Also, consider making the array more specific, something like `array<String>`, or `String[]`. This check looks for `@param` annotations where the type inferred by our type inference engine differs from the declared type. It makes a suggestion as to what type it considers more descriptive. In addition it looks for parameters that have the generic type `array` and suggests a stricter type like `array<String>`. Most often this is a case of a parameter that can be null in addition to its declared types. Loading history...
