### Question:
Range implements Iterable<E> { public Range(E element) { this(element, element); } Range(E element);  Range(E first, E last);  Range(E first, E last, IEnumerator<E> enumerator);  Range(Range<E> other); E getFirst(); E getLast(); boolean contains(E element); boolean contains(Range<E> range); boolean containedBy(E first, E last); boolean overlaps(Range<E> range); boolean overlaps(E first, E last); boolean canAdd(Range<E> range); void add(Range<E> range); void merge(Range<E> range); Range<E> remove(E element); Range<E> remove(Range<E> range); Range<E> remove(E first, E last); boolean equals(Object object); int hashCode(); String toString(); @Override Iterator<E> iterator();  }### Answer:
@Test(expected = AssertionFailedException.class) public void testBoundsCheck() { range(0, -1); }
