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 = 0a<ft )

{

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()

}

}
