To close a dialog box in Java, particularly when using Swing, you can call the `dispose()` method on the dialog instance. For example, if your dialog variable is named `myDialog`, you would use `myDialog.dispose();` to close it. This method releases all of the native screen resources used by the window, effectively closing the dialog box. It's a straightforward and effective way to programmatically close a dialog window in a Java application.
