java编写一个音乐播放器_如何用java做一个音乐播放器

㈠ java，我在写一个音乐播放器（只播放本地音乐），

请先确定您的音乐链接是否有效。操作方法：将您贴到音乐盒中的音乐链专接，粘贴到属IE浏览器的地址栏中打开，查看是否能够收听;2请确定您添加的音乐链接最后三个字母为mp3或wma，如果只是由您自己简单将网页名称修改后粘贴的链接，仍然是无效的。并注意最后面的地址不要多复制了一个空格。3在音乐收藏中，点击您音乐盒中不能收听音乐的编辑按钮，核对您所贴到音乐盒中的链接是否与您在网页上找到的一致。4如果您在音乐收藏中点击单首歌曲可以播放，但添加到播放列表中无法播放，请将此歌曲在播放列表中删除，再添加一次。为什么听不到自己空间里的音乐?请您核实浏览器是否安装了网页助手之类的插件。该插件若是设置了禁止播放网页音乐则是无法播放的，请将该屏蔽功能关闭即可。其次请安装 MediaPlayer 播放软件后尝试!且请在“音乐盒”播放列表中注意“更新播放列表”。请您注意测试该歌曲的链接是否存在不稳定情况，建议您可以更换其他链接尝试。或者您也可以直接使用音乐库中的歌曲。其次请在“音乐盒”播放列表中注意“更新播放列表”。

㈥ java大神求解啊，如何用java编写一个音乐播放器，然后播放器里面的歌可以顺序播放的。

参考代码如下
首先下载播放mp3的包，比如mp3spi1.9.4.jar。在工程中添加这个包。

㈦如何用Java来编写一个音乐播放器

首先要在环境电脑中安装下JMF环境，才能引入javax.sound.sampled.*这个包，一下是用过的代码
package TheMusic;
import java.io.*;

import javax.sound.sampled.*;

public class Music {

public static void main(String[] args) {

// TODO Auto-generated method stub

//修改你的音乐文件路径就OK了

AePlayWave apw=new AePlayWave("突然好想你.wav");

apw.start();

}

}

在程序中实例化这个类，启动线程，实例化的时候参照Test修改路径就OK播放声音的类
Java代码

public class AePlayWave extends Thread {

private String filename;

public AePlayWave(String wavfile) {

filename = wavfile;

}

public void run() {

File soundFile = new File(filename);

AudioInputStream audioInputStream = null;

try {

audioInputStream = AudioSystem.getAudioInputStream(soundFile);

} catch (Exception e1) {

e1.printStackTrace();

return;

}

AudioFormat format = audioInputStream.getFormat();

SourceDataLine auline = null;

DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);

try {

auline = (SourceDataLine) AudioSystem.getLine(info);

auline.open(format);

} catch (Exception e) {

e.printStackTrace();

return;

}

auline.start();

int nBytesRead = 0;

byte[] abData = new byte[512];

try {

while (nBytesRead != -1) {

nBytesRead = audioInputStream.read(abData, 0, abData.length);

if (nBytesRead >= 0)

auline.write(abData, 0, nBytesRead);

}

} catch (IOException e) {

e.printStackTrace();

return;

} finally {

auline.drain();

auline.close();

}

}

}
