I just figured out that we can do this for exactly the same cost and the intention read a bit more clearly.

for(Enumeration e = foos.getEnumeration(); e.hasMoreElements(); Foo foo = e.nextElement()){
// process foo
}

and a O(1) random access

Method calls are clearly not “1 operation” and furthermore you forget about the item.next() which is called at each loop. Thus, with a collection that has a O(1) get size, the for loop is more efficient than the iterator.
