Use two threads. One to play the audio and the other to store it in an ArrayList or another collection object.

use one of the list implementation... putting more on the same or playback, you have to implement on your own.
There is no built in support of that in Java as I know

List fifo = Collections.synchronizedList(new ArrayList());


...


public void play() {
      if (fifo.isEmpty() == false) {
            byte[] bytes = (byte[])fifo.remove(0);
            playAudio(bytes);
      }
}      

public void queueForPlayback(byte[] bytes) {
      fifo.add(bytes);
}

Hi!!

Hope you're still there...

Can your FIFO store binary data?

Seems like it don't play back that well... But if I send a file with content:

\x0A, it seems to store and playback well....

>>Can your FIFO store binary data?

Yes, as you can see, i assumed using a byte[]. Playback is another thing of course ...
