System.out.println("isValidHeader:: This file starts correctly.");

public static int getNumberOfTracks(String filename)
{
return 0;
}
}
These are codes that I am working with right now. I need help in getNumberOfTracks method where getTotalSeconds should return the total number of seconds listed in the lines of meta-data in the playlist,
or 0 if the file doesn’t exist, or is invalid.
