### Question:
LongHashSet extends AbstractSet<Long> implements Serializable { @Override public boolean remove(final Object value) { return value instanceof Long && remove(((Long) value).longValue()); } LongHashSet();  LongHashSet(final int proposedCapacity);  LongHashSet(final int proposedCapacity, final float loadFactor); float loadFactor(); int capacity(); int resizeThreshold(); @Override boolean add(final Long value); boolean add(final long value); @Override boolean remove(final Object value); boolean remove(final long value); void compact(); @Override boolean contains(final Object value); boolean contains(final long value); @Override int size(); @Override boolean isEmpty(); @Override void clear(); @Override boolean addAll(final Collection<? extends Long> coll); @Override boolean removeAll(final Collection<?> coll); @Override LongIterator iterator(); @Override String toString(); @SuppressWarnings("unchecked") @Override T[] toArray(final T[] a); @Override Object[] toArray(); boolean containsAll(final LongHashSet other); @Override boolean equals(final Object other); @Override int hashCode(); static final int DEFAULT_INITIAL_CAPACITY; static final float DEFAULT_LOAD_FACTOR; }### Answer:
@Test public void removingAnElementFromAnEmptyListDoesNothing() { Assert.assertFalse(testSet.remove(0L)); }
