbrains.com/lp/mono/

• 下载安装包
  
• 解压后安装
  
  -安装后重启idea选择字体
  

参考自idea ：插件Statistic 统计代码数量和行数
-插件功能

显示项目统计数量。
这个插件显示的是按扩展名排序的文件，以及大小、行数、LOC等。
用户可以选择统计(Project/Module/Package/File)范围，选择范围后需要点击Refresh，。
(这个插件需要Java1.8)

file->settings

• 重启idea后使用

1、打开IDEA 菜单 View
2、选择 Tool window
3、点击 Statistic
4、可以看到不同类型文件的统计
5、refresh 重新统计
6、上面的tab 切换可以查看不同类型文件的统计

• 这里出现问题， Tool window中没有Statistic，猜测版本不匹配，我的idea是2018.2.5
  
  

• 在本地文件夹D:MyAllMySofeIntelliJ IDEA2018.2.5IntelliJ IDEA 2018.2.5plugins新建statistic目录，将Statistic-3.4.1.jar下载到该目录：
  
  

• 卸载原最新版本Statistic插件

• 我们在使用idea时经常需要安装及删除插件，下面就介绍一下如何操作。 点击左上【File】后点击【Settings】打开。 在右边【Marketplace】显示所有插件。 点击搜索栏搜索我们要的插件，然后点击【Install】安装。 下载完后需要重启idea，重启完后就可以使用了。 如果要删除插件则切换到【Installed】,右键点击插件，选择【Unstall】就可以了。
  

• 卸载原最新版本Statistic插件 -> 重启IDEA -> File -> Settings -> Plugins -> 点击右上角的设置图标 -> Install Plugin from Disk -> 选择上面下载到本地的插件jar包 -> 重启IDEA
