java - 操作方法时出现问题 - Java

Question

我正在尝试操作抽象类中的公共(public)方法。 我尝试从扩展另一个抽象类的公共(public)类内部的公共(public)方法内部操作该方法，但编译器给了我:

"non-static method method_name() cannot be referenced from a static context"

我需要什么才能使其运行该方法？

public class Dingo extends Animal
{
    public void act()
    {
      if (kangarooCrossing())
      {
            Weapon.killAnimalMySquare();    //<<<<<<<<<< THE Problematic line
      }

      if(canMove()) 
            move();
      else 
            changeDirection();
    }
    // returns true if a Kangaroo is crossing.
    private boolean kangarooCrossing()
    {
        Actor kangaroo = getOneObjectAtOffset(0, 0, Kangaroo.class);
        if(kangaroo != null) {
            return true;
        }
        else {
            return false;
        }
    }
}

abstract class Weapon  extends Actor
{
    /**Kills an animal that steps on current square*/
     public void killAnimalMySquare()
    {
        Actor animal = getOneObjectAtOffset(0, 0, Animal.class);
        if(animal != null)
            getWorld().removeObject(animal);
    }
    /**returns true if an animal is crossing*/
    public boolean animalCrossing()
    {
         Actor animal = getOneObjectAtOffset(0, 0, Animal.class);
         if(animal != null) 
             return true;
         return false;
    }
}

谢谢!

看来您调用目标方法的方法是静态的。

您需要创建此类的实例并在实例上调用此方法。
