Extending enum in java. Can we extend (inherit) an enum type.
extending enums in java is not allowed. As example suppose you have two enums A and B .Y
You can't do the following :

Code:: enum B { } enum A extends enum B { // Define you enum here . }

And in the same time you can't use implements keyword , because B is not an interface ,But if your system need both to be same type , for example if you want to define one function signature to take both enums as parameters you can do it by defining an enum and implementing it in both enums .

Code:: interface enuminterface enum B implements enuminterface { } enum A implements enuminterface { // Define you enum here . }

and your signature will be something like this :

Code:: return type myfunction (enuminterface Enumparam) ;
