package cn.qwery.oop.animal;

public class Animal {
    String name;
    public void run(){
        System.out.println("跑啊跑");
    }
    public void eat(){
        System.out.println("吃啊吃");
    }
}
class Mammal extends Animal{
    public  void other(){
        this.run();
        this.eat();
    }
    public void taisheng(){
        System.out.println("我是胎生");
    }
    public void main(String[] args){
        other();
        taisheng();
    }
}
             程序无错误，无法执行。  public void main(String[] args）{
                                                        Mammal s = new Mammal();
                                                s.other();
我想他输出                                        s.taisheng();
跑啊跑                                                  }   //不能这样写吗？
吃啊吃
我是胎生
