public class MusicApp
{
public static void main(String[] args)
{Artist[] myArtists = new Artist[1];
Albums[] myAlbums = new Albums[2];
Songs[] mySongs = new Songs[12];
int s=0, al=0, ar=0, count=0;
try
{
String line = "";
BufferedReader in = new BufferedReader(new FileReader("small list.csv"));
while (((line = in.readLine()) != null) && (count<23))
{
String[] fields = line.split(",");
{
if (fields[0]=="")

int trackNumber = Integer.parseInt(fields[4]);
String trackName = fields[5];
mySongs[s] = new Songs(trackName, trackNumber);
