Unused declaration

Reports unused classes, methods and fields.

Example:

public class Department {
    private Organization myOrganization;
}

Here Department explicitly references Organization but if Department class itself is unused, then inspection would report both classes.

The inspection also reports parameters, which are not used by their methods and all method implementations/overriders, as well as local variables, which are declared but not used.

For more information, see the same inspection in Java.
