jLabel Icon Animation Glictching

Question

I'm trying to make the person walk but for some reason when I switch icons the label returns to it's default location for a split second then updates to the where I set the bounds. Extremely annoying, any help is much appreciated. Thank You.

public class Main extends JFrame implements ActionListener{

JLabel x = new JLabel("");

ImageIcon player1 = new ImageIcon("C:\\Users\\Kyle\\Documents\\NetBeansProjects\\Testing52\\src\\testing52\\Player1.png");
ImageIcon player2 = new ImageIcon("C:\\Users\\Kyle\\Documents\\NetBeansProjects\\Testing52\\src\\testing52\\Player2.png");

static int count;

Timer timer;

Main(){

    timer = new Timer(100,this);

    setVisible(true);
    setSize(500,500);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setFocusable(false);
    add(x);

    timer.start();
}

public static void main(String [] args){

    Main main = new Main();    
}

@Override
public void actionPerformed(ActionEvent e) {

    count += 1;

    if(count == 10){
        x.setIcon(player1);
    }
    if(count == 20){
        x.setIcon(player2);
    }

    if(count == 30){           
        count = 0;   
    }

    x.setBounds(0, 0,60,60);
}
}

The setBounds(...) call only works when the layout used is null. Having said that, don't use null layouts (see this), but instead use proper layout managers and component positioning.

Even when the Layout is set to null it still does the same thing – Kyle Longrich Sep 30 '16 at 01:40
@KyleLongrich How did you set the layout to null? – user253751 Sep 30 '16 at 01:40
inside Main(){} before i added it to the frame. "x.setLayout(null);" – Kyle Longrich Sep 30 '16 at 01:41

@KyleLongrich It's not x's layout, it's the frame's layout. – user253751 Sep 30 '16 at 01:42
@KyleLongrich: again, don't use null layouts. What positioning are you trying to achieve? A centering of the image? Also read up on the layout managers since you've much to learn about them -- including that it's the layout manager of the container that matters, not the component. – Hovercraft Full Of Eels Sep 30 '16 at 01:43
@HovercraftFullOfEels I would say, don't use null layouts, unless a null layout is what you want. "Don't use such-and-such" is almost always dogma. – user253751 Sep 30 '16 at 01:44
@HovercraftFullOfEels I'm just trying to make an icon that moves around the frame with a Key Listener. I'm not sure what positioning you would call that. – Kyle Longrich Sep 30 '16 at 01:47
@immibis: agree, but that's why we need to see what he's trying to achieve. GUI's get so wonky if you use null layouts, and usually it's used as a beginner's crutch by folks who simply don't know how to use layout managers. – Hovercraft Full Of Eels Sep 30 '16 at 01:47
@KyleLongrich: OK that might be an indication for using null layouts, one of the few. And don't use KeyListeners for this but rather Key Bindings (Google the tutorial). – Hovercraft Full Of Eels Sep 30 '16 at 01:48
@HovercraftFullOfEels Okay will look into it. Thank You so much. – Kyle Longrich Sep 30 '16 at 01:49
