Question

newbie doing Java homework here. I have one class named Album which contains the following constructors:

public class Album {

    private String title;
    private String artist;
    private String genre;
    private Song favoriteTrack;
    private int trackNumber;
    private static int numAlbums;

    //Constructors
    public Album(String title, Song favoriteTrack, int trackNumber) {
        this.title = title;
        this.favoriteTrack = favoriteTrack;
        this.trackNumber = trackNumber;
        artist = favoriteTrack.getArtist();
        genre = favoriteTrack.getGenre();
        numAlbums++;
    }

    public Album(String title, Song favoriteTrack) {
        this(title, favoriteTrack, 1);
    }
...}

And then I have a second class MusicCollection which instantiates the Album class thrice, within its main method…

public static void main (String[] args) {...

    Album album1 = new Album("Debut", "Venus as a Boy", 3);
    Album album2 = new Album("Homework", "Around the World", 7);
    Album album3 = new Album("Ghost in the Machine", "Invisible Sun", 3);
    ...}

However, when I attempt to compile MusicCollection.java, I get the error:

cannot find symbol
symbol : constructor Album(java.lang.String,java.lang.String,int)
location : class Album

for each time I try to call the constructor.
The classes Album and MusicCollection ARE in the same directory, and Album.java compiles.
I imagine I’m doing something silly, but I can’t figure this out.
Any help would be much appreciated!

Answer 1

The second argument of the constructor you defined is Song, not String, but in your main, you try to instantiate it with a String as a second argument.
