How to surround code by curly braces in IntelliJ I

问题:

How to surround code by curly braces in IntelliJ IDEA? Is there any keyboard-shortcut for such operation?

回答1:

Yes, try Ctrl+Alt+T (Surround With), then A (Curly Braces).

回答2:

Just configure Smart Keys as follow:
IDE Settings > Editor > General > Smart Keys > Surround selection on typing quote or brace.

From the IntelliJ built-in help:

If this check box is selected, the selected text on typing a quote, double-quote or brace, will be surrounded with these characters.

If this check box is not selected, then the typed quotes, double-quotes or braces will replace the selection.

Add "Control flow statement without braces" to inspection settings. Then run inspection, select them in the list and then select "Apply Fix 'Add braces'".

It just saved me a whole days tedious work!

回答4:

Just click as the below 2 steps

1, CTRL + ALT + T
2, then press ALT + A at the same time.

Hope to help you.

I had oneline if statement without curly braces and I had to update it with braces in whole file. So I updated code style to always add braces for if/else statement. In Idea go to:

Settings -> Editor -> Code Style -> Java -> Wrapping and Braces (tab)

Find "'If()' Statement"/"Force braces" and change value from "Do not force"(default) to "Always". Press ctrl + alt + L to reformat your file and curly braces would be added. settings
