Question

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

Answer 1

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!
