  • At least for an enumeration you can do:

    for ( Foo f : Collections.list( enumeration ) ) {

    I suspect that, despite how much sense it makes, they didn't make the Iterator interface extend Iterable because it would break compatibility with a ton of custom Iterators people have coded in the years since Java 1.2. Java is extremely wary of doing this, even when doing differently (like with generics) winds up causing people pain for years.

    As it is, it's pretty easy to create a wrapper class to do

    • Collections.list( enumeration )
