java寫一個音樂播放器_如何用java做一個音樂播放器

A. java怎麼編寫一個簡單的音樂播放器

首先要在環境電腦中安裝下環境，才能引入javax.sound.sampled.*這個包，一下是用過的代碼
package TheMusic;
import java.io.*;

import javax.sound.sampled.*;

public class Music {

public static void main(String[] args) {

// TODO Auto-generated method stub

//修改你的音樂文件路徑就OK了

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

apw.start();

}

}

在程序中實例化這個類，啟動線程，實例化的時候參照Test修改路徑就OK播放聲音的類
Java代碼

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();

}

}

}

D. 如何用java做一個音樂播放器

E. 用java編寫MP3播放器

作業其實還是自己寫的好。要用到JMF包啊，到網上下載一個JMF包，照著說明安裝上。

F. java，我在寫一個音樂播放器（只播放本地音樂），

請先確定您的音樂鏈接是否有效。操作方法：將您貼到音樂盒中的音樂鏈專接，粘貼到屬IE瀏覽器的地址欄中打開，查看是否能夠收聽;2請確定您添加的音樂鏈接最後三個字母為mp3或wma，如果只是由您自己簡單將網頁名稱修改後粘貼的鏈接，仍然是無效的。並注意最後面的地址不要多復制了一個空格。3在音樂收藏中，點擊您音樂盒中不能收聽音樂的編輯按鈕，核對您所貼到音樂盒中的鏈接是否與您在網頁上找到的一致。4如果您在音樂收藏中點擊單首歌曲可以播放，但添加到播放列表中無法播放，請將此歌曲在播放列表中刪除，再添加一次。為什麼聽不到自己空間里的音樂?請您核實瀏覽器是否安裝了網頁助手之類的插件。該插件若是設置了禁止播放網頁音樂則是無法播放的，請將該屏蔽功能關閉即可。其次請安裝 MediaPlayer 播放軟體後嘗試!且請在「音樂盒」播放列表中注意「更新播放列表」。請您注意測試該歌曲的鏈接是否存在不穩定情況，建議您可以更換其他鏈接嘗試。或者您也可以直接使用音樂庫中的歌曲。其次請在「音樂盒」播放列表中注意「更新播放列表」。

H. java大神求解啊，如何用java編寫一個音樂播放器，然後播放器裡面的歌可以順序播放的。
