### Question:
CommonHashes { public static IncrementalLongHash crc64() { return Hashes.getIncrementalLong(CrcParameters.CRC64); } private  CommonHashes(); static IncrementalIntHash crc32(); static IncrementalIntHash crc32c(); static IncrementalLongHash crc64(); static StatelessIntHash murmur3_32(); static StatelessIntHash murmur3_32(int seed); static StatefulHash murmur3_128(); static StatefulHash murmur3_128(int seed); static StatelessLongHash sipHash24(); static StatelessLongHash sipHash24(long seedLow, long seedHigh); static StatefulHash md5(); static StatefulHash sha1(); static StatefulHash sha256(); static StatefulHash sha384(); static StatefulHash sha512();  }### Answer:
@Test public void testCrc64() { assertEquals(0x6c40df5f0b497347L, CommonHashes.crc64().calculate(DIGITS)); }
