### Question:
XBee16BitAddress { @Override public int hashCode() { int hash = HASH_SEED; for (byte b:getValue()) hash = hash * (hash + b); return hash; } XBee16BitAddress(int hsb, int lsb);  XBee16BitAddress(byte[] address);  XBee16BitAddress(String address); int getHsb(); int getLsb(); byte[] getValue(); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString(); static final XBee16BitAddress COORDINATOR_ADDRESS; static final XBee16BitAddress BROADCAST_ADDRESS; static final XBee16BitAddress UNKNOWN_ADDRESS; }### Answer:
@Test public final void testHashCodeIsConsistent() { XBee16BitAddress addr = new XBee16BitAddress("0x1234"); int initialHashCode = addr.hashCode(); assertThat("Consistent hashcode test fails", addr.hashCode(), is(equalTo(initialHashCode))); assertThat("Consistent hashcode test fails", addr.hashCode(), is(equalTo(initialHashCode))); }
