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();
}
}

Q5: 求高手给我编译 java 点击一个按钮风扇就转的
上面java风扇代码的那位代码是正常java风扇代码的，只是java风扇代码他用java风扇代码了过期的API而产生了警告。
如果你不想要警告，java风扇代码我就给你改一下了，没有用线程的过期API而是使用正常判断
