Read M3U(playlist) file in java

Does anyone know of a java library that would allow me to read m3u files to get the file name and its absolute path as an array ... ?

Clarification: I would like my java program to be able to parse a winamp playlist file (.M3U) to get the name+path of the mp3 files in the playlist

m3u is a regular text file that can be read line by line. Just remember the lines that start with # are comments. Here is a class I made for this very purpose. This class assumes you want only the files on the computer. If you want files on websites you will have to make some minor edits.

package AppPackage;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

/**

public class PlayList {
    List<String> mp3;
    int next;
    public PlayList(File f){
        mp3=new ArrayList<>();
        try (BufferedReader br = new BufferedReader(new FileReader(f))) {
            String line;
            while ((line = br.readLine()) != null) {
               addMP3(line);
            }
        } catch (IOException ex) {
            System.out.println("error is reading the file");
        }
        next=-1;
    }    

    private void addMP3(String line){
        if(line==null)return;
        if(!Character.isUpperCase(line.charAt(0)))return;
        if(line.indexOf(":\\")!=1)return;
        if(line.indexOf(".mp3", line.length()-4)==-1)return;
        mp3.add(line);
    }

    public String getNext(){
        next++;
        if(mp3.size()<=next)next=0;
        return mp3.get(next);
    }
}

Then just call

Playlist = new PlayList(file);

Try my java m3u parser:

Usage:

try{
 M3U_Parser mpt = new M3U_Parser();
 M3UHolder m3hodler = mpt.parseFile(new File("12397709.m3u"));
 for (int n = 0; n < m3hodler.getSize(); n++) {
 System.out.println(m3hodler.getName(n));
 System.out.println(m3hodler.getUrl(n));
 }
}catch(Exception e){
 e.printStackTrace():
}

The project is posted here
