'clone()' method in non-Cloneable class
Reports classes that override the clone() method but don't implement the Cloneable interface. This usually represents a programming error.
Locating this inspection

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
CloneInNonCloneableClass- 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.
Use the Only warn on 'public' clone methods option to ignore methods that aren't public.
For classes designed to be inherited, you may choose to override clone() and declare it as protected without implementing the Cloneable interface and decide whether to implement the Cloneable interface in subclasses.
