Hier die Lösung eines Java Entwicklers (Event und Factory basiert):

Code:

public class FindAndKillElefant implements FoundAnimalListener {

  WildLifeFactory factory;

  public static void main(String[] args) {
    factory = WildLifeFactory.getInstance(WildLifeFactory.STARTPoints.NORTH_AFRICA, WildLifeFactory.ENDPoints.SOUTH_AFRICA);

    factory.addAnimalFoundListener(this);

    factory.search();
  }

  public void animalFound(AnimalFoundEvent afe) {
    Animal animal = afe.getFoundAnimal();
    if(animal instanceof Elefant) {

      Elefant elefant = (Elefant) animal;
      ElefantKiller killer = new ElefantKiller(factory);

      boolean isdeath = killer.kill(elefant);
      if(!isdeath) factory.release(elefant);    
      else {
        System.out.println("Du hast gerade einen "+elefant.getWeight()+" KG schweren Elefant getötet!");
        System.exit(0);
      }
    }
  }

  class ElefantKiller extends WildlifeKiller {

    public ElefantKiller(WildLifeFactory factory) {
      super(factory);
    }

    public boolean kill(Animal animal) {
      animal.stopHearth(true);
      return removeAnimalFromWildlifeByAnts(animal);
    }
  }
}
