Field can be made 'static'

Reports instance variables that can safely be made static. A field can be static if it is declared final and initialized with a constant.

Example:

public final String str = "sample";

Locating this inspection

By ID

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

The inspection does not report final fields that can be implicitly written. Use the "Annotations" button to modify the list of annotations that assume implicit field write.
