使用BufferedReader和BufferedWriter的Java中mp3文件的播放列表

Question

I've been working on a really simple mp3 player in java for some weeks now and I'm wondering if I can do playlist with a BufferedReader and BufferedWriter method. For example with JFileChooser I'd choose song and store its path to file (for example "playlist.txt") and then in while loop ( BufferedReader.available() ) I'd read path and play it. Is this possible? Or Is it better to set chooser.setMultiSelectionEnabled() to true and work in this direction?

Answer 1

Seems like the best solution for this would be making a BufferedReader over the FileReader to read the file. Then you can make java.io.File objects and put those into a java.util.ArrayList . Then you can get the files easily from from the ArrayList and dispose the readers. You can also add an refresh method to refresh the list if needed.

What I did was use a for loop like this:

File playlist = new File("U:\\186Project\\Project\\data");
for(File f : playlist.listFiles()){
  song = minim.loadFile(f.getName(), 2048);
  ......
}

I was using Processing to make LEDs light up to the beat of music, if you want to check out the full code out go here .

This won't let you choose certain songs but it does cycle through them like a playlist. Make sure to change "U:\\186Project\\Project\\data" to whatever directory has all your MP3 files in it.
