Idiomatic way to use for-each loop given an iterator?

Question

When the enhanced for loop (foreach loop) was added to Java, it was made to work with a target of either an array or Iterable.

for ( T item : /*         


        

Answer 1

The Apache Commons Collections API has a class called IteratorIterable to do exactly this:

Iterator iter;
for (X item : new IteratorIterable(iter)) {
    ...
}
