Java接口调用问题

Question

public class interfaceDemo {
      public static void main(String [] args){
            Eater a = new Eater();
            a.eat(Jing8);
      }
}
abstract class Animal{
      abstract public void cry();
}
class Doy extends Animal{
      public void cry(){
             System.out.println("汪汪汪，，，");
      }
}
class Jing8 extends Doy implements Eatable{
      public void eat(){
               System.out.println("香肉好好吃！");
      }
}
interface Eatable{
      public void eat(); 
}
class Eater{
      public void eat (Eatable p){
                System.out.println("食物准备就绪！");
                p.eat();
      }
}

为什么我调用JIng8的时候，显示出错，a.eat(JIng8);这个语句，Jing8显示出错，怎么改

你没传对象啊，Jin8是类名，应该传一个对象进去，如new Jin8()
