How to get these two classes to interact?

[David Triple]

I cant get his to work

import java.util.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class JHiLo2 extends JFrame implements ActionListener
{
	JButton DealButton = new JButton("Deal");
	JButton ShuffleButton = new JButton("Shuffle");
	JLabel totalResult = new JLabel("The more the merrier");
    Font bigFont = new Font("Helvetica", Font.ITALIC+Font.BOLD, 24);
    JLabel PlayCard = new JLabel("Player Card");
    JLabel HouseCard = new JLabel("House Card");
    JLabel PlayerWin = new JLabel("Player Wins");
    JLabel HouseWin = new JLabel("House Wins");
   	JLabel Msg = new JLabel("Msg");
   	JTextField Player = new JTextField("");
   	JTextField House = new JTextField("");
   	JTextField PlayWin = new JTextField("");
   	JTextField HouseWins = new JTextField("");
   	JTextField MsgT = new JTextField("");


	// constructor: typically here is where one-time inializations occur
	public JHiLo2() {
		super( "Party Planner Calculator" ); // call JFrame constructor
	Container con = getContentPane(); //get container handle/context (it alredy exist in JFrame)
		con.setLayout(new GridLayout(6,1));	// Set container layout

		con.add(PlayCard);  con.add(Player);
		con.add(HouseCard); con.add(House);
		con.add(PlayerWin); con.add(PlayWin);
		con.add(HouseWin);  con.add(HouseWins);
		con.add(Msg);       con.add(MsgT);
        con.add(DealButton);
		con.add(ShuffleButton);


        DealButton.addActionListener(this);  //register this component with Event Listener
		ShuffleButton.addActionListener(this);  //register this component with Event Listener
	   // by deafult frame size is 0 and is invisible
		setSize( 375, 220 );  // set window size
		setVisible( true );   // show window

	}

	public static void main(String[] args) throws Exception {
       JHiLo2 application = new JHiLo2();
      application.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
	}


	// Event listener will call this method every time there is an event
	// generated by a component that has registered with the Listener
	public void actionPerformed(ActionEvent e) {
		Object source = e.getSource();


		//define an card object
		PlayDeck MyPlayDeck = new PlayDeck();
		Card PlayerCard;
		Card HouseCard;
		int  PlayerScore = 0,  HouseScore = 0;
		int PlayHand;

		System.out.println("\nShuffling Deck....\n");
		JOptionPane.showMessageDialog(null, "Welcome to the Hi Lo Table \n\nShuffling Deck...");
		MyPlayDeck.shuffle();


		while (true){
			PlayHand = JOptionPane.showConfirmDialog(null, "Do you want to play another hand?");
			if (PlayHand != JButton.Deal)
			   break;  // exit game
			// deal hand
			PlayerCard = MyPlayDeck.dealCard();
			HouseCard = MyPlayDeck.dealCard();


			// display player and house cards
			JOptionPane.showMessageDialog(null, "Player Card: " + PlayerCard +
										"\nHouse Card: " +   HouseCard);
			// show winner, no provision for ACE being best card
			if (PlayerCard.getNumber() > HouseCard.getNumber() ) {
			   JOptionPane.showMessageDialog(null, "Player wins, congratulations!");
			   PlayerScore++;
			}
			else{
			   JOptionPane.showMessageDialog(null, "House wins");
			   HouseScore++;
			}
		} //end of while

		//Show final score...
		JOptionPane.showMessageDialog(null, "Player wins: " + PlayerScore +
											"\nHouse wins: " + HouseScore);
		System.exit(0);  //needed to terminate (graphics) application
	} // end of main
} //end of class HiLo

I forgot to add the explanation. I need the JOptions to show up in the JText fields, the JOptions are only there to show what i need to show up on the Jtext, but i cant get the two classes to ineract with each other. What should i do?

[Wouter Oet]

If read your question multiple times but I'm still not sure what you want. Could you explain it a bit more?

[David Triple]

Basically i need the Jtext field to show everything the Joptionpane is showing. So when the player clicks shuffle i need the jtext field MsgT to say "Shuffling" and then when deal is hit it needs to say "dealt". After the cards are the Jtextfield should show both player and house cards, then udpate the number of hands won by both sides. when i try to compile it it says variable player is not found. It cant get the card game to interact with my container.

[Wouter Oet]

MsgT.setText("The text");

Remember that the Java naming convention for variables is that they should begin with a lowercase letter.

Hi David Triple,
I have few suggestions
1) Both Deal and Shuffle button's are sharing same actionListener . Make them to have separate listeners
2) Keep one stop button to stop the game.

You require Inner class here. And inner class will use outer class variable (JText). To change the text message value.

public class JHiLo2 extends JFrame {
           JText showProgress;

          class Deal implements ActionListener {
                 public void actionPerformed(ActionEvent e) {
             // here you can access JText showProgress variable
                 }
          }
         
          class Shuffle implements ActionListener {
                 public void actionPerformed(ActionEvent e) {
             // here you can access JText showProgress variable
                 }
          }  

JHiLo2 is your outer class and Deal and Shuffle are inner class. Inner class can share outerClass variables.

and this is is inserted in the container or where the actual deal and shuffle calculations are placed? This is my first program combining classes and its a more difficult than i thought.

Ok so here is what im got now, but all my card variables are not working?
I have no idea whats going on

import java.util.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class JHiLo2 extends JFrame{

    JLabel PlayCard = new JLabel("Player Card");
    JLabel HouseCard = new JLabel("House Card");
    JLabel PlayerWin = new JLabel("Player Wins");
    JLabel HouseWin = new JLabel("House Wins");
    JLabel Msg = new JLabel("Msg");
    JTextField Player = new JTextField("");
    JTextField House = new JTextField("");
    JTextField PlayWin = new JTextField("");
    JTextField HouseWins = new JTextField("");
    JTextField MsgT = new JTextField("");


    // constructor: typically here is where one-time inializations occur
    public JHiLo2() {
        super( "Party Planner Calculator" ); // call JFrame constructor
    Container con = getContentPane(); //get container handle/context (it alredy exist in JFrame)
        con.setLayout(new GridLayout(6,1)); // Set container layout

        con.add(PlayCard);  con.add(Player);
        con.add(HouseCard); con.add(House);
        con.add(PlayerWin); con.add(PlayWin);
        con.add(HouseWin);  con.add(HouseWins);
