//下載一個(gè).mid文件命名為1,放在上述代碼的包下
在?applet?中播放聲音文件非常簡(jiǎn)單,一般需要以下步驟:創(chuàng)建一個(gè)?AudioClip?對(duì)象
裝入?.au?聲音文件到?AudioClip?對(duì)象
一次播放或者不停循環(huán)播放聲音
停止播放
下面是相應(yīng)的代碼:import?java.applet.*;AudioClip?ac?=?getAudioClip(getCodeBase(),?soundFile);
ac.play();?//play?once
ac.stop();?//stop?playing
解決這個(gè)問(wèn)題的竅門(mén)是利用由?Sun?及?其JDK?提供的某些?undocumented?的特征。先看看?Sun?JDK?中的文件?classes.zip?(使用任何解壓工具即可),發(fā)現(xiàn)其中不僅包含標(biāo)準(zhǔn)的?Java?包如?java.applet?而且還存在包?sun.audio.?(在?sun/audio?的目錄下.)
包?sun.audio?中包含了用于播放聲音文件所需的所有東西!下面是示例代碼:import?sun.audio.*;?//import?the?sun.audio?package
import?java.io.*;//**?add?this?into?your?application?code?as?appropriate//?Open?an?input?stream?to?the?audio?file.
InputStream?in?=?new?FileInputStream(Filename);//?Create?an?AudioStream?object?from?the?input?stream.
AudioStream?as?=?new?AudioStream(in);//?Use?the?static?class?member?"player"?from?class?AudioPlayer?to?play
//?clip.
AudioPlayer.player.start(as);//?Similarly,?to?stop?the?audio.
AudioPlayer.player.stop(as);如果要用一個(gè)?URL?做為聲音流的源(source),則用下面的代碼所示替換輸入流來(lái)創(chuàng)建聲音流:AudioStream?as?=?new?AudioStream?(url.openStream());如果需要持續(xù)播放聲音文件,則要稍稍復(fù)雜一點(diǎn)://?Create?audio?stream?as?discussed?previously.
//?Create?AudioData?source.
AudioData?data?=?as.getData();//?Create?ContinuousAudioDataStream.
ContinuousAudioDataStream?cas?=?new?ContinuousAudioDataStream?(data);//?Play?audio.
