Hashcode not removing duplicates from set

[Bud Tippins]

I have the following code. Lines 61 through 67 are supposed to be removing the duplicates from the list of titles coming from the file. However when I run this in NetBeans the duplicates appear. What do I need to do to have the duplicates removed?

Thank you for your help.

package jukebox6;

import java.util.*;
import java.io.*;

public class Jukebox6 {
    ArrayList<Song> songList = new ArrayList<Song>();

    public static void main(String[] args) {
        new Jukebox6().go();
    }
    class ArtistCompare implements Comparator<Song> {
        public int compare(Song one, Song two) {
            return one.getArtist().compareTo(two.getArtist());
        }
    }
    class BpmCompare implements Comparator<Song> {
        public int compare(Song one, Song two) {
            return one.getBpm().compareTo(two.getBpm());
        }
    }

    public void go() {
        getSongs();
        System.out.println(songList);
        Collections.sort(songList);
        System.out.println(songList);

        HashSet<Song> songSet = new HashSet<Song>();
        songSet.addAll(songList);

        System.out.println(songList);
    }

    void getSongs() {
        try {
            File file = new File("SongListMore.txt");
            BufferedReader reader = new BufferedReader(new FileReader(file));
            String line = null;
            while ((line = reader.readLine()) != null) {
                addSong(line);
            }
        } catch (Exception ex) { ex.printStackTrace(); }
    }

    void addSong(String lineToParse) {
        String[]tokens = lineToParse.split("/");
        Song nextSong = new Song(tokens[0], tokens[1], tokens[2], tokens[3]);
        songList.add(nextSong);
    }
}

class Song implements Comparable<Song>{
    String title;
    String artist;
    String rating;
    String bpm;
    Integer intRating;
    Integer intBpm;
    
    public boolean equals (Object aSong) {
        Song s = (Song) aSong;
        return getTitle().equals(s.getTitle());
    }

    public int hashCode() {
        return title.hashCode();
    }

    public int compareTo(Song s) {
        return title.compareTo(s.getTitle());
    }

    Song(String t, String a, String r, String b) {
            title = t;
            artist = a;
            rating = r;
            bpm = b;
            intRating = Integer.parseInt(rating);
            intBpm = Integer.parseInt(bpm);
    }

    void makeTitleUpper(String t) {
        t.toUpperCase();
    }

    public String getTitle() {
        return title;
    }

    public String getArtist() {
        return artist;
    }

    public String getRating() {
        return rating;
    }

    public String getBpm() {
        return bpm;
    }

    public String toString() {
        return title;
    }

    public int getIntRating() {
        return Integer.parseInt(rating);
    }

    public int getIntBpm() {
        return Integer.parseInt(bpm);
    }


}

Note that you are printing the songs three times: in lines 25, 27 and 32.

I guess that in line 32 you meant to print songSet, but you are printing songList. You're not printing the content of the HashSet anywhere.

Jesper, Thanks for your help. That was the problem.
