In Java 5 and above you have the foreach loop, which works magically on anything that implements Iterable:
for (Object o : list) {
doStuff(o);
}
However, Enumerable still does not implement Iterable, meaning that do iterate over an Enumeration you must do the following:
for(; e.hasMoreElements() ;) {
doStuff(e.getNextElement());
}
Does anyone know if there is a reason why Enumeration still does not implement Iterable?
Edit: As a clarification, I'm not talking about the language concept of an enum, I'm talking a Java-specific class in the Java API called 'Enumeration'.
