帮我写一个SOLID原则伪代码示例

好的，以下是一个简单的伪代码示例，展示如何使用SOLID原则来设计一个简单的图形绘制程序：

// 单一职责原则示例

class Rectangle {
    int width;
    int height;

    public void setWidth(int w) {
        width = w;
    }

    public void setHeight(int h) {
        height = h;
    }

    public int getArea() {
        return width * height;
    }
}

class Circle {
    int radius;

    public void setRadius(int r) {
        radius = r;
    }

    public int getArea() {
        return (int) (Math.PI * radius * radius);
    }
}

class GraphicsRenderer {
    public void render(Rectangle r) {
        // 绘制矩形
    }

    public void render(Circle c) {
        // 绘制圆形
    }
}

// 开放封闭原则示例

interface Shape {
    int getArea();
}

class Rectangle implements Shape {
    int width;
    int height;

    public void setWidth(int w) {
        width = w;
    }

    public void setHeight(int h) {
        height = h;
    }

    public int getArea() {
        return width * height;
    }
}

class Circle implements Shape {
    int radius;

    public void setRadius(int r) {
        radius = r;
    }

    public int getArea() {
        return (int) (Math.PI * radius * radius);
    }
}

class GraphicsRenderer {
    public void render(Shape s) {
        // 绘制图形
    }
}

// 里氏替换原则示例

class Square extends Rectangle {
    @Override
    public void setWidth(int w) {
        super.setWidth(w);
        super.setHeight(w);
    }

    @Override
    public void setHeight(int h) {
        super.setWidth(h);
        super.setHeight(h);
    }
}

// 接口隔离原则示例

interface Drawable {
    void draw();
}

interface Scalable {
    void scale(int factor);
}

class Rectangle implements Drawable, Scalable {
    // 实现 draw() 和 scale() 方法
}

class Circle implements Drawable, Scalable {
    // 实现 draw() 和 scale() 方法
}

// 依赖倒置原则示例

interface ShapeRenderer {
    void render(Shape s);
}

class GraphicsRenderer implements ShapeRenderer {
    public void render(Shape s) {
        // 绘制图形
    }
}

class Shape {
    int getArea();
}

class Rectangle implements Shape {
    int width;
    int height;

    public void setWidth(int w) {
        width = w;
    }

    public void setHeight(int h) {
        height = h;
    }

    public int getArea() {
        return width * height;
    }
}

class Circle implements Shape {
    int radius;

    public void setRadius(int r) {
        radius = r;
    }

    public int getArea() {
        return (int) (Math.PI * radius * radius);
    }
}

class Drawing {
    private ShapeRenderer renderer;
    private List<Shape> shapes;

    public Drawing(ShapeRenderer r) {
        renderer = r;
        shapes = new ArrayList<>();
    }

    public void addShape(Shape s) {
        shapes.add(s);
    }

    public void draw() {
        for (Shape s : shapes) {
            renderer.render(s);
        }
    }
}
