### Question:
Roaring64Bitmap implements Externalizable, LongBitmapDataProvider { public void add(long... dat) { for (long oneLong : dat) { addLong(oneLong); } } Roaring64Bitmap(); void addInt(int x); @Override void addLong(long x); @Override long getLongCardinality(); int getIntCardinality(); @Override long select(final long j); Iterator<Long> iterator(); @Override void forEach(final LongConsumer lc); @Override long rankLong(long id); void or(final Roaring64Bitmap x2); void xor(final Roaring64Bitmap x2); void and(final Roaring64Bitmap x2); void andNot(final Roaring64Bitmap x2); @Override void writeExternal(ObjectOutput out); @Override void readExternal(ObjectInput in); @Override String toString(); @Override LongIterator getLongIterator(); @Override boolean contains(long x); @Override int getSizeInBytes(); @Override long getLongSizeInBytes(); @Override boolean isEmpty(); @Override ImmutableLongBitmapDataProvider limit(long x); boolean runOptimize(); @Override void serialize(DataOutput out); void serialize(ByteBuffer byteBuffer); void deserialize(DataInput in); void deserialize(ByteBuffer in); @Override long serializedSizeInBytes(); void clear(); @Override long[] toArray(); static Roaring64Bitmap bitmapOf(final long... dat); void add(long... dat); void add(final long rangeStart, final long rangeEnd); @Override LongIterator getReverseLongIterator(); @Override void removeLong(long x); @Override void trim(); @Override int hashCode(); @Override boolean equals(Object obj); void flip(final long x); @Override Roaring64Bitmap clone();  }### Answer:
@Test public void testCardinalityAboveIntegerMaxValue_RoaringBitmap() { assertThrows(IllegalArgumentException.class, () -> { RoaringBitmap map = new RoaringBitmap(); map.add(0L, outOfRoaringBitmapRange); }); }
