Thread: How to put in a "new" image in ImageIcon JFrame ?

Hi there. If you are putting pictures in labels inside of a JFrame and there are 3 labels in the JFrame. You want the same picture for the first and second labels, but for the third label you want to change to a new picture.
How would you make it display the new picture ?

ie: I have done this :

ImageIcon icon = new ImageIcon ("devil.gif")

and entered this above label3 in the code to try to display angels.gif

ImageIcon icon = new ImageIcon ("angels.gif")

but I get the error:

LabelDemoGo.java:27: error: variable icon is already defined in method main (String[])

Heres the full code which works fine displaying all three labels with the same picture (But I want to make the third label have a different pictuere)

//LabelDemoGo.java
//Demonstrates the use of image icons in labels.
 
 
import java.awt.*;
import javax.swing.*;
 
public class LabelDemoGo   {
 
//creates and displays the primary application frame.
 
public static void main (String[] args)   {
 
JFrame frame = new JFrame ("Label Demo");
frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
 
ImageIcon icon = new ImageIcon ("devil.gif");
 
JLabel label1, label2, label3;
 
label1 = new JLabel ("TRY ", icon, SwingConstants.CENTER);
 
label2 = new JLabel ("alittle ", icon, SwingConstants.CENTER);
label2.setHorizontalTextPosition (SwingConstants.RIGHT);
label2.setVerticalTextPosition (SwingConstants.CENTER);
 
label3 = new JLabel ("HARDER -", icon, SwingConstants.CENTER);
label3.setHorizontalTextPosition (SwingConstants.RIGHT);
label3.setVerticalTextPosition (SwingConstants.CENTER);
 
JPanel panel = new JPanel();
panel.setBackground (Color.pink);
panel.setPreferredSize (new Dimension (250, 400));
panel.add (label1);
panel.add (label2);
panel.add (label3);
 
frame.getContentPane().add(panel);
frame.pack();
frame.setVisible(true);
 
  }
}

thank you.

Whilst making the following amendments:

ImageIcon icon = new ImageIcon ("devil.gif");
 
JLabel label1, label2;
 
label1 = new JLabel ("TRY ", icon, SwingConstants.CENTER);
 
label2 = new JLabel ("alittle ", icon, SwingConstants.CENTER);
label2.setHorizontalTextPosition (SwingConstants.RIGHT);
label2.setVerticalTextPosition (SwingConstants.CENTER);
 
ImageIcon icon2 = new ImageIcon ("angels.gif");
 
JLabel label3;
label3 = new JLabel ("HARDER -", icon, SwingConstants.CENTER);
label3.setHorizontalTextPosition (SwingConstants.RIGHT);
label3.setVerticalTextPosition (SwingConstants.CENTER);

It compiles and runs but still with the devil.gif where angels.gif should be.....
Line 7 is the code i inserted and I moved - label3; - down to below that.

Maybe ImageIcon class isn't the way to achieve this ?
