JFrame window problem

[cyber-noob]

Hi
I have problem with JFrames in Java, the program still has a same background color. Please check the program

class gameFrame extends JFrame implements Runnable { //
    public void run(){
        paintIt p = new paintIt();
        add(p);
    }
    public gameFrame(){
        
        
        
        //paintIt p = new paintIt();
        //add(p);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(1000,1500);
        setTitle("Image test");
        getContentPane().setBackground(Color.WHITE);
        setVisible(true);
    }
}

Any help or suggestions will be appreciated. Thanks in advance

I did not understand paintln object? Is it a JPanel? I think this is repeatedly added to the JFrame's contentPanel. It does not matter what color you set the contentPanel as it will bet you will never see it. I did used one JPanel as an animation panel and then swap images in the same panel rather than creating and adding a bunch of components. Your way seems somewhat inefficient to me and may risk running out of memory. Check your program throughly and if any problems then post back again.

Hey I checked my program again, I have done some modification and posted you the new program. Please analyze my program again. Thanks for the help, hooping you will solve my problem.

class MyTimerActionListener implements ActionListener {
      public void actionPerformed(ActionEvent e) {
          if (!(Player.Y+Player.SizeY+2> 400)){
              Player.CharVel[1] += 2;
          } else {
              Player.CharVel[0] = (Player.CharVel[0]/Player.Friction);
          }
        if (Player.Y+Player.SizeY> 400){
            
            Player.CharVel[1] = -Player.CharVel[1]/2;
            Player.Y = 400-Player.SizeY;
        }
        Player.Y += Player.CharVel[1];
           Player.X += Player.CharVel[0]+Player.CharWalk[0];   
        TestingArea.gf.repaint();   
      }
}
