关于#抽象类#和接口的问题，如何解决？

Question

有同学能帮我看一下我写的有啥问题嘛

题目：利用抽象类和接口知识点编写一个功能

例如 手机 >非智能手机>智能手机

   抽象类的基本属性            手机的基本属性

  抽象类的抽象方法    基本电话功能

接口

         1，有摄像和拍照功能

          2,蓝牙功能

          3，定位功能

代码：package com.dmd;

public abstract class phone {
private String brand;
private int price;

public abstract void call();

public abstract void message();

public phone(String brand, int price) {
    System.out.println("Basic attributes and functions");
    this.brand = brand;
    this.price = price;
    this.call();
    this.message();
}

public interface photograph {
    public void photograph();
}

public interface bluetooth {
    public void bluetooth();
}

public interface location {
    public void location();
}

}

Answer 1

public abstract class phone {
    private String brand;
    private int price;

    public String getBrand() {
        return brand;
    }

    public void setBrand(String brand) {
        this.brand = brand;
    }

    public int getPrice() {
        return price;
    }

    public void setPrice(int price) {
        this.price = price;
    }

    public abstract void call();
    public abstract void message();

}

public interface phoneInterface {
    public void photograph();
    public void bluetooth();
    public void location();

}

public class zhinengPhone extends phone implements phoneInterface {
    @Override
    public void call() {
        System.out.println(this.getBrand()+"打电话功能");
    }

    @Override
    public void message() {
        System.out.println(this.getBrand()+"发短信功能");
    }

    @Override
    public void photograph() {
        System.out.println(this.getBrand()+"拍照功能");
    }

    @Override
    public void bluetooth() {
        System.out.println(this.getBrand()+"蓝牙功能");

    }

    @Override
    public void location() {
        System.out.println(this.getBrand()+"定位功能");

    }

    public static void main(String[] args) {
        zhinengPhone zhinengPhone=new zhinengPhone();
        zhinengPhone.setBrand("华为");
        zhinengPhone.setPrice(8888);
        zhinengPhone.call();
        zhinengPhone.message();
        zhinengPhone.photograph();
        zhinengPhone.location();
        zhinengPhone.bluetooth();
    }
}
