模拟实现电风扇，可以调3档速度（慢速、中速、快速）；开关按钮；定时吹风；描述风扇的扇叶大小、颜色等。 设计Fan类，属性包括：3个常量SLOW（1）、MEDIUM（2）、FAST（3）代表风扇的速度；1个int属性speed指定速度，默认值为SLOW；1个boolean属性on指定开关机，默认值false；1个double属性radius指定风扇扇叶大小；1个String属性color指定扇叶颜色，默认值为blue。方法包括这些属性的访问器、构造函数、重写Object类的toString()和equals()方法等。修改版本1中Fan类，让其继承Pane类，并且把color属性设置为Color类型，默认属性为red。随机产生radius，取值范围为1-5；随机产生颜色，取值范围为red、blue、yellow、green、orange；根据color、radius属性值绘制风扇。。用javafx写出版本二代码

版本一代码：

    private final int SLOW = 1;
    private final int MEDIUM = 2;
    private final int FAST = 3;
    private int speed = SLOW;
    private boolean on = false;
    private double radius = 5;
    private String color = "blue";

    public Fan() {}

    public int getSpeed() {
        return speed;
    }

    public void setSpeed(int speed) {
        this.speed = speed;
    }

        return on;

    }

                '}';
    }

        return speed == fan.speed &&
                on == fan.on &&
                Double.compare(fan.radius, radius) == 0 &&

    }

    @Override
