Thread: The button wouldn't show on the panel

My problem is the the Button"test2" in the constructor won't show up. I have no idea what is wrong and there are no error at all.

My Goal is to create serveral classes that represent a part of my GUI, which could be put together in my main class. This is a simplify version of my code and has the exact same problem.
I am sure all I need is a tiny change in my code but I couldn't figure it out. Any help/suggestion will be appreciate.

import java.awt.*;
import javax.swing.*;
 
public class ResPanel extends JPanel{
	public void ResPanel() {
		setSize(100,100);
		setLayout(new FlowLayout());
		setBackground(Color.blue);
        JButton test2 = new JButton("test2");
		add(test2);
	}
 
	public static void main(String[] args) {
 
		JFrame frame = new JFrame();
		JPanel lol = new JPanel();
		JButton test1 = new JButton("test1");
		ResPanel r = new ResPanel();
 
		lol.setLayout(new FlowLayout());
		lol.setBackground(Color.red);
		lol.add(test1);
        lol.add(r);
        frame.add(lol);
        frame.setSize(300,300);
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
}

First of all, thanks for the quick reply.(for a moment I though my post was deleted lol)

I am sorry if I didn't make it clear, but I kinda want to keep a certain "style" for the code.
The new code works perfectly but it won't fit into all my other code unfortunatly.

What I am doing right now is making my own game and my structure of the code is like :
Class "game" that contain the main game/animation screen
class "resource panel" that handle everything about that resouce bar.
class "info panel" ....
etc.
and one last class that contain the frame and the main method which put all the other classes together.
also, to make the GUI looks sensible, I really want to have Panels inside Panels( just like in the code where I add the panel 'r' into panel 'lol' then add 'lol' to the frame.

that's the reason I want to extent Jpanel for my ResPanel, so that I could isolate it from the other code.
Is there really no way to save my original code? I am so close to my goal :<

I hope I am not asking too much, feel free to say how stubborn I am XD

@nggdowt, As an aside, FlowLayout is the default layout of a JPanel, so there isn't a need to set that layout (it doesn't hurt, I am just pointing this out for your benefit).

Add some println's in your methods, in particular near the code where the button that is not visible is added (in other words, in the method that looks like a constructor, hint hint)
