Witam, chciałbym żeby po wcisnieciu Button2 kolor JPanelu zmieniał się na dowolny kolor z przedziału ( Kod poniżej ) chciałbym to zrobić na classach takich jak JPanel i Button2, jestem początkującą osobą, więc jeśli ktoś jest chętny pomagać mi w zrozumieniu języka, to bardzo proszę o kontakt.
Klasa Frame
import javax.swing.JFrame;
public class Frame {
public JFrame jframe;
public Button1 button1;
public Button2 button2;
public Button3 button3;
public RenderPanel renderpanel;
public static Frame frame;
public Frame() {
JFrame jframe = new JFrame("Nauka");
jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jframe.setSize(600, 500);
jframe.setLocation(400, 300);
jframe.setResizable(false);
jframe.add(renderpanel = new RenderPanel(button2));
jframe.setVisible(true);
}
public static void main(String[] args) {
frame = new Frame();
}
}
Class'a RenderPanel
import java.awt.Color;

import java.awt.FlowLayout;
import java.awt.Graphics;
import javax.swing.JPanel;

public class RenderPanel extends JPanel

public Button1 button1;
public Button2 button2;
public Button3 button3;
public RenderPanel(){
super.setLayout(new FlowLayout());
super.add(button1 = new Button1());
super.add(button2 = new Button2());
super.add(button3 = new Button3());
super.setComponentOrientation(ComponentOrientation.LEFT_TO_RIGHT);
setBackground(Color.YELLOW);
}
@Override
public void paintComponent(Graphics g)
{
super.paintComponent(g);
//g.fillRect(0, 0, 600, 500);
}
}
Class'a Button2

button2.addActionListener(new ActionListener()
