It is confusing to have two or more variables under the same scope that differ only in capitalization. Make sure that both of these follow the casing guide (Google Java Style Guide §5.3) and to be consistent if more than one option is possible.
This checker will only find parameters that differ in capitalization with fields that can be accessed from the parameter’s scope.
Suppress false positives by adding the suppression annotation @SuppressWarnings("InconsistentCapitalization") to the enclosing element.
