### Question:
Iterators { public static <T> Iterator<T> emptyIterator() { return Collections.<T>emptyList().iterator(); } private  Iterators(); static Iterator<T> emptyIterator(); static Iterable<T> asIterable(Iterator<T> iterator); static List<T> asList(Iterator<? extends T> iterator); static Set<T> asSet(Iterator<? extends T> iterator); static Multiset<T> asMultiset(Iterator<? extends T> iterator); static UnaryFunction<? super Iterable<? extends T>, Iterator<? extends T>> fromIterableToIterator(); static UnaryFunction<? super Iterable<? extends T>, Iterator<? extends T>> fromIterableToIterator(Class<T> ofKlass); static UnaryFunction<Iterable<? extends T>, Iterator<? extends T>> fromIterableToIteratorKeepingNull(); static UnaryFunction<Iterable<? extends T>, Iterator<? extends T>> fromIterableToIteratorKeepingNull(Class<T> ofKlass);  }### Answer:
@Test public void shouldReturnAnIteratorContainingNoElements() { Iterator<Integer> iterator = emptyIterator(); assertThat(iterator.hasNext(), is(false)); }
