+Создайте абстрактный класс животные, содержащие поля location и boundaries. Методы sleep и roam, а также абстрактные методы makeNoize и Eat, классы наследующие класс животное — Lion и Woolf. Оба класса наследника переопределяют методы базового класса. Приведите пример использования классов наследников.
