I am trying to generate a random image everytime someone clicks spin. I am not able to generate a random picture. Some help would be really nice. Thanks in advance. Here's my code so far :
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Random;
import javax.swing.*;
public class Gui {
private JFrame frmCarlAlphoncesLab;
private JLabel _lblNewLabel_1;
private JLabel _lblNewLabel_2;
private JLabel _lblNewLabel;
private JButton btnSpin;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Gui window = new Gui();
window.frmCarlAlphoncesLab.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the application.
*/
public Gui() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
frmCarlAlphoncesLab = new JFrame();
frmCarlAlphoncesLab.setTitle("Carl Alphonce\u2019s Lab 8");
frmCarlAlphoncesLab.setBounds(100, 100, 450, 300);
frmCarlAlphoncesLab.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frmCarlAlphoncesLab.getContentPane().setLayout(null);
btnSpin = new JButton("SPIN");
btnSpin.setBounds(159, 124, 89, 23);
frmCarlAlphoncesLab.getContentPane().add(btnSpin);
_lblNewLabel_1 = new JLabel("");
Image img1 = new ImageIcon(this.getClass().getResource("/Purple.png")).getImage();
_lblNewLabel_1.setIcon(new ImageIcon(img1));
_lblNewLabel_1.setBounds(184, 48, 40, 40);
frmCarlAlphoncesLab.getContentPane().add(_lblNewLabel_1);
_lblNewLabel_2 = new JLabel("");
Image img2 = new ImageIcon(this.getClass().getResource("/Green.png")).getImage();
_lblNewLabel_2.setIcon(new ImageIcon(img2));
_lblNewLabel_2.setBounds(83, 48, 40, 40);
frmCarlAlphoncesLab.getContentPane().add(_lblNewLabel_2);
_lblNewLabel = new JLabel("");
Image img = new ImageIcon(this.getClass().getResource("/Red.png")).getImage();
_lblNewLabel.setIcon(new ImageIcon(img));
_lblNewLabel.setBounds(285, 48, 40, 40);
frmCarlAlphoncesLab.getContentPane().add(_lblNewLabel);
EventHandler event = new EventHandler();
btnSpin.addActionListener(event);
}
public class EventHandler implements ActionListener {
private String[] Images = { "Green.png", "Purple.png", "Red" };
Random rand = new Random();
public EventHandler(){
}
@Override
public void actionPerformed(ActionEvent e) {
if(e.getSource()==btnSpin){
Integer a = (int) (Math.random() * 3);
Image myImg = Toolkit.getDefaultToolkit().getImage(Images[a]);
System.out.println("HERE");
}
}
}
}
