如何在Java中播放* .wav循環？

我的代碼如下所示：

public class SoundPlayer implements Runnable{ 
public SoundPlayer(String filename){ 
    is=Main.class.getResourceAsStream("sounds/"+filename); 
} 
@Override 
public void run() { 
    // TODO Auto-generated method stub 
    playSound(); 
} 

public void playSound(){ 
    try { 
     audioStream = AudioSystem.getAudioInputStream(is); 
    } catch (Exception e){ 
     e.printStackTrace(); 
     System.exit(1); 
    } 

    audioFormat = audioStream.getFormat(); 

    DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat); 
    try { 
     sourceLine = (SourceDataLine) AudioSystem.getLine(info); 
     sourceLine.open(audioFormat); 
    } catch (LineUnavailableException e) { 
     e.printStackTrace(); 
     System.exit(1); 
    } catch (Exception e) { 
     e.printStackTrace(); 
     System.exit(1); 
    } 

    sourceLine.start(); 

    int nBytesRead = 0; 
    int bufferSize = audioFormat.getFrameSize() * 
    Math.round(audioFormat.getSampleRate()/10); 
    byte[] abData = new byte[bufferSize]; 
    while (nBytesRead != -1) { 
     try { 
      nBytesRead = audioStream.read(abData, 0, abData.length); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
     if (nBytesRead >= 0) { 
      @SuppressWarnings("unused") 
      int nBytesWritten = sourceLine.write(abData, 0, nBytesRead); 
     } 
     else { 
      audioStream.reset(); //I add this code but didn't effect 
     } 
    } 

    sourceLine.drain(); 
    sourceLine.close(); 
} 


private final int BUFFER_SIZE = 128000; 
private File soundFile; 
private AudioInputStream audioStream; 
private AudioFormat audioFormat; 
private SourceDataLine sourceLine; 
private InputStream is;

請幫助我。

你有什麼錯誤嗎？它似乎在哪裏失敗？ etc ... – RMT

它沒有得到任何錯誤。但是，該代碼沒有循環* .wav文件到達結束時:( – Kenjiro

如果是短聲樣品，請使用Clip。使用loop(int)方法設置要重複多少次。

請參閱an example。

如何設置無限循環？以及如何停止當我完成嗎？因爲這是背景音樂的遊戲，所以我不知道究竟有多少循環我需要：（ – Kenjiro

@Kenjiro：「如何設置無限循環？」1）按照我的JavaDocs提供的'loop（count）'方法的鏈接2）讀取它們，特別是單個參數的描述'count'，以及可能的值是什麼。 –

@鑑天郎：「我完成後怎麼停下來？」您可以嘗試閱讀這些細節手冊。 –

我創建了這個類，在單獨的線程中播放.wav聲音。隨意使用和適應，如果你想：

import java.io.*; 
import javax.sound.sampled.*; 
public class CPSound implements Runnable 
{ 
     String fileLocation = "alarm.wav"; 
     CPSound() 
     { 

     } 
     public void play(String fileName) 
     { 
       Thread t = new Thread(this); 
       fileLocation = fileName; 
       t.start(); 
     } 
    public void run() 
    { 
     playSound(fileLocation); 
    } 
     private void playSound(String fileName) 
     { 
       File soundFile = new File(fileName); 
       AudioInputStream  audioInputStream = null; 
       try 
       { 
         audioInputStream = AudioSystem.getAudioInputStream(soundFile); 
       } 
       catch (Exception e) 
       { 
         e.printStackTrace(); 
       } 
       AudioFormat  audioFormat = audioInputStream.getFormat(); 
       SourceDataLine line = null; 
       DataLine.Info info = new DataLine.Info(SourceDataLine.class,audioFormat); 
       try 
       { 
         line = (SourceDataLine) AudioSystem.getLine(info); 
         line.open(audioFormat); 
       } 
       catch (LineUnavailableException e) 
       { 
         e.printStackTrace(); 
       } 
       catch (Exception e) 
       { 
         e.printStackTrace(); 
       } 
       line.start(); 
       int  nBytesRead = 0; 
       byte[] abData = new byte[128000]; 
       while (nBytesRead != -1) 
       { 
         try 
         { 
           nBytesRead = audioInputStream.read(abData, 0, abData.length); 
         } 
         catch (IOException e) 
         { 
           e.printStackTrace(); 
         } 
         if (nBytesRead >= 0) 
         { 
           int  nBytesWritten = line.write(abData, 0, nBytesRead); 
         } 
       } 
       line.drain(); 
       line.close(); 
     } 
}

乾杯！
