Body
Consider extracting a "actor that play in film" to another class, to decouple film out of actor (actor can also do theathre spectacles, vioce dubbig etc, not specialy movies.) <pre><code>class ActorRole { private Actor actor; private Movie movie; private int dollarsSallary; private int scenesPlayed; // etc. } </code></pre> If you don't want to, I'm almost sure that better create dependency from Movie to Actor than from Actor to Movie, because Movies almost surely have actos: <pre><code>class Movie { private List<Actor> actors = new ArrayList<Actor>(); } </code></pre> This makes harder to count actor statistics (you have to iterate over all Movies) but I think this is a better design. To count single actor shows: <pre><code>for ( Movie movie : listOfAllMovies ) { if ( movie.getActors().contains( myActor ) ) { // read about equals() in Java ! timesPlayed++; } } </code></pre> If you want to make a ranking for more actors, you can use <code>Map<Actor,Integer></code> to map actors to they times played counters. This can be a lengthy operation, so you can think about cashing the results (like in above map) - the solution can be map, ActorStatistics class, simple timesPlayed field in actor etc. etc. Don't be afraid to objects Don't do a hard workaround to mape films to id (like your <code>id</code>, which is propably connected to your film code <code>String</code>, wich add another type-incompatibility issue. Try to use more object references instead of workarounds, and <code>List</code> instead of array. Generally, read about Collections in Java, like <code>ArrayList</code> and <code>HashMap</code> and also overriding <code>equals()</code> and <code>hashCode()</code>, and in general OOP <a href="http://en.wikipedia.org/wiki/Single_responsibility_principle" rel="nofollow">Single responsibility principle</a> and <a href="http://en.wikipedia.org/wiki/Cohesion_%28computer_science%29" rel="nofollow">Class cohesion</a>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
