### Question:
DefaultOrdinalReferenceSystem extends DefaultTemporalReferenceSystem implements OrdinalReferenceSystem { @Override public String toString() { StringBuilder s = new StringBuilder(super.toString()).append('\n').append("OrdinalReferenceSystem:").append('\n'); if (ordinalEraSequence != null) { s.append("ordinalEraSequence:").append(ordinalEraSequence).append('\n'); } return super.toString().concat("\n").concat(s.toString()); } DefaultOrdinalReferenceSystem(Map<String, ?> properties, Collection<OrdinalEra> ordinalEraSequence); private  DefaultOrdinalReferenceSystem();  DefaultOrdinalReferenceSystem(final OrdinalReferenceSystem object); static DefaultOrdinalReferenceSystem castOrCopy(final OrdinalReferenceSystem object); @Override @XmlElement(name = "component", required = true) Collection<OrdinalEra> getComponents(); @Override boolean equals(Object object, ComparisonMode mode); @Override String toString();  }### Answer:
@Test public void testToString() { String result = ordinalReferenceSystem1.toString(); assertFalse(ordinalReferenceSystem2.toString().equals(result)); }
