{
    TextField txtguess;
    Label lblguess, lblenter, lbltitle;
    Image arrow1, arrow2, smile;
    Button btnguess;
    int guesspic, ANSWER, guess;
    public void init ()
    {
        arrow1 = getImage (getCodeBase (),"arrow1.jpg");
        arrow2 = getImage (getCodeBase (),"arrow2.jpg");
        smile = getImage (getCodeBase (), "smile.jpg");

        lbltitle = new Label ("Guess a number between 1and 100");
        lblenter = new Label ("Enter your guess");
        btnguess = new Button ("High or Lower");

        add (btnguess);
        add (lbltitle);
        add (lblenter);
        add (lblguess);
        add (txtguess);


        btnguess.setActionCommand ("High or Lower");
        btnguess.addActionListener (this);

    }


    public void actionPerformed (ActionEvent e)
    {
        String roll = e.getActionCommand ();
        if (roll.equals ("High or Lower"))
        {
            guess = Integer.parseInt (txtguess.getText
                    ());
            static final int ANSWER = (int) (Math.random ()
                    * 100) + 1;

            repaint ();
        }
    }


    public void paint (Graphics g)
    {
        if (guess == ANSWER)
        {
            g.drawImage (smile, 50, 50, 100, 100, this);
            lblguess.setText ("You Got it right");
        }


        else if (guess > ANSWER)
        {
            g.drawImage (arrow1, 50, 50, 100, 100, this);
            lblguess.setText ("You Got it right");
        }


        else if (guess < ANSWER)
        {
            g.drawImage (arrow2, 50, 50, 100, 100, this);
            lblguess.setText ("You Got it right");

it's not suppost to be static :? It's a variable as its value changes :roll:

"static" doesn't mean "constant" in Java.

Rather it means that the variable is only created once for the class, rather than being created for each instance.

well tony was wrong about the static part but what he side was not wrong about the progame. it is  static final int ANSWER

witch means its value can not chage like he side b/c of the final seting.

well at least to my knogale "final" means "constant" in java

if u whont it to all ways be the same, why not make it goable and get ride of the static part?

Definitely try removing the "static".
