编写测试类，创建一个Fan对象，该对象的速度为3，半径为10

package prog02;

class Fan implements Cloneable{

private int speed = 1;

private double radius = 5.0;

public Fan() {

}

public Fan(int speed,double radius) {

this.speed=speed;

this.radius=radius;

}

public int getSpeed() {

return speed;

}

public void setSpeed(int newSpeed) {

speed = newSpeed;

}

public double getRadius() {

return radius;

}

public void setRadius(double newRadius) {

radius = newRadius;

}

@Override

public String toString() {

return "speed " + speed + "\n"

+ "radius " + radius + "\n";

}

@Override

protected Object clone() throws CloneNotSupportedException {

return super.clone(); //To change body of generated methods, choose Tools | Templates.

}

}

public class Program02 {

public static void main(String[] args) {

Fan fan = new Fan(3,10.0);

System.out.println(fan.toString());

}

}
