Quick help needed

I am trying to create a game of 'Pig' using a precoded die and gui class (school project), and am getting the following exception:

Exception in thread "main" java.lang.NullPointerException
at java.awt.Container.addImpl(Container.java:1045)
at java.awt.Container.add(Container.java:365)
at GUI.<init>(GUI.java:53)
at GUI.main(GUI.java:37)

It is flagging these lines of code (denoted with '<<<----------'):

 public static void main(String args[]){
        // the traditional five lines of code from the book are
        // provided in the GUI constructor
        new GUI();
    }
    
public GUI(){ <<<---------

    // create the game object as well as the GUI Frame   
    ButtonListener buttonListener= new ButtonListener();
    game = new Pig();
    myGUI = new JFrame();
    myGUI.setSize(400,400);
    myGUI.setTitle("Taylor's Game of Pig");    

    // place the die in the middle of the screen
    JPanel panel = new JPanel();
    d1 = game.getDie(1);
    d2 = game.getDie(2);
    panel.add(d1); <<<-----------
    panel.add(d2);
    myGUI.add(panel);

I am kinda sick of screaming questionable things at my computer, so any help is appreciated.

ps. ready to commence facedesking when I find out it's something really stupid.

d1 is null? So it looks like that getDie(..) returns null. Why? We don`t know, take a look at your Pig class!

Well, thanks for the help, but I think I found the problem:

I misread what was going to what, and it turns out my Pig class needs a complete rewrite.
In other words, PICNIC error: Problem In Chair, Not In Computer.

Cheers!
