1、定义Handset抽象类，可以设置手机的品牌和型号，info()方法显示手机的品牌和型号的信息，有打电话call()和发短信sendinfo方法。 2、定义Network接口，具备上网的能力。 3、定义PlayWiring接口，具备播放能力。 4、定义TheakePictures接口，具备拍照能力。 4、定义CommonHandset类，继承Handset类的同时实现 PlayWiring接口。 5、定义AptitudeHandset类，继承Handset类的同时实现 Network 和PlayWiring、TheakePictures接口。 6、编写测试类，让普通 手机播放音频、发短信和语音通话，让智能手机上网、播放视频、拍照、发短信和视频通话。

好的，我理解了你的问题。以下是对应的Java代码实现：

Handset抽象类：

public abstract class Handset {
    private String brand;
    private String model;

    public Handset(String brand, String model) {
        this.brand = brand;
        this.model = model;
    }

    public void info() {
        System.out.println("Brand: " + brand + ", Model: " + model);
    }

    public abstract void call(String number);

    public abstract void sendInfo(String info);
}

Network接口：

public interface Network {
    void surfInternet();
}

PlayWiring接口：

public interface PlayWiring {
    void playMusic(String music);
}

TheakePictures接口：

public interface TheakePictures {
    void takePictures();
}

CommonHandset类：

public class CommonHandset extends Handset implements PlayWiring {
    public CommonHandset(String brand, String model) {
        super(brand, model);
    }

    @Override
    public void call(String number) {
        System.out.println("Call " + number);
    }

    @Override
    public void sendInfo(String info) {
        System.out.println("Send info: " + info);
    }

    @Override
    public void playMusic(String music) {
        System.out.println("Play music: " + music);
    }
}

AptitudeHandset类：

public class AptitudeHandset extends Handset implements Network, PlayWiring, TheakePictures {
    public AptitudeHandset(String brand, String model) {
        super(brand, model);
    }

    @Override
    public void call(String number) {
        System.out.println("Call " + number);
    }

    @Override
    public void sendInfo(String info) {
        System.out.println("Send info: " + info);
    }

    @Override
    public void surfInternet() {
        System.out.println("Surfing the Internet...");
    }

    @Override
    public void playMusic(String music) {
        System.out.println("Play music: " + music);
    }

    @Override
    public void takePictures() {
        System.out.println("Taking pictures...");
    }
}

测试类：

public class Test {
    public static void main(String[] args) {
        CommonHandset commonHandset = new CommonHandset("Apple", "iPhone 11");
        commonHandset.info();
        commonHandset.playMusic("Happy Birthday");
        commonHandset.sendInfo("Hello, World!");
        commonHandset.call("123456789");

        AptitudeHandset aptitudeHandset = new AptitudeHandset("Samsung", "Galaxy S21");
        aptitudeHandset.info();
        aptitudeHandset.playMusic("Yesterday Once More");
        aptitudeHandset.sendInfo("Good morning!");
        aptitudeHandset.takePictures();
        aptitudeHandset.surfInternet();
        aptitudeHandset.call("987654321");
    }
}

以上实现了你所描述的要求。
