Im trying to create a program which acts like a fruit machine at the moment i am writing an action listener to work with the spin JButton. i have a number of IconImages constructed. could i possibly set these images as an array and then use the random int method to show a random image? if so how do i go about that?

Ive made an attempt at this and this is what ive come up with (bold text is the relevant text)

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
[B]import java.util.*;[/B] //import random

class fm1 extends JPanel implements ActionListener
{
	public fm1()
	{
		this.setLayout(new GridLayout(3,0));
		Dimension D1 = new Dimension (300, 300);
		Dimension D2 = new Dimension (100, 400);

		ImageIcon java = new ImageIcon("java.jpg");
		ImageIcon orange = new ImageIcon("orange.jpg");
		ImageIcon banana = new ImageIcon("banana.jpg");
		ImageIcon cherry = new ImageIcon("cherry.jpg");
		ImageIcon pear = new ImageIcon("pear.jpg");
		ImageIcon seven = new ImageIcon("seven.jpg");
                                //constructing array
		[B]int[] images = new int[6];
		images[0] = java;
		images[1] = cherry;
		images[2] = orange;
		images[3] = pear;
		images[4] = banana;
		images[5] = seven;[/B]

		JLabel fruit1 = new JLabel(java);
		fruit1.setPreferredSize(D1);		
		fruit1.setOpaque(true);
		this.add(fruit1);

		JLabel fruit2 = new JLabel(java);
 		fruit2.setPreferredSize(D1);		
		fruit2.setOpaque(true);
		this.add(fruit2);

		JLabel fruit3 = new JLabel(java);
		fruit3.setPreferredSize(D1);		
		fruit3.setOpaque(true);
		this.add(fruit3);

		JLabel credit = new JLabel("100");
		credit.setPreferredSize(D2);
		credit.setOpaque(true);
		this.add(credit);

		JLabel outcome = new JLabel("");
		outcome.setPreferredSize(D2);
		outcome.setOpaque(true);
		this.add(outcome);

		JButton spin = new JButton("SPIN");
		spin.addActionListener(this);
		this.add(fruit1);
		
		JButton quit = new JButton("QUIT");
		quit.addActionListener(this);
		this.add(fruit1);
	}

	[B]public void actionPerformed(ActionEvent e)
	{
		// When the button is pressed, change the label to a random image
		Random ran = new Random();
		fruit1 = ran.nextInt(6);
		fruit2 = ran.nextInt(6);
		fruit3 = ran.nextInt(6);
		
	} // end of actionPerformed method[/B]
}

when i compile this i get the following errors

9 errors

i think errors 7, 8 and 9 are because fruit1, 2 and 3 are called within a different set of curly brakets, however i dont know what is wrong with the first 6. can someone help me solve these errors?

The first 6 errors are because you are trying to store icons of type ImageIcon in an int array. You need an ImageIcon array.

The other 3 errors are because fruit1, fruit2 and fruit3 are local variables that exist only while the fm1 constructor is active. Since you want to continue to use them after the fm1 object is instantiated, they should be member variables of fm1. Declare them inside the fm1 class definition, but not within any method definition.

pls help me how to randomize 52 cards?the randomize will get only 8 cards in display it on a 8 jlabels..
