Inspectopedia 2025.2 Help

Single class import

Reports import statements that import single classes (as opposed to entire packages).

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 and clear the Use single class import checkbox. Thus this inspection is mostly useful for offline reporting on code bases that you don't intend to change.
