### Question:
Convert { public static byte[] toPartialHash(byte[] hash) { Objects.requireNonNull(hash, "Hash should not be null"); if (hash.length != 32) { throw new IllegalArgumentException("Invalid hash length"); } return Arrays.copyOfRange(hash, 8, hash.length); } private  Convert(); static byte[] parseHexString(String hex); static long getId(byte[] publicKey); static String toHexString(byte[] bytes); static long parseUnsignedLong(String number); static long parseLong(String s); static long parseLong(Object o); static long parseAccountId(String account); static byte[] longToBytes(long l); static byte[] concat(byte[]... arrs); static byte[] reverse(byte[] bytes); static byte[] toFullHash(long id, byte[] partialHash); static byte[] reverseSelf(byte[] bytes); static long bytesToLong(byte[] b); static String defaultRsAccount(long accountId); static long fullHashToId(byte[] hash); static byte[] toPartialHash(byte[] hash); static String emptyToNull(String s); static String nullToEmpty(String s); static byte[] emptyToNull(byte[] bytes); static byte[][] nullToEmpty(byte[][] bytes); static long[] nullToEmpty(long[] array); static long nullToZero(Long l); static long[] toArray(List<Long> list); static List<Long> toList(long[] array); static Long[] toArray(long[] array); static Integer[] toArray(int[] array); static Long[] toObjectLongArray(List<Long> longs); static Integer[] toObjectIntArray(List<Integer> integers); static long[] toArray(Long[] array); static int[] toArrayInt(Integer[] array); static Set<Long> toSet(long[] array); static byte[] toBytes(String s); static byte[] toBytes(String s, boolean isText); static String toString(byte[] bytes); static String toString(byte[] bytes, boolean isText); static byte[] toBytes(long n); static String readString(ByteBuffer buffer, int numBytes, int maxLength); static String truncate(String s, String replaceNull, int limit, boolean dots); static long parseStringFraction(String value, int decimals, long maxValue); static byte[] compress(byte[] bytes); static byte[] uncompress(byte[] bytes); static final BigInteger two64; static final long[] EMPTY_LONG; static final int[] EMPTY_INT; static final Long[] EMPTY_OBJECT_LONG; static final Integer[] EMPTY_OBJECT_INT; static final byte[] EMPTY_BYTE; static final byte[][] EMPTY_BYTES; static final String[] EMPTY_STRING; static final Comparator<byte[]> byteArrayComparator; }### Answer:
@Test void testToPartialHash() { byte[] partialHash = Convert.toPartialHash(HASH); assertArrayEquals(PARTIAL_HASH, partialHash); }
