Unnecessary 'final' on local variable or parameter
Reports local variables or parameters unnecessarily declared final
.
Some coding standards frown upon variables declared final
for reasons of terseness.
Example:
After the quick-fix is applied:
Use the inspection options to toggle the reporting for:
local variables
parameters (including parameters of
catch
blocks and enhancedfor
statements)
Also, you can configure the inspection to only report final
parameters of abstract
or interface methods, which may be considered extra unnecessary as such markings don't affect the implementation of these methods.
Inspection options
Option | Type | Default |
