腾讯面试官问我适配器和桥接器的区别？

// 黑白打印机接口，图形处理系统期望的接口
interface BlackWhitePrinter {
    void printBlackWhite();
}

// 彩色打印机类，现有组件
class ColorPrinter {
    void printColor() {
        System.out.println("Printing in Color");
    }
}

// 适配器类，使彩色打印机可以作为黑白打印机使用
class PrinterAdapter implements BlackWhitePrinter {
    private ColorPrinter colorPrinter;

    public PrinterAdapter(ColorPrinter colorPrinter) {
        this.colorPrinter = colorPrinter;
    }

    @Override
    public void printBlackWhite() {
        // 假设这里进行了颜色转换的逻辑处理
        System.out.println("Converting to Black and White...");
        colorPrinter.printColor();
    }
}

// 客户端代码
BlackWhitePrinter bwPrinter = new PrinterAdapter(new ColorPrinter());
bwPrinter.printBlackWhite();

// 绘图API接口，实现部分的接口
interface DrawAPI {
    void draw();
}

// 抽象部分的基类
abstract class Shape {
    protected DrawAPI drawAPI;

    protected Shape(DrawAPI drawAPI) {
        this.drawAPI = drawAPI;
    }

    public abstract void draw(); // 抽象方法，由子类实现
}

// 具体的抽象部分，扩展了Shape类
class Circle extends Shape {
    private double x, y, radius;

    public Circle(double x, double y, double radius, DrawAPI drawAPI) {
        super(drawAPI);
        this.x = x;
        this.y = y;
        this.radius = radius;
    }

    public void draw() {
        drawAPI.draw(); // 调用实现部分的方法
    }
}

// 具体的实现部分，实现了DrawAPI接口
class OpenGLAPI implements DrawAPI {
    @Override
    public void draw() {
        System.out.println("OpenGL drawing");
    }
}

class VulkanAPI implements DrawAPI {
    @Override
    public void draw() {
        System.out.println("Vulkan drawing");
    }
}

// 客户端代码
Shape openglCircle = new Circle(1, 2, 3, new OpenGLAPI());
Shape vulkanCircle = new Circle(1, 2, 3, new VulkanAPI());

openglCircle.draw();
vulkanCircle.draw();
