### Question:
Bitlist { public boolean getBit(int i) { checkElementIndex(i, size); return data.get(i); } Bitlist(int arraySize, long maxSize);  Bitlist(Bitlist bitlist); private  Bitlist(int size, BitSet data, long maxSize); void setBit(int i); void setBits(int... indexes); boolean getBit(int i); int getBitCount(); boolean intersects(Bitlist other); boolean isSuperSetOf(final Bitlist other); List<Integer> getAllSetBits(); IntStream streamAllSetBits(); void setAllBits(Bitlist other); long getMaxSize(); int getCurrentSize(); @SuppressWarnings("NarrowingCompoundAssignment") Bytes serialize(); static int sszSerializationLength(final int size); static Bitlist fromBytes(Bytes bytes, long maxSize); Bitlist copy(); @Override boolean equals(final Object o); @Override int hashCode(); @Override String toString();  }### Answer:
@Test void initTest() { Bitlist bitlist = create(); assertFalse(bitlist.getBit(0)); assertFalse(bitlist.getBit(9)); }
@Test void setTest() { Bitlist bitlist = create(1, 3, 8); assertFalse(bitlist.getBit(0)); assertTrue(bitlist.getBit(1)); assertTrue(bitlist.getBit(3)); assertFalse(bitlist.getBit(4)); assertTrue(bitlist.getBit(8)); }
