Question

this is my attempt at implementing an interface.

im getting the following error

javac MyCollection.java
./au/edu/uow/Collection/DVDAlbum.java:6: cannot find symbol
symbol: class Album
public class DVDAlbum implements Album{

this is the super class

package au.edu.uow.Collection;


public interface Album {

    String getMediaType();

    String getTitle();

    String getGenre();

}

And this is the sub class

public class DVDAlbum implements Album{

    private String Title;
    private String Genre;
    private String Director;
    private String Plot;
    private String MediaType;

    public DVDAlbum(String TempTitle, String TempGenre, String TempDirector, String TempPlot){
        Title = TempTitle;
        Genre = TempGenre;
        Director = TempDirector;
        Plot = TempPlot;
    }
    String getMediaType(){
        return MediaType;
    }
    String getTitle(){
        return Title;
    }
    String getGenre(){
        return Genre;
    }
}

This was the reference i used but its not working for me.

Answer 1

If you aren’t in the same package where the interface is declared, you need to import it:

import au.edu.uow.Collection.Album;

Or use the complete qualified name:

public class DVDAlbum implements au.edu.uow.Collection.Album{ }
