在这里我只给一个大概的类模型,类当中的内容需要你自己去处理了

Class Phone{

private string number;

public bool getPhone(){

~~~~~
}

public bool sendPhone(){
~~~
}
}

class Mobilephone extends Phone implement Moveable{

public bool move(){

}

}

public interface Moveable{
public bool move();
}

class Fixedphone extends Phone{
~~~
}

class Cordlessphone extends Fixedphone{

}
