i want write 2d java game

If you can remove lines of code that cause errors and still have the program do what you want,
then that should work.

i skip that part. i want show score on screen. how do i do that?

[Norm]

Add some JLabels and set their text.
Add some code to the paint method and use drawString.

i write this, but not print anything

string=Integer.toString(s);
        
        g.drawString(string, 0, 0);

i try this also,

JLabel label = new JLabel();
    	label.setBounds(0, 0, 50, 100);
    	label.setText(score);
    	add(label);

can i change color of the text?

Call the Graphics class's setColor method before calling the drawString method.

Try changing the x,y locations to many different values until you see where it is drawing the String.
