Eclipse中Java图形界面添加背景音乐

做法一：

InputStream is =null

AudioStream as = null

is = getClass().getResourceAsStream("a.wav")

try {

as = new AudioStream(is)

} catch (IOException e) {}

AudioPlayer.player.start(as)

此方法将音乐文件放入流中在播放，仅限于Java Application，容易报错，空指针异常，或者是流异常，不推荐。

做法二：

String music = "a.wav"

AudioClip clip = Applet.newAudioClip(getClass().getResource(music))

次方法在Applet中运行没有问题，但是Application中getclass()会返回空指针，导致失败。

推荐做法：

private URL url

private AudioClip ac

File f1 = new File("C:/3.wav")

try {

url= f1.toURL()

} catch (MalformedURLException e) {

// TODO Auto-generated catch block

e.printStackTrace()

}

ac= Applet.newAudioClip(cb1)

ac.play()

public void play(String Filename)

{

try{

// 用输入流打开一音频文件

InputStream in = new FileInputStream(Filename)//FIlename 是你加载的声音文件如(“game.wav”)

// 从输入流中创建一个AudioStream对象

AudioStream as = new AudioStream(in)

AudioPlayer.player.start(as)//用静态成员player.start播放音乐

//AudioPlayer.player.stop(as)//关闭音乐播放

//如果要实现循环播放，则用下面的三句取代上面的“AudioPlayer.player.start(as)”这句

/*AudioData data = as.getData()

ContinuousAudioDataStream gg= new ContinuousAudioDataStream (data)

AudioPlayer.player.start(gg)// Play audio.

*/

//如果要用一个 URL 做为声音流的源(source)，则用下面的代码所示替换输入流来创建声音流：

/*AudioStream as = new AudioStream (url.openStream())

*/

} catch(FileNotFoundException e){

System.out.print("FileNotFoundException ")

} catch(IOException e){

System.out.print("有错误!")

}

}
