I\'m still very new to java programming, so please help me to correct any mistakes I might have overlooked or give tips on how to improve this program.

Okay, so a lo

This works with a mouse click on the menu. You can change it later, to a click on some button or whatever you want.

I added a MouseListener to the Game class. When the user presses the mouse on the menu JPanel, it adds the Pipes JPanel to JFrame and calls the pack method.

Game.java:

import java.awt.Point;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.geom.Rectangle2D;

import javax.swing.JFrame;
import javax.swing.SwingUtilities;
import javax.swing.Timer;

public class Game {

    GameMenu menu = new GameMenu();
    Pipes game;
    boolean start = false;
    JFrame f;
    Rectangle2D menuRect = new Rectangle2D.Double(20, 20, 60, 40);

    public Game() {
        f = new JFrame();

        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.add(menu);
        f.setTitle("Pipe Game");
        f.setResizable(false);
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);



        menu.addMouseListener(new MouseAdapter() {

            @Override
            public void mousePressed(MouseEvent e) {

                Point click = new Point(e.getX(), e.getY());
                System.out.println("Clicked on the Panel");

                if(menuRect.contains(click))
                {
                    System.out.println("Clicked inside the Rectangle.");

                    start = true; 
                    menu.setVisible(false);
                    game = new Pipes();
                    f.add(game);
                    f.pack();

                    Timer timer = new Timer(10, new ActionListener() {  //pipe speed
                        @Override
                        public void actionPerformed(ActionEvent e) {
                            game.move();
                        }
                    });
                    timer.start();

                    Timer refresh = new Timer(30, new ActionListener() {    //refresh rate
                        @Override
                        public void actionPerformed(ActionEvent e) {
                            game.repaint();
                        }
                    });
                    refresh.start();   
                }
            }

            @Override
            public void mouseReleased(MouseEvent e) {
            }
        });

    }

    public static void main(String args[]) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                new Game();
            }
        });
    }
}
