Customizing import statements
The options in the
Imports
tab control how
IDEA
manages import statements.
IDEA
can automatically import classes and packages for you, and it can optimize
your import block based on the settings in this tab.
Optimizing imports
You can use the command
Tools | Optimize Imports
(
Ctrl+Alt+O
) to rearrange
your imports as specified in your layout settings. It also removes unused imports
and uses packages instead of single classes if specified in your options. You can
optimize imports from the
Project
