Alarm extends io.github.amyassist.amy.utility.rest.Entity implements RegistryEntity { public static boolean timeValid(int hour, int minute) { return hour <= 23 && hour >= 0 && minute <= 59 && minute >= 0; } Alarm();  Alarm(int id, LocalDateTime alarmTime, boolean active); @Override String toString(); static boolean timeValid(int hour, int minute); int getId(); void setId(int id); LocalDateTime getAlarmTime(); boolean isActive(); void setActive(boolean active); @Override int getPersistentId(); @Override int hashCode(); @Override boolean equals(Object obj); void setAlarmTime(LocalDateTime alarmTime);  }### Answer:
@Test public void timeValidTest() { assertFalse(Alarm.timeValid(-1, 0)); assertFalse(Alarm.timeValid(0, -1)); assertFalse(Alarm.timeValid(-1, -1)); }
