编写一个名为Fan的风扇类
// Fan.java

}

this.speed = speed;
System.out.println( "set speed: " + speed );
}
public void setOn(boolean on){
this.on = on;
System.out.println( "set on: " + on );
}
public double getSpeed(){
return this.speed;
}
public double getRadius(){

return this.on;
}
public static long getNumOfFan(){
return numOfFan;
}
public String toString(){
return "Fan(speed: " + speed + ", radius: " + radius + ", on: " + on + ")";
}
}
// FanDemo.java
import java.util.*;

{
public static void main(String[] args)

用java实现一个风扇的转动，具体代码如下，可是运行却不转动，请高手帮帮忙
class FengS
{
int fd = 0;
int ft = 0;
FengS(int d, int t)
{
this.fd = d;
this.ft = t;
}
void run()
{
if(fd == 0)
{
System.out.println("风扇停止运行");
}
else if (fd == 1)
{
System.out.println("风扇一档运行");
}
else if (fd == 2)
{
System.out.println("风扇二档运行");
}
else if (fd == 3)
{
System.out.println("风扇三档运行");
}
else
System.out.println("风扇档数出错");
}
void tRun()
{
if (ft == -1)
{
this.run();
}
else if(60= ft ft 0)
{
for (int a = 0; aft ; )
{
this.run();
System.out.println("剩余时间："+ft+"分");
ft--;
}
System.out.println("风扇停止运行");
}
else if (ft == 0)
{
System.out.println("风扇停止运行");
}
else
System.out.println("风扇定时出错");
}
}
class Feng
{
public static void main(String[] args)
{
FengS fs = new FengS(3,60);
fs.tRun();
}
}
求高手给我编译 java 点击一个按钮风扇就转的
上面的那位代码是正常的，只是他用了过期的API而产生了警告。
如果你不想要警告，我就给你改一下了，没有用线程的过期API而是使用正常判断
