How do I call the implementation of generic enumeration in Java?

I'm trying to pass an enumeration to a method, iterate over the enumerated values, and call the methods that the enumeration implements on all these values I encountered a compiler error in the "value. Getalias()" section It says "method getalias () is not defined as type e." I try to show that e implements the hasalias interface, but it doesn't seem to work This is possible. If so, how can I fix the following code to do what I want? The following code is just to show my process. I'm not going to print the name of the value in the enumeration, but to prove my problem

public interface HasAlias{ String getAlias(); };

public enum Letters implements HasAlias
{
   A("The letter A"),B("The letter B");

   private final String alias;

   public String getAlias(){return alias;}

   public Letters(String alias)
   {
     this.alias = alias;
   }

}

public enum Numbers implements HasAlias
{
   ONE("The number one"),TWO("The number two");

   private final String alias;

   public String getAlias(){return alias;}

   public Letters(String alias)
   {
     this.alias = alias;
   }

}

public class Identifier
{
   public <E extends Enum<? extends HasAlias>> void identify(Class<E> enumClass)
   {
      for(E value : enumClass.getEnumConstants())
      {
         System.out.println(value.getAlias());
      }
   }
}

Solution

The following is how to bind a type to an enumeration that implements hasalias:

<E extends Enum<E> & HasAlias>

Once you change, the rest will do
