IntelliJ IDEA | Preferences | Code Style

Use this page to choose the code style scheme and change it as required.
Settings of a code style scheme are automatically applied every time IntelliJ IDEA generates,
refactors, or reformats your code.
The code styles are defined at the project level and at the global level.
- Project level
-
Settings at the project level are grouped under the Project scheme, which
is predefined and is marked in bold font. The Project style scheme
applies to the current project only.
If you want to use a different project level scheme, choose the desired scheme and copy its settings to project.
- Global level
-
Settings at the global level are grouped under the predefined Default scheme,
and any other scheme created by the user. The global settings are used
when the user doesn't want to keep code style settings with the project, and share them.
Note
The settings of the predefined schemes cannot be changed! When any modifications are made, IntelliJ IDEA automatically creates a copy of the predefined scheme.
