### Question:
SchedulePeriod implements ImmutableBean, Comparable<SchedulePeriod>, Serializable { public static SchedulePeriod.Builder builder() { return new SchedulePeriod.Builder(); } private  SchedulePeriod(
      LocalDate startDate,
      LocalDate endDate,
      LocalDate unadjustedStartDate,
      LocalDate unadjustedEndDate); static SchedulePeriod of(
      LocalDate startDate,
      LocalDate endDate,
      LocalDate unadjustedStartDate,
      LocalDate unadjustedEndDate); static SchedulePeriod of(LocalDate startDate, LocalDate endDate); Period length(); int lengthInDays(); double yearFraction(DayCount dayCount, Schedule schedule); boolean isRegular(Frequency frequency, RollConvention rollConvention); boolean contains(LocalDate date); PeriodicSchedule subSchedule(
      Frequency frequency,
      RollConvention rollConvention,
      StubConvention stubConvention,
      BusinessDayAdjustment adjustment); SchedulePeriod toAdjusted(DateAdjuster adjuster); SchedulePeriod toUnadjusted(); @Override int compareTo(SchedulePeriod other); static SchedulePeriod.Meta meta(); static SchedulePeriod.Builder builder(); @Override SchedulePeriod.Meta metaBean(); LocalDate getStartDate(); LocalDate getEndDate(); LocalDate getUnadjustedStartDate(); LocalDate getUnadjustedEndDate(); Builder toBuilder(); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void coverage_builder() { SchedulePeriod.Builder builder = SchedulePeriod.builder(); builder .startDate(JUL_05) .endDate(JUL_18) .unadjustedStartDate(JUL_04) .unadjustedEndDate(JUL_17) .build(); }
