Is it a deep or a shallow copy?
<p>I'm not sure if the following will result in deep or shallow copy?</p>

<pre><code>public void viewImages(final String[] instancesFilename) {

    String[] instances = (String[])instancesFilename.clone();    
}
</code></pre>

<p>Is there a simple and fast way to deep copy a string array?</p>
