Как можно использовать два метода из двух разных моделей?

Question

У меня жесткая проблема с моим проектом.Это трудно объяснить.У меня есть две разные модели, но я должен сравнить эти две модели.Должен ли я сделать новую модель для этих двух моделей?

Вот Cart.java.Существует Voyage.java как Model.Этот класс различают, если type_voyage не equals друг друга.У меня есть другая модель с именем Bus.java.Я должен сравнить, если он равен вместе с моделью.

Cart.java

 boolean cartContainsDifferentTypeVoyage(final String type_voyage) {
    ArrayList<Voyage> list = Lists.newArrayList(Collections2.filter(voyages, new Predicate<Voyage>() {
        @Override
        public boolean apply(Voyage voyage) {
            return !voyage.getType_voyage().equals(type_voyage);
        }
    }));
    return list.size() > 0 ? true : false;
}

Bus.java

Answer 1

Когда вы удаляете весь код из вашего вопроса, который является лишним, это делает проблему более очевидной.

Сначала я упростил ваш метод сравнения:

Cart.java

 boolean cartContainsDifferentTypeVoyage(final String type_voyage) {
    for(Voyage voyage : voyages) {
         if(!type_voyage.equals(voyage.getType_voyage()) {
              return true;
         }
    }
}

Затем создал интерфейс

 interface Voyage {
      String getType_voyage();
 }

Bus.java

 public class Bus implements Voyage {
     ...
     private String type_voyage;

     @Override
     public String getType_voyage() {
       return type_voyage;
     }

      ...

}

И изменил Voyage.java на Ferry.java

public class Ferry implements Voyage {
  ...

  private String type_voyage;

  ...

  @Override
  public String getType_voyage() {
      return type_voyage;
  }

  ...

}

Возможно, вы захотите взглянуть на создание еще нескольких классов, чтобы ваши «модельные» классы не выполняли слишком много / не имели так много обязанностей.
