Can you inherit from enum, i.e., extend enum?

In Java, you cannot create a class that inherits from enum (i.e., extends enum is impossible). An enum in Java is a special type that does not support inheritance because all enum elements are a fixed set of constants defined within the enum class itself.

If you need to extend the functionality of an enum, you can use interfaces that the enum can implement, or add methods and fields within the enum itself. But inheritance from enum is not provided by the language.
