Non functional radio buttons and messed up array

[flameofSuzaku]

Hi. I've been working on a homework problem and ran into a bunch of little things that went wrong. The assignment is to make a magic 8Ball and for extra point to add radio buttons to toggle btwn the 8Ball and a Fortune teller.

We're supposed to randomly display the responses which are stored as an array. I can only get it to select one random number. Even if i click the button alot, its the same response. The radio buttons are visible but the event I put for them don't work.

Can someone take a look and tell me what i did wrong? I tried rearranging things to get the radio buttons to work that that didn't help.

Code:

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

public class EightBallWindow extends JFrame {
	
	private JPanel panel1;
	private JPanel panel2;
	private JPanel panel3;
	private JPanel panel4;
	private JRadioButton eightBallradio;
	private JRadioButton fortuneradio;
	private JLabel question;
	private JTextArea textArea;
	private JButton predictButton;
	private JButton fortuneButton;
	private JButton clearButton;
	int rows = 20;
	int cols = 30;
	
	//Constructs the eightball window
	public EightBallWindow()
	{
		setTitle("The Magic 8 Ball");
		
		setSize(800, 500);
		
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		
		//sets layout manager to arrange the panels
		setLayout(new BorderLayout());
		
		build8BallPanel();
		
		addRadioButtons();
		
		//adds panels to specific areas of the screeen
		add(panel1, BorderLayout.NORTH);
		add(panel2, BorderLayout.EAST);
		add(panel3, BorderLayout.WEST);
		add(panel4, BorderLayout.SOUTH);
		
		pack();
		
		setVisible(true);
	}
	
	private class RadioButtonListener implements ActionListener
	{
		public void actionPerformed(ActionEvent radio)
		{
			if(eightBallradio.isSelected())
			{
				//calls method to build the 8Ball screen
				build8BallPanel();
			}
			else if(fortuneradio.isSelected())
			{
				//calls method to build the 8Ball screen
				buildFortunePanel();
			}
		}
	}
	private void addRadioButtons()
	{
		//Creates and Groups the radio buttons
		eightBallradio = new JRadioButton("Magic 8 Ball", true);
		fortuneradio = new JRadioButton("Fortune Teller");
		
		ButtonGroup group = new ButtonGroup();
		
		group.add(eightBallradio);
		group.add(fortuneradio);
		
		//Create action listeners for the radio buttons
		eightBallradio.addActionListener(new RadioButtonListener());
		fortuneradio.addActionListener(new RadioButtonListener());
		
		panel4 = new JPanel();
		
		panel4.add(eightBallradio);
		panel4.add(fortuneradio);	
	}
	
	private void build8BallPanel()
	{
		//Create buttons and their action listeners
		question = new JLabel("Got a question about your future?");
		predictButton = new JButton("Your Future Now!");
		predictButton.addActionListener(new PredictButtonListener());
		
		clearButton = new JButton("Clear");
		clearButton.addActionListener(new ClearButtonListener());
		
		textArea = new JTextArea(rows, cols);
		
		panel1 = new JPanel();
		panel2 = new JPanel();
		panel3 = new JPanel();
		
		//Adds all the different components to the appropriate panel
		panel1.add(question);
		panel2.add(textArea);
		panel3.add(predictButton);
		panel3.add(clearButton);		
	}
	
	private void buildFortunePanel()
	{
		//Create buttons and their action listeners
		question = new JLabel("See the furture");
		fortuneButton = new JButton("Your Future Now!");
		fortuneButton.addActionListener(new FortuneButtonListener());
		
		clearButton = new JButton("Clear");
		clearButton.addActionListener(new ClearButtonListener());
		
		textArea = new JTextArea(rows, cols);
		
		panel1 = new JPanel();
		panel2 = new JPanel();
		panel3 = new JPanel();
		panel4 = new JPanel();
		
		//Adds all the different components to the appropriate panel
		panel1.add(question);
		panel2.add(textArea);
		panel3.add(fortuneButton);
		panel3.add(clearButton);		
	}
	
	private class FortuneButtonListener implements ActionListener
	{
		public void actionPerformed(ActionEvent fortune)
		{
			/*Declare and initiate String array.  String array will hold 
			 * the */
			String[] answers = new String[10];
			answers[0] = "Always try your best" + "\n";
			answers[1] = "Don't count on it" + "\n";
			answers[2] = "In your dreams" + "\n";
			answers[3] = "Answer currently unavailable" + "\n";
			answers[4] = "Outlook is very hopefull" + "\n";
			answers[5] = "Yes" + "\n";
			answers[6] = "No" + "\n";
			answers[7] = "Absolutely" + "\n";
			answers[8] = "That is a definate possibility" + "\n";
			answers[9] = "Don't see it happening" + "\n";
			
			Random randomNumbers = new Random(10);
			int selection = randomNumbers.nextInt(10);
			
			textArea.append(answers[selection]);
		}		
	}
	
	private class PredictButtonListener implements ActionListener
	{
		public void actionPerformed(ActionEvent predict)
		{
			/*Declare and initiate String array.  String array will hold

			String[] answers = new String[10];
			answers[0] = "Definately" + "\n";

			Random randomNumbers = new Random(10);
			int selection = randomNumbers.nextInt(10);
			
			textArea.append(answers[selection]);
		}
	}
	private class ClearButtonListener implements ActionListener
	{
		public void actionPerformed(ActionEvent clear)
		{
			textArea.setText("");
		}
	}
}

here is the main ags

Code:

public class EightBall {
	
	public static void main(String[]args)
	{
		new EightBallWindow();
	}	
}
