### Question:
DefaultPeriodDuration extends DefaultDuration implements PeriodDuration { @Override public InternationalString getDesignator() { return DESIGNATOR; } DefaultPeriodDuration(final InternationalString years, final InternationalString months, final InternationalString weeks, final InternationalString days,
            final InternationalString hours, final InternationalString minutes, final InternationalString seconds);  DefaultPeriodDuration(long durationInMilliSeconds); @Override InternationalString getDesignator(); @Override InternationalString getYears(); @Override InternationalString getMonths(); @Override InternationalString getDays(); @Override InternationalString getTimeIndicator(); @Override InternationalString getHours(); @Override InternationalString getMinutes(); @Override InternationalString getSeconds(); InternationalString getWeek(); @Override long getTimeInMillis(); @Override boolean equals(final Object object); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void testGetDesignator() { InternationalString result = periodDuration1.getDesignator(); assertEquals(periodDuration2.getDesignator(), result); }
