        temp.setBounds((i - 64) * 55, 110, 50, 30);
        add(temp);
    }
    for (int i = 78; i < 91; i++) {

        temp.addActionListener(new BtnListener());
        temp.setBounds((i - 77) * 55, 150, 50, 30);
        add(temp);
    }

    JMenuBar menubar = new JMenuBar();

    JMenuItem newgame = new JMenuItem("New");
    JMenuItem savegame = new JMenuItem("Save Game");
    JMenuItem Loadgame = new JMenuItem("Load");
    JMenuItem exit = new JMenuItem("Exit");

    file.add(savegame);
    file.add(Loadgame);
    file.add(exit);
    file.add(newgame);

    exit.addActionListener(new exitListener());
    JMenu option = new JMenu("Option");
    menubar.add(option);
    JMenuItem op = new JMenuItem("Option");
    option.add(op);
}

class exitListener implements ActionListener {
    public void actionPerformed(ActionEvent arg0) {
        System.exit(0);
    }

class BtnListener implements ActionListener {
    public void actionPerformed(ActionEvent e) {    
        JButton clickedButton = (JButton) e.getSource();
        String text = clickedButton.getText();
        System.out.println(text + lbl);     
        //word.setText(text);
    }

    Properties readfile = new Properties();
    try {
        readfile.load(new FileInputStream("ciu"));
    } catch (Exception e) {
        System.out.println(e.toString());
    }
    for (int i = 1; i <5; i++) {

You have a lot of code not related to your problem. If you want to generate random numbers you can use Random

 Random random = new Random();
 int randomInt = random.nextInt(10);//generate random numbers between 0..10

I'm still not sure what you want here, but I hope this helps

Here is how to read a line from a text file https://stackoverflow.com/a/9181778/1360074

This is how you set text to a label:

JLabel label = new JLabel();
label.setText(str);
