Java - Object within an Object

so Ive been trying to set values to an object within an object with no luck. This is what I need to do.

Class 1: Interface (main) With MovieDatabase object

Class 2: MovieDatabase with Movie Object

Class 3: Movie with 4 values needed. Name of movie,director etc.

I've previously only used one object and accessed that through another class but I'm not sure how to do this when it's an object within an object. Any examples using the classes above would be appreciated.

A quick example

Movie Class 

public class Movie {


    private String name;
    private String director;


    public Movie(String name,String director){

        this.name=name;
        this.director=director;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getDirector() {
        return director;
    }

    public void setDirector(String director) {
        this.director = director;
    } 

}

MovieDatabase which contains a list of Movie objects

public class MovieDatabase {


    List<Movie> movies = new ArrayList<>();

    public List<Movie> getMovies() {
        return movies;
    }

    public void setMovies(List<Movie> movies) {
        this.movies = movies;
    }


}

Now let's try to create some Movie objects and add them to the list of Movie objects which is a field in MovieDatabase Class

    public class stackoverflow {

        public static void main(String[] args) {
            // TODO code application logic here

            Movie a,b,c,d;
            MovieDatabase db =  new MovieDatabase();


            a = new Movie("Movie1","Director1");
            b = new Movie("Movie2","Director2");
            c = new Movie("Movie3","Director3");
            d = new Movie("Movie4","Director4");

            db.movies.add(a);
            db.movies.add(b);
            db.movies.add(c);
            db.movies.add(d);


            for(Movie movie : db.movies)

 System.out.println("the movie "+movie.getName()+" is directed by "+movie.getDirector());



        }

    }

The output :

the movie Movie1 is directed by Director1

the movie Movie2 is directed by Director2

the movie Movie3 is directed by Director3

the movie Movie4 is directed by Director4
