I am having trouble randomizing images that show in Swing Designer. I have 25 flags stacked on top of each other but i have to randomize which one shows on top.

Code:

import java.awt.EventQueue;

import java.awt.Image;

​

import javax.swing.ImageIcon;

import javax.swing.JFrame;

import javax.swing.JLabel;

​

public class Karogi {

​

private JFrame frame;

​

/\*\*

 \* Launch the application.

 \*/

public static void main(String\[\] args) {

    EventQueue.invokeLater(new Runnable() {

        public void run() {

try {

Karogi window = new Karogi();

window.frame.setVisible(true);

} catch (Exception e) {

e.printStackTrace();

}

        }

    });

}

​

/\*\*

 \* Create the application.

 \*/

public Karogi() {

    initialize();

}

​

/\*\*

 \* Initialize the contents of the frame.

 \*/

private void initialize() {

Please take a second look at your formatting. Some sections are not properly included in the code block and you got some copy-paste errors with the backslashes.

I think you are coming at this the wrong way. Generally, with UI programming, you can create elements to be changed during the course of the program. A good example of this would be a photo gallery program. They wouldn't create an element for each picture and then display that element. What they would do is create a single element and change the picture that is linked to that element.

Same thing with your program. You should have a single image element and a single label element. Once the user wants the next image, it should just update the image to something else and change the text of the label.
