是否可以调用非runnable？

Question

是否有可能以某种方式调用这样的实例？我知道invokeLater需要一个runnable，我可以在该方法中传递一个新实例，但是我需要能够在调用它后访问该实例。

public class Main {

  // Create a new instance of the applet frame
  private static final AppletFrame APPLET_FRAME = new AppletFrame();

  public static void main(String[] args) {
      // Somehow invoke that applet frame without creating a new one here 
      so we can access it later on like below.
      SwingUtilities.invokeLater(APPLET_FRAME);
      // Then if this is possible I can access the invoked instance still.
      // APPLET_FRAME.doSomething();
  }
}
