Without posting your code it's hard to guess how your program should work

Without posting your code it's hard to guess how your program should work

myPanle class

public class CustomPanel extends JPanel {

JButton ml = new JButton("my");

    @Override
    public Component add(Component comp) {
        return super.add(ml);
    }
}

main class & form

public class Main  {
    public static void main(String[] args) {
      JFrame window = new JFrame();
      CustomPanel m = new CustomPanel();
      JPanel myPan = new JPanel();
      myPan = m ;
		window.setSize(700, 700);
		window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		window.add(myPan);
		window.setVisible(true);
	}
    }

why components of custompanl not appear in mypan ?

You should probably try adding the CustomPanel instance to the new panel, in your case the instance is myPan.

myPan = m;

Just copies the reference of m to myPan, right now you adding both panels to the frame.

myPan.add(m);

might work

Then add myPan to the frame so

window.add(myPan);
