How to correct indentation in IntelliJ

Question

How can indentation be automatically (not manually) corrected in IntelliJ?

In Eclipse, it's possible to just highlight the code that needs indenting, right-click, and select Source > Correct indentation.

Is there any method for doing the same thing in IntelliJ?

Answer 1

Code → Reformat Code... (default Ctrl + Alt + L) for the whole file or Code → Auto-Indent Lines (default Ctrl + Alt + I) for the current line or selection.

You can customise the settings for how code is auto-formatted under File → Settings → Editor → Code Style.

To ensure comments are also indented to the same level as the code, you can simply do as follows:

_{(example for JavaScript)}

Answer 2

Just select the code and

• on Windows do Ctrl + Alt + L

• on Linux do Ctrl + Windows Key + Alt + L

• on Mac do CMD + Option + L

Answer 3

Select Java editor settings for Intellij Select values for Tabsize, Indent & Continuation Intent (I choose 4,4 & 4)

Then Ctrl + Alt + L to format your file (or your selection).

Answer 4

In Android Studio this works: Go to File->Settings->Editor->CodeStyle->Java. Under Wrapping and Braces uncheck "Comment at first Column" Then formatting shortcut will indent the comment lines as well.

Answer 5

Ctrl + Alt + L works with Android Studio under xfce4 on Linux. I see that Gnome used to use this shortcut for lock screen, but in Gnome 3 it was changed to Super+L (AKA Windows+L): https://wiki.gnome.org/Design/OS/KeyboardShortcuts

Answer 6

You can also try out Ctrl + Alt + I even though you can also use L as well.

Answer 7

Solution of unchecking comment at first column is partially working, because it works for line comments, but not block comments.

So, with lines like:

/* first line
 * second line
 * ...
 */

or

// line 1
// line 2
// line 3
...

they are indented with "Auto reformat", but lines like:

/* first line
   second line
   ...
 */

the identation will not be fixed.

So you should:

• add * or // before each line of comments
• then uncheck Keep when reformatting -> comment at first column
• and Auto reformat.
