fandemo.java

Java 程序设计源码 只提供了部分

class Fan {
	private int speed = 0;
	private boolean on = false;
	private double radius = 50;

	public Fan(int speed, boolean on, double radius) {
		this.speed = speed;
		this.on = on;
		this.radius = radius;
	}
	
	public void setSpeed(int speed) {
		this.speed = speed;
	}

	public void setOn(boolean on) {
		this.on = on;
	}

	public int getSpeed() {
		return speed;
	}	

	public boolean getOn() {
		return on;
	}

	public double getRadius() {
		return radius;
	}
}

public class FanDemo {
	public static void main(String[] args) {
		Fan f = new Fan(0,false,50.0);
		
		f.setSpeed(60);
		f.setOn(true);

		System.out.println(f.getSpeed());
