菜鸟一枚，麻烦各位前辈帮忙看看这个程序题，万分感谢

//声明能拍照的工具类型
public interface Photographable {
    public void takePhoto();
}
//声明照相机类Camera实现拍照接口
public class Camera implements Photographable {

    @Override
    public void takePhoto() {
        System.out.println(this.getClass().getSimpleName() + " take photo");
    }
}
//声明照手机类 Phone实现拍照接口
public class Phone implements Photographable {

    @Override
    public void takePhoto() {
        System.out.println(this.getClass().getSimpleName() + " take photo");
    }
}
//添加人类
public class Person {
    //照相的功能，用不同的设备去照相
    public void takePhoto(Photographable photo){
        photo.takePhoto();
    }
}
//最后的测试类
public class Test {
   
    public static void main(String[] args){
        Person p = new Person();
        p.takePhoto(new Camera());
        p.takePhoto(new Phone());
    }
}
