适配器模式 35mm接口以及25mm接口USB Type-c接口：lighting接口 分别用类模式和对象模式实现耳机接口的转换

类模式：

1. 创建一个接口类，定义耳机接口的标准方法。

public interface HeadphoneInterface {
    void playMusic();
}

2. 创建两个类，分别表示3.5mm接口和2.5mm接口的耳机，实现接口类中的方法。

public class Headphone3_5mm implements HeadphoneInterface {
    @Override
    public void playMusic() {
        System.out.println("使用3.5mm接口的耳机播放音乐");
    }
}

public class Headphone2_5mm implements HeadphoneInterface {
    @Override
    public void playMusic() {
        System.out.println("使用2.5mm接口的耳机播放音乐");
    }
}

3. 创建一个适配器类，实现接口类，将USB Type-c接口转换为3.5mm接口，实现适配器方法。

public class TypeCto3_5mmAdapter implements HeadphoneInterface {
    private TypeCHeadphone typeCHeadphone;

    public TypeCto3_5mmAdapter(TypeCHeadphone typeCHeadphone) {
        this.typeCHeadphone = typeCHeadphone;
    }

    @Override
    public void playMusic() {
        typeCHeadphone.playMusicViaTypeC();
    }
}

4. 创建一个类，表示USB Type-c接口的耳机，实现自己的方法。

public class TypeCHeadphone {
    public void playMusicViaTypeC() {
        System.out.println("使用USB Type-c接口的耳机播放音乐");
    }
}

5. 创建一个类，表示lighting接口的耳机，实现接口类中的方法。

public class LightingHeadphone implements HeadphoneInterface {
    @Override
    public void playMusic() {
        System.out.println("使用Lighting接口的耳机播放音乐");
    }
}

6. 在客户端代码中，实例化各个类，将耳机接口进行转换。

public class Client {
    public static void main(String[] args) {
        HeadphoneInterface headphone1 = new Headphone3_5mm();
        headphone1.playMusic();

        HeadphoneInterface headphone2 = new Headphone2_5mm();
        headphone2.playMusic();

        TypeCHeadphone typeCHeadphone = new TypeCHeadphone();
        HeadphoneInterface headphone3 = new TypeCto3_5mmAdapter(typeCHeadphone);
        headphone3.playMusic();

        HeadphoneInterface headphone4 = new LightingHeadphone();
        headphone4.playMusic();
    }
}

对象模式：

1. 创建一个接口类，定义耳机接口的标准方法。

public interface HeadphoneInterface {
    void playMusic();
}

2. 创建两个类，分别表示3.5mm接口和2.5mm接口的耳机，实现接口类中的方法。

public class Headphone3_5mm implements HeadphoneInterface {
    @Override
    public void playMusic() {
        System.out.println("使用3.5mm接口的耳机播放音乐");
    }
}

public class Headphone2_5mm implements HeadphoneInterface {
    @Override
    public void playMusic() {
        System.out.println("使用2.5mm接口的耳机播放音乐");
    }
}

3. 创建一个适配器类，实现接口类，将USB Type-c接口转换为3.5mm接口，实现适配器方法。

public class TypeCto3_5mmAdapter implements HeadphoneInterface {
    private TypeCHeadphone typeCHeadphone;

    public TypeCto3_5mmAdapter(TypeCHeadphone typeCHeadphone) {
        this.typeCHeadphone = typeCHeadphone;
    }

    @Override
    public void playMusic() {
        typeCHeadphone.playMusicViaTypeC();
    }
}

4. 创建一个类，表示USB Type-c接口的耳机，实现自己的方法。

public class TypeCHeadphone {
    public void playMusicViaTypeC() {
        System.out.println("使用USB Type-c接口的耳机播放音乐");
    }
}

5. 创建一个类，表示lighting接口的耳机，实现接口类中的方法。

public class LightingHeadphone implements HeadphoneInterface {
    @Override
    public void playMusic() {
        System.out.println("使用Lighting接口的耳机播放音乐");
    }
}

6. 在客户端代码中，实例化各个类，将耳机接口进行转换。

public class Client {
    public static void main(String[] args) {
        HeadphoneInterface headphone1 = new Headphone3_5mm();
        headphone1.playMusic();

        HeadphoneInterface headphone2 = new Headphone2_5mm();
        headphone2.playMusic();

        TypeCHeadphone typeCHeadphone = new TypeCHeadphone();
        HeadphoneInterface headphone3 = new TypeCto3_5mmAdapter(typeCHeadphone);
        headphone3.playMusic();

        HeadphoneInterface headphone4 = new LightingHeadphone();
        headphone4.playMusic();
    }
}
