What's an easy way to test this code?

[twiggy62]

Below is the code I have thus far. I want to be able to test the creation of all objects. What would be the easiest way to do this (using the main)?

// MusicCollection class holds an array of Artist objects and Recording objects
public class MusicCollection {

    private Artist[] artistObjs = new Artist[5];
    private Recording[] recordingObjs = new Recording[5];

    // Artist class, member inner class of the MusicCollection class 
    public class Artist {
    }

    // Recording class holds a single Artist object and an array of Track objects
    public class Recording {

        private Artist artistObj = new Artist();
        private Track[] trackObjs = new Track[5];

        // Track class represents a single piece of music within a Recording object
        public class Track {

            private String trackName;

            public String getTrack() {
                return trackName;
            }
        }
    }

    // Test the creation of all objects
    public static void main(String[] args) {
    }
}

Debug your program in Eclipse IDE and open a window called Variables.

You will see all your variables created there as you move on with your code

hello twiggy62,
all class is inner class excpet MusicCollection.
so, to create all those objects, i feel you need special way to do it.

with MusicCollection, just simply code like:

MusicCollection m = new MusicCollection();

with Artist, it is inner class, so you have to do it like this:

MusicCollection.Artist a = m.new Artist();

the same with Recording

MusicCollection.Recording r= m.new Recording();

and, about Track, it is inner class of inner class , so it should be done like this:

MusicCollection.Recording.Track t=  r.new Track();

below is whole java code, good luck:

// MusicCollection class holds an array of Artist objects and Recording objects
public class MusicCollection {

    private Artist[] artistObjs = new Artist[5];
    private Recording[] recordingObjs = new Recording[5];

    // Artist class, member inner class of the MusicCollection class 
    public class Artist {
    }

    // Recording class holds a single Artist object and an array of Track objects
    public class Recording {

        private Artist artistObj = new Artist();
        private Track[] trackObjs = new Track[5];

        // Track class represents a single piece of music within a Recording object
        public class Track {

            private String trackName;

            public String getTrack() {
                return trackName;
            }
        }
    }

    // Test the creation of all objects
    public static void main(String[] args) {
    	MusicCollection m = new MusicCollection();
    	MusicCollection.Artist a = m.new Artist();
    	MusicCollection.Recording r= m.new Recording();
    	MusicCollection.Recording.Track t=  r.new Track();
    	
    }
}
