### Question:
Crc32Util { public static long getCrc32(byte[] b) { CRC32 crc = crc32Provider.get(); crc.reset(); crc.update(b); return crc.getValue(); }  static long getCrc32(byte[] b); static long getCrc32(String str); static void main(String[] args);  }### Answer:
@Test public void testCrc32() { long h = Crc32Util.getCrc32(String.valueOf("256")); ApiLogger.debug("Crc32UtilTest testCrc32 h:" + h); }
