### Question:
EthiopianCalendar extends ChronologyBasedCalendar { @Override public int daysInYear( int year ) { return 12 * 30; } protected  EthiopianCalendar(); static Calendar getInstance(); @Override String name(); @Override DateTimeUnit toIso( DateTimeUnit dateTimeUnit ); @Override DateTimeUnit fromIso( Date date ); @Override DateTimeUnit fromIso( DateTimeUnit dateTimeUnit ); @Override DateTimeUnit plusDays( DateTimeUnit dateTimeUnit, int days ); @Override DateTimeUnit minusDays( DateTimeUnit dateTimeUnit, int days ); @Override DateTimeUnit plusWeeks( DateTimeUnit dateTimeUnit, int weeks ); @Override DateTimeUnit minusWeeks( DateTimeUnit dateTimeUnit, int weeks ); @Override DateTimeUnit plusMonths( DateTimeUnit dateTimeUnit, int months ); @Override DateTimeUnit minusMonths( DateTimeUnit dateTimeUnit, int months ); @Override DateTimeUnit plusYears( DateTimeUnit dateTimeUnit, int years ); @Override DateTimeUnit minusYears( DateTimeUnit dateTimeUnit, int years ); @Override int daysInYear( int year ); @Override int daysInMonth( int year, int month ); @Override int daysInWeek(); @Override DateTimeUnit isoStartOfYear( int year );  }### Answer:
@Test public void testDaysInYear() { int daysInYear = calendar.daysInYear( 2006 ); assertEquals( 12 * 30, daysInYear ); }
