With the list that is collected from the number of checkboxs checked: (code below)

// Audio files from checkboxs
if (cb.isSelected())
{
  File audio = new File(cb.getActionCommand());
  list.add(audio);  // method to add audio to ListOfFiles
}


How could I mix those files in the arraylist up really good.

you should have already known the answer to that ;) You already use that technique in your existing code.

I thought that was it but I might need to shuffle them a couple of times. I looked at it shuffled once that is why i asked the question. Another dump question i have asked.

bobbit31 answered another question just a little while ago, it would have worked fine, so I gave him this one because of that. I hope that is OK with everyone.
