**1 .忽略大小写提示(重要)**  
IDEA默认提示是区分大小写的，比如输入string，不会提示String类；这里设置下  
Editor->General ->Code Completion 把红框里的选项去掉即可

2.**自动导包**

**   ** 默认情况，包括Eclipse 写完类，是需要手工导入包的，不过IDEA提供了自动导包设置  
Editor->general->Auto Import

3.**设置文件编码**  
Editor -> File Encodings 统一全部设置utf-8

4.**设置自动编译**  
在Eclipse里，项目都是自动编译的，IDEA里默认不是，我们需要配置下；  
Build,Execution,Deployment -> Compiler 两个勾选下，设置项目自动编译，包括平行结构的多个模块也自动编译；勾选这两个即可

5.显示行数和方法分隔符![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMzOTE5MTE0_size_16_color_FFFFFF_t_70 4][]

6.内存使用量展示

file->setting->appearance & behaivier -> show memory indicator

7.显示多行tab

File-->Settings-->Editor-->General-->Editor tabs

1.去掉 show tabls in one row

2.tab limits 增加为20个。

8.关闭idea自动更新

File->Settings->Appearance & Behavior->System Settings->Updates下取消Automatically check updates for勾选
