### Question:
AuditThreadId implements Comparable<AuditThreadId> { @Override public int compareTo(AuditThreadId auditThreadId) { return this.threadId.compareTo(auditThreadId.getThreadId()); }  @Override int compareTo(AuditThreadId auditThreadId);  }### Answer:
@Test public void testAuditThreadId() { AuditThreadId auditThreadId = new AuditThreadId("threadId", "context", "status", "topicId", "createdDate", "createdTime"); assertEquals("threadId", auditThreadId.getThreadId()); assertEquals("context", auditThreadId.getContext()); assertEquals("status", auditThreadId.getStatus()); assertEquals("topicId", auditThreadId.getTopicId()); assertEquals("createdDate", auditThreadId.getCreatedDate()); assertEquals("createdTime", auditThreadId.getCreatedTime()); int equals = auditThreadId.compareTo(auditThreadId); assertEquals(0, equals); }
