java如何读取MP3格式文件的内容然后对其播放实例代码

直接下个JMF，google搜，sun官网上有~~然后安装目录是你的JDK，

再播放MP3文件就：

import javax.media.*;

import java.net.MalformedURLException;

import java.net.URL;

Player player;

File playFile=new File("");//你的MP3文件

try {

player=Manager.createRealizedPlayer(playFile.toURL());

player.prefetch();

player.setMediaTime(new Time(10.0));

player.start();

} catch (NoPlayerException e1)

{

e1.printStackTrace();

} catch (CannotRealizeException e1)

{

e1.printStackTrace();

} catch (MalformedURLException e1)

{

e1.printStackTrace();

} catch (IOException e1)

{

e1.printStackTrace();

}

这种基本代码，自己搜一下，用编译器熟悉熟悉JMF的方法就会了。。。我以前回答别人时的答案～～～

编写一个java类，实现mid或者wav格式的背景音乐播放，要循环的，用作一个小游戏的背景音乐，谢

import java.applet.Applet;

import java.applet.AudioClip;

import java.net.MalformedURLException;

public class MusicAudioClip {

AudioClip clip = null;

public AudioClip getAudioClip() {

return this.clip;

}

public void setAudioClip(AudioClip clip) {

this.clip = clip;

}

public void play() {//播放

if (getAudioClip() != null) {

getAudioClip().play();

}

}

public void loop() {//循环

if (getAudioClip() != null) {

getAudioClip().loop();

}

}

public void stop() {//停止

if (getAudioClip() != null) {

getAudioClip().stop();

}

}

public static void main(String[] args) {

MusicAudioClip mac = new MusicAudioClip();

try {

mac.setAudioClip(Applet

.newAudioClip((new java.io.File("music\\0.wav")).toURL()));//填写你自己的文件路径

} catch (MalformedURLException e) {

e.printStackTrace();

}

mac.loop();//循环播放

}

}

可以用加载声音文件的方法：

第一帧：mysound= new Sound();
