### Question:
DefaultTemporalCoordinate extends DefaultTemporalPosition implements TemporalCoordinate { public void setCoordinateValue(final Number coordinateValue) { this.coordinateValue = coordinateValue; } DefaultTemporalCoordinate(final TemporalReferenceSystem frame, final IndeterminateValue indeterminatePosition, final Number coordinateValue); Number getCoordinateValue(); void setCoordinateValue(final Number coordinateValue); @Override boolean equals(final Object object); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void testSetCoordinateValue() { Number result = temporalCoordinate1.getCoordinateValue(); ((DefaultTemporalCoordinate) temporalCoordinate1).setCoordinateValue(250); assertFalse(temporalCoordinate1.getCoordinateValue() == result); }
