create and an enumeration of elements by instanting

You can't instantiate any kind of Enumeration - it's an interface

you must subclass it in order to do instantiating.

class YourEnumeration<E> implements java.util.Enumeration<E> {
      public boolean hasMoreElements() {
            // implement
      }

      public E nextElement() {
            // implement
      }
}

What do you intend to do after instantiating an enumeration? An enumeration is not independent but is dependent over something (like a collection, over which it enumerates).

Thanks object, I am sure you mean something like:
Enumeration e = v.elements() ;

Well i had a method that takes an Enumeration as argument, that is after instantiating the enumeration, i will pass it to
the method i am not supposed to change.

>> that is after instantiating the enumeration,

You will not instantiate it. You will get it from something (like a collection) and then pass it to the method.
