Get results and fix problems
If an inspection has detected a problem in your code, you can quickly apply a fix in the editor. Place the caret at the highlighted piece of code and press Alt+Enter.
For some inspections, for example, Assignment used as condition, Unreachable 'case' branch of a 'switch' statement, Assignment used as condition, and others, you can open a preview by pressing Ctrl+Shift+I ().
If you have invoked inspections manually, you can examine the results in the Inspection Results tool window that opens automatically after the analysis is finished. All detected problems are listed in the left part of the tool window. Click a problem to display inspection details on the right.
Apply a quick-fix
To fix a problem, use

Clean up your code
You can streamline the process of fixing problems in your code by running Code Cleanup. This allows you to batch-apply quick-fixes to the selected scope without examining each problem individually.
During the cleanup, the IDE applies fixes from the code cleanup inspections in the selected inspection profile. To view the list of these inspections, open the Settings/Preferences dialog by pressing Ctrl+Alt+S and go to , click 
, and enable the Show only cleanup inspections option.
