我用Java写了个倒计时，但在最后想显示图片和声音该怎么做，三四天也没想出来啊，求帮助

package cn.flash023{

import flash.utils.Timer;

import flash.events.TimerEvent;

import flash.text.TextField;

import flash.display.MovieClip;

public class opposeTime {

private var T:Timer;

private var p:uint;

private var total:uint;

private var __txt:TextField;

public function opposeTime(_txt:TextField ,_uint:uint ,_p:uint ):void {

__txt=_txt;

total=_uint;

p=_p;

__txt.text =timeFomat(total);

T=new Timer(1000,total);

T.addEventListener(TimerEvent.TIMER ,onTimeProgress);

T.addEventListener(TimerEvent.TIMER_COMPLETE ,onTimeComplete);

T.start();

}

private function onTimeProgress(_evt:TimerEvent):void {

__txt.text =timeFomat(--total);

}

private function onTimeComplete(_evt:TimerEvent):void {

__txt.text ="时间到！";

var _mc:MovieClip=__txt.parent as MovieClip;

trace(_mc);

_mc.gotoAndStop(p);

}

private function timeFomat(_uint:uint ):String {

var _h:String =("0"+int(_uint/3600)).substr(-2);

var _m:String =("0"+int(_uint%3600/60)).substr(-2);

var _s:String =("0"+int(_uint%3600%60)).substr(-2);

return _h + ":" + _m + ":" + _s;

}

}

}

waptw.com上有一款“桌面计时”软件可以实现！你登陆网站后搜一下就行！
