Question on homework....

Working on this homework - need to have java when launched the program show=
 the main intro window (which it does show me) and then I need to show the =
welcome page but don't know how to make this appear right after. The last =
step is it has to show me the rules windows but not sure how I tell the sys=
tem the user wants to see the rules.

When I run the batch file the intro window appears for a few seconds but no=
t the other window why is it not picking up???? I don't understand where i=
t is getting the if type==1 ??? where is getting 1 from??? Do I need t=
o create menu to ask for type 1 or 2??? Would really appreciate if someone=
 can clarify why it is not working.....

public class window extends JWindow
{

  ImageIcon imIntro = new ImageIcon("images\\Lintro.jpg");
  ImageIcon imWelcome = new ImageIcon("images\\Welcome.jpg");
  ImageIcon imRules = new ImageIcon("images\\Rules.jpg");
  static Thread t = new Thread();
  static int thread = 0;
  static JButton bouton;
  static int X;
  static int Y;

  /* Parametres du constructeur :
        type: 1-> Intro, 2->rules */

  public window( int X, int Y, int type ) {

    super();
    Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
    setSize(X,Y);
    setLocation( (dim.width - X)/2 , (dim.height - Y)/2);
    setVisible(true);
    Container fen = getContentPane();

    if (type == 1 ) bouton = new JButton(imIntro);
    else bouton = new JButton(imRules);
    bouton.setPreferredSize(new Dimension(X, Y) );
    fen.add(bouton);
    bouton.setVisible(true);

    show();

       if( type == 1 ) { //this is the part I don't know where is it ge=
tting it
        try {
            t.sleep(2000);
            thread = 1;
        }
        catch( java.lang.InterruptedException ex ) {
            JOptionPane.showMessageDialog(null, "error");
            }
        dispose();

    }
    /* If it is the rules - close window when user cliques*/
     
    else {
        bouton.addActionListener( new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                     dispose();
                }
        });
