try {
String player=command+" "+command1;
Runtime r = Runtime.getRuntime();
r.exec(player);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
下一段代码
package frame;

import java.util.*;

public class dingshi extends TimerTask{
/**
   * @param args
   */
frame s=new frame();
Timer timer = new Timer();
public void run(){
   //必须要有run方法
s.player();
}
public void start()
{
//一分钟执行一次
timer.scheduleAtFixedRate(this, 1000*s.getResult(), 1000*s.getResult());
}
}
非常感谢！
