本文通过具体实例介绍了Java中接口、抽象类、多态等面向对象编程概念的应用，包括如何实现接口及接口之间的继承，并通过一个简单的多态应用展示了Java面向对象编程的优势。

package test;

interface Dongwu {
void eat();
}

package test;

public class Gou implements Dongwu{
   public void eat() {
       // TODO Auto-generated method stub
       System.out.println("我是小狗");
   }

}

package test;

public class Mao implements Dongwu{

   @Override
   public void eat() {
       // TODO Auto-generated method stub
       System.out.println("我是小猫");
   }

}

package test;

public class ADongwu implements Dongwu{
   private Dongwu dongwu;
   public ADongwu(Dongwu dongwu) {
       // TODO Auto-generated constructor stub
       this.dongwu = dongwu;
   }
   @Override
   public void eat() {
       // TODO Auto-generated method stub
       System.out.println("A家的动物吃饭前要先跑一跑");
       dongwu.eat();
   }

}

package test;

public class BDongwu implements Dongwu{
    private Dongwu dongwu;
   public BDongwu(Dongwu dongwu) {
       // TODO Auto-generated constructor stub
       this.dongwu = dongwu;
   }
   @Override
   public void eat() {
       // TODO Auto-generated method stub
       System.out.println("B家的动物吃饭先要先跳一跳");
       dongwu.eat();
   }

}

package test;

public class Test {
   public static void main(String args []) {
       Gou gou = new Gou();
       ADongwu a = new ADongwu(gou);
       a.eat();

       Gou gou2 = new Gou();
       BDongwu b = new BDongwu(gou2);
       b.eat();
   }
}
