### Question:
XBee64BitAddress { @Override public int hashCode() { int hash = HASH_SEED; for (byte b:getValue()) hash = hash * (hash + b); return hash; } XBee64BitAddress(byte[] address);  XBee64BitAddress(String address);  XBee64BitAddress(int b0, int b1, int b2, int b3, int b4, int b5, int b6, int b7); byte[] getValue(); String generateDeviceID(); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString(); static final XBee64BitAddress COORDINATOR_ADDRESS; static final XBee64BitAddress BROADCAST_ADDRESS; static final XBee64BitAddress UNKNOWN_ADDRESS; }### Answer:
@Test public final void testHashCodeIsConsistent() { XBee64BitAddress addr = new XBee64BitAddress("0x0013A20040123456"); int initialHashCode = addr.hashCode(); assertThat("Consistent hashcode test fails", addr.hashCode(), is(equalTo(initialHashCode))); assertThat("Consistent hashcode test fails", addr.hashCode(), is(equalTo(initialHashCode))); }
