public class Client {
    public static void main(String[] args) {
        Adaptee adaptee = new Adaptee();
        Target target = new Adapter(adaptee);
        target.sampleOperation1();
        target.sampleOperation2();
    }
}

桥接（Bridge）是用于把抽象化与实现化解耦，使得二者可以独立变化

public intece DrawAPI {
    void drawCircle(int radius, int x, int y);
}

public class GreenCircle implements DrawAPI{

    @Override
    public void drawCircle(int radius, int x, int y) {
        System.out.println("Drawing Circle[ color: green, radius: "
                + radius +", x: " +x+", "+ y +"]");
    }

}

public class RedCircle implements DrawAPI{

    @Override
    public void drawCircle(int radius, int x, int y) {
        System.out.println("Drawing Circle[ color: red, radius: "
                + radius +", x: " +x+", "+ y +"]");
    }

}

public abstract class Shape {
    protected DrawAPI drawAPI;

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

    public abstract void draw();

}

public class Circle extends Shape {
    private int x, y, radius;

    public Circle(int x, int y, int radius, DrawAPI drawAPI) {
        super(drawAPI);
        this.x = x;
        this.y = y;
        this.radius = radius;
    }
    @Override
    public void draw() {
        drawAPI.drawCircle(radius,x,y);
    }
}

public class BridgePatternDemo {
    public static void main(String[] args) {
        Shape redCircle = new Circle(100,100, 10, new RedCircle());
        Shape greenCircle = new Circle(100,100, 10, new GreenCircle());

        redCircle.draw();
        greenCircle.draw();

    }
}
