Point well taken, but how do I clone() a Vector<Integer> without a
warning?

new Vector<Integer>(oldVector);

Are you sure you do not want an ArrayList?

Clone is a broken API in the context of Java 1.5, because it actually
mentions Object.

Object was only necessary without generics, now we can use type
parameters.

Angelika Langer has something to say on the matter:
http://www.angelikalanger.com/Gener...ment the clone method of a parameterized type

Cloning is very often not what you want anyway, as it is shallow
copying.

Serialising and deserialising tends to be more thorough, but very
wasteful. I'd rather avoid 'magic' behaviour, and write an explicit
copy constructor or factory method, which is the approach the Java
collections APIs take.

Cheers.
