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
