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:
class Foo {
Foo(Object o) {}
void bar(final Object o) {
new Foo(o);
}
}
After the quick-fix is applied:
class Foo {
Foo(Object o) {}
void bar(Object o) {
new Foo(o);
}
}

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
UnnecessaryFinalOnLocalVariableOrParameter
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.
Here you can find the description of settings available for the Unnecessary 'final' on local variable or parameter inspection, and the reference of their default values.
