Does anyone know the intention of this method? I'm
confused about the role 'end' has. It only affects the
method logic when end == start.
Many Thanks,

static public Collection slice(Collection coll,
int start, int end) {
if(coll == null) {
return null;
}
Iterator iterator = coll.iterator();
Collection sub =
(Collection)ClassUtils.createObject(coll.getClass());
end -= start;
while(iterator.hasNext()) {
if(start == 0) {
if(end == 0) {
break;
} else {
sub.add(iterator.next());
}
} else {
iterator.next(); // ignore
start--;
}
}
return sub;
}
