> Hi Saddy
> I like your name!!! Is it your real name? Here is the truth.
> When you call elements ( ) method on an object of Vector class then the elements ( ) method returns an anonymous class which implements Enumeration interface.Now you must be curious enough to know the declaration of that anonymous class. I have attached the implementation of elements ( ) method of Vector class at the end of this posting. So the code

> Enumeration e = v.elements ( ) ;
> is ok because at run time v.elements ( ) returns an object of a class which implements Enumeration interface. This can be proven by
> System.out.println ( e.getClass().getName ( ) ) ;
> which will print java.util.Vector$1
> Since the anonymous class being used here is the first one used in Vector class , so is its name Vector$1.
