Inspectopedia 2025.2 Help

Class name same as ancestor name

Reports classes that have the same name as one of their superclasses, while their fully qualified names remain different. Such class names may be very confusing.

Example:

package util; abstract class Iterable<T> implements java.lang.Iterable<T> {}

A quick-fix that renames such classes is available only in the editor.
