Java - Can enum in a parameter of an abstract method -

i not familiar enum , want ask whether can put enum in abstract method , override in other class? here example working with:

i have many subclasses extend abstract class, each have own sub command enum type. enum type has int id , string name.

also, method takes sub command , change input ui base on selected sub command.

public class commandone extends commandclass{     ........      public void updateuibysubcmd(subcommand subcmd){           /*do something*/     }      private enum subcommand{         subcmd1    (id1, name1),         subcmd2    (id2, name2),         ........     } } 

i have abstract class extended above subclass, not consist enum couple function override subclass.

the question is, can following , have method updateuibysubcmd become abstract enum type? if allowed, how accomplish it?

public abstract class commandclass{ ..........     public abstract void updateuibysubcmd(enum x); } 

sounds you're looking this:

public abstract class commandclass<e extends enum<e>> { ..........     public abstract void updateuibysubcmd(e x); }  public class commandone extends commandclass<subcommand> {     ........      @override     public void updateuibysubcmd(subcommand subcmd){           /*do something*/     } }  public enum subcommand {     subcmd1    (id1, name1),     subcmd2    (id2, name2),     ........ }
