### Question:
HugeAtomicBitSet { public boolean isEmpty() { for (long wordIndex = 0; wordIndex < bits.size(); wordIndex++) { if (Long.bitCount(bits.get(wordIndex)) > 0) { return false; } } return true; } private  HugeAtomicBitSet(HugeAtomicLongArray bits, long numBits); static HugeAtomicBitSet create(long size, AllocationTracker tracker); boolean get(long index); void set(long index); void set(long startIndex, long endIndex); boolean getAndSet(long index); void flip(long index); long cardinality(); boolean isEmpty(); long capacity(); long size(); void clear(); void clear(long index); BitSet toBitSet();  }### Answer:
@Test void testIsEmpty() { var atomicBitSet = HugeAtomicBitSet.create(42, AllocationTracker.empty()); assertTrue(atomicBitSet.isEmpty()); atomicBitSet.set(23); assertFalse(atomicBitSet.isEmpty()); atomicBitSet.flip(23); assertTrue(atomicBitSet.isEmpty()); }
