### Question:
CSN implements Serializable, Comparable<CSN> { @Override public int hashCode() { return this.seqnum + this.serverId + Long.valueOf(timeStamp).hashCode(); } CSN(String str);  CSN(long timeStamp, int seqNum, int serverId); static CSN valueOf(String s); static CSN valueOf(ByteSequence bs); long getTime(); long getTimeSec(); int getSeqnum(); int getServerId(); @Override boolean equals(Object obj); @Override int hashCode(); ByteString toByteString(); void toByteString(ByteStringBuilder builder); @Override String toString(); String toStringUI(); static int compare(CSN csn1, CSN csn2); static int diffSeqNum(CSN csn1, CSN csn2); boolean isOlderThan(CSN csn); boolean isOlderThanOrEqualTo(CSN csn); boolean isNewerThanOrEqualTo(CSN csn); boolean isNewerThan(CSN csn); @Override int compareTo(CSN csn); static final int BYTE_ENCODING_LENGTH; static final int STRING_ENCODING_LENGTH; static final CSN MAX_CSN_VALUE; }### Answer:
@Test(dataProvider = "createCSN") public void csnHashCode(CSN csn1, CSN csn2, CSN csn3, CSN csn4, CSN csn5) throws Exception { assertEquals(csn1.hashCode(), csn2.hashCode()); }
