我有三个类，Organism，Creature和Plant。 Creature和Plant都扩展Organism。现在，当所有内容都捆绑到Organism中时，此代码可以工作，因此我认为GUI类没有问题。基本上，所发生的只是生成了Creature个特定的统计信息，而忽略了Organism个统计信息，返回了0。我找不到任何问题，所以我想你们可以帮忙。 （忽略混乱，我仍在玩耍。）

最佳答案
您必须从Creature.setStats()方法调用super方法
public class Creature extends Organism
public void setStats()
{
super.setStats(); // Call to Organism.setStats()
...
}
....
}
关于java - 扩展类似乎没有继承一些统计信息，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/20748356/
