Unbelievable!
In Java, one can construct a Collection from Enumeration with a single call. But Enumeration is an obsolete interface, one is supposed to use Iterator. Well, guess what, there is no call to construct a Collection from Iterator. Grrrrr.

We wouldn't want programming to become too easy.

How?
How do you create a Collection from an Enumeration?
Collection isn't instantiable...

OK, not EXACTLY Collection
Shhesh
static ArrayList list(Enumeration e)
Returns an array list containing the elements returned by the specified enumeration in the order they are returned by the enumeration.

Oh, got it.
I didn't realize that Collections had that method. That's a nasty little omission. I guess you could make an object wrapper for Iterator that implemented the Enumeration interface: \npublic IteratorEnumeration implements Enumeration\n{\n private Iterator wrapped = null;\n public IteratorEnumeration(Iterator iter) { this.wrapped = iter; }\n\n public boolean hasMoreElements() { return this.wrapped.hasNext(); }\n public Object nextElement() { return this.wrapped.next(); }\n}\nThen you could do: \nArrayList a = Collections.list(new IteratorEnumeration(myIter));\n Bleh.

Oh yes, lets make another class
Heck lets make a dozen of them. Might as well since that's the only mechanism for extension there is in the silly language.
class class class class class class class class class class class class.
Whee!
Now all it needs is an XML descriptor.

If I ever have to program Java...
... I'm going to point to this forum as evidence that I don't want to do that.

All languages have warts.
Perl, Python, and Smalltalk are no exceptions. Java gets a lot of heat because it's so widespread. It beats the hell out of C++ and VB as far as I'm concerned, and since that's the choice you get in most business environments, I'm more than glad to pick Java.

Oh, its OK
