I've tried, and the keyPressed() under KL dosen't seem to be able to call the stuff inside of it.

    public class KL extends KeyAdapter {

        @Override
        public void keyPressed(KeyEvent e) {            
            mario.keyPressed(e);
            int keyCode = e.getKeyCode();
            if(keyCode == KeyEvent.VK_RIGHT){
                System.out.println("VK_Right pressed");
            }
        }

        @Override
        public void keyReleased(KeyEvent e) {
            mario.keyReleased(e);
        }
    }

Do you add mario to KL? If not you will get a null pointer.

I've figured out the problem. I need setFocusable() in my MainConfig constructor after addKeyListener().

    public MainConfig() {
        mario = new Mario();
        this.addKeyListener(new KL());
        this.setFocusable(true);
        System.out.println();
    }

@aazimon
Since the inner class KL isn't static, it "inherits" the members from the parent class.

@SubzeroX5
Yeah I suspected you weren't even getting any events. I didn't know JPanel's were by default non-focusable. I recommend using JComponent instead since those are automatically focusable.
