How to make a class run after two buttons are pressed

Question

I am making my first game, and the last time I asked this question, I kinda didn't explain it very well. Basically, below is the opening screen of the game. I know, not very good, but it is just a rough draft. Then I also built the game. There are two buttons in the opening screen, for it is a 2 player game. Both players must click ready, and then I want to program to end, and to start the second program. However I'm not sure how to do that.

import java.awt.*;

import javax.swing.*;

import java.awt.event.*;
public class OpeningScreen {
    JFrame frame;
    JPanel main;
    JButton ready1;
    JButton ready2;
    JPanel bottom;
    JLabel label;
public OpeningScreen(){
    UIManager.put("Button.background", Color.cyan);
    UIManager.put("Button.foreground", Color.magenta);

    UIManager.put("ToolTip.background", Color.magenta);
    frame=new JFrame("Super Tuesday");
    main=new JPanel();
    ready1=new JButton("CLICK IF READY");
    ready2=new JButton("CLICK IF READY");
    label=new JLabel("SUPER TUESDAY");
    bottom=new JPanel();
    label.setFont(label.getFont().deriveFont(50.0f));
    frame.setSize(480, 800);
    frame.setLayout(new BorderLayout());
    frame.add(main, BorderLayout.CENTER);
    bottom.setLayout(new BorderLayout());
    ready1.setToolTipText("CLICK ME TO START THE GAME");
    ready2.setToolTipText("CLICK ME TO START THE GAME");

    main.setBackground(Color.gray);
    label.setForeground(Color.white);

    ready1.setFont(ready1.getFont().deriveFont(20.0f));
    ready2.setFont(ready2.getFont().deriveFont(20.0f));
    ready1.setForeground(Color.pink);
    ready2.setForeground(Color.pink);
    ready1.setPreferredSize(new Dimension(240,150 ));
    ready2.setPreferredSize(new Dimension(240, 150));
    bottom.setPreferredSize(new Dimension(600, 150));
    main.setLayout(new FlowLayout());
    main.add(label, BorderLayout.NORTH);
    frame.add(bottom, BorderLayout.SOUTH);
    bottom.add(ready1, BorderLayout.WEST);
    bottom.add(ready2, BorderLayout.EAST);
    MyMouseManager1 mmm1=new MyMouseManager1();
    MyMouseManager2 mmm2=new MyMouseManager2();
    ready1.addMouseListener(mmm1);
    ready2.addMouseListener(mmm2);
    frame.setVisible(true);
}
    class MyMouseManager1 implements MouseListener{
        public void mouseClicked(MouseEvent e) {
            ready1.setBackground(Color.green);
            ready1.setForeground(Color.white);
            ready1.setText("READY!");


        }

          public void mousePressed(MouseEvent e) {

          }

          public void mouseReleased(MouseEvent e) {


          }

          public void mouseEntered(MouseEvent e) {

          }

          public void mouseExited(MouseEvent e) {


          }
          public void mouseDragged(MouseEvent e) {

          }
          public void mouseMoved(MouseEvent e) {

    }
    }
    class MyMouseManager2 implements MouseListener{
        public void mouseClicked(MouseEvent e) {
            ready2.setBackground(Color.green);
            ready2.setForeground(Color.white);
            ready2.setText("READY!");
        }

          public void mousePressed(MouseEvent e) {

          }

          public void mouseReleased(MouseEvent e) {


          }

          public void mouseEntered(MouseEvent e) {

          }

          public void mouseExited(MouseEvent e) {


          }
          public void mouseDragged(MouseEvent e) {

          }
          public void mouseMoved(MouseEvent e) {

    }

    }

    public static void main(String[] args){
    OpeningScreen smartie=new OpeningScreen();


    }
}

Here is the second program. Please don't copy. heh.

I want this one to replace the first program. I'm not sure how to even start with this though, since this is my first attempt at any game, or anything beyond a one class program.

Answer 1

No, you really don't want a java.awt.Applet to replace a JFrame, trust me. They're both used in two vastly different situations, and while the Swing library that underlies JFrames is about 4 years out of date, the AWT library that underlies java.awt.Applet is about 20 years out of date. Just stay clear of Applet.

Instead your GUI classes should be geared towards creating JPanels, which can then be placed into JFrames or JDialogs, or JTabbedPanes, or swapped via CardLayouts, wherever needed. This will greatly increase the flexibility of your GUI coding, and in fact this is what I recommend -- that you swap views via a CardLayout.

Also -- don't use MouseListeners for your JButton listeners but instead use ActionListeners. MouseListeners won't respond to space bar presses, won't be disabled if the button becomes disabled, and can be capricious if you base behavior on the mouseClicked method. Use the proper tool for the job: ActionListeners, or even better, Actions.

For example:

import java.awt.BorderLayout;
import java.awt.CardLayout;
import java.awt.Dimension;
import java.awt.Font;
import java.awt.GridBagLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.geom.AffineTransform;

   public MainGui() {
      setLayout(cardLayout);
      add(startUpPanel, startUpPanel.getName());
      add(gamePanel, gamePanel.getName());
   }

      cardLayout.next(this);
