'*' import

Reports any import statements that cover entire packages ('* imports').

Some coding standards prohibit such import statements.

You can configure IntelliJ IDEA to detect and fix such statements with its Optimize Imports command. Go to Settings | Editor | Code Style | Java | Imports, make sure that the Use single class import option is enabled, and specify values in the Class count to use import with '*' and Names count to use static import with '*' fields. Thus this inspection is mostly useful for offline reporting on code bases that you don't intend to change.
