java如何使用此方法制作声音循环？

我的声音听起来真的很奇怪，你认为有没有一种方法可以循环呢？因为它只播放一次，然后停止。下面是声音的代码：

import java.io.File;
import java.io.IOException;

import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.SourceDataLine;

public class Sound {
private final static int BUFFER_SIZE = 12800000;
private static File soundFile;
private static AudioInputStream audioStream;
private static AudioFormat audioFormat;
private static  SourceDataLine sourceLine;

/**
 * 
 * @param filename the name of the file that is going to be played
 *
 */
public static void playSound(String filename){

    String strFilename = filename;

    try {
        soundFile = new File(strFilename);
    } catch (Exception e) {
        e.printStackTrace();
        System.exit(1);
    }

    try {
        audioStream = AudioSystem.getAudioInputStream(soundFile);
    } 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;
    byte[] abData = new byte[BUFFER_SIZE];
    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);
        }
    }

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

要激活它，我需要：

new Thread(new Runnable() {
          public void run() {
            Sound.playSound("hurt.au");
          }
        }).start();

（如果我只是发出声音。播放声音（“hert.au”）；游戏冻结，因为声音在游戏主线程上播放，所以我将声音放在它自己的线程中以避免游戏冻结）

所以问题是，我如何循环它

有 Java 编程相关的问题?
