<syntaxhighlight lang="java">
SwingWorker<Document, Void> worker = new SwingWorker<Document, Void>() {
    public Document doInBackground() throws IOException {
        return loadXML(); // heavy task
    }
    
    public void done() {
        try {
            Document doc = get();
            display(doc);
        } catch (Exception ex) {

If you use [[Groovy (programming language)|Groovy]] and <code>groovy.swing.SwingBuilder</code>, you can use <code>doLater()</code>, <code>doOutside()</code>, and <code>edt()</code>. Then you can write it more simply like this:

<syntaxhighlight lang="groovy">
doOutside {
    def doc = loadXML() // heavy task
    edt { display(doc) }
}
</syntaxhighlight>
