Thread: Help with adding multiple images to an application

load multiple different image files and display them separately

Can you explain your problem? I see that you are using ImageIO class's read method to read files
and are using the Graphics class's drawImage method to draw images.

If you are getting errors you need to tell us. Copy and paste the full text of the error messages here.

Actually I'm not getting any errors, it just plain will not display the second image file. My problem is that i just can't figure out how to make it display that image. Sorry if I was unclear.

One problem I see is that you are not telling the layout manager where to place the JPanels that you are adding to the frame. Your setting of the contentpane and adding to the contentpane seems confused.
Also where do you assign a value to the image2 variable in the ImagePanel class?

Why not create two instances of the class and add them in different places.
Or create one instance of the class and give it the two images so it can draw them.

Ah, thank you very much Norm. I took your advice and added a second argument to the constructor so it is now able to load two different images at once. However, I have a new problem. I started wondering how I could add a very large assortment of images to the program. I'm sure I could just keep adding on to the constructor, but that would get to be very, very cluttered. My thought was that I could just create an array of BufferedImages and use that as the argument for my constructor. I worked on it a little and came up with this code:

import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.*;
import javax.imageio.ImageIO;
import javax.swing.*;
 
public class ImagePanel extends JPanel {
 
    public ImagePanel(BufferedImage images[]) {
        this.image = images[0];
    }
 
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
 
        g.drawImage(image[0], 50, 50, this);
        g.drawImage(image[0], 100, 100, this);
        g.drawImage(image[0], 120, 120, this);
 
    }
 
    public static void main(String[] args) throws IOException {
    		BufferedImage image[] = new BufferedImage[1];
       	image[0] = ImageIO.read(new File("http://www.javaprogrammingforums.com/images/tile1.png"));
       	image[1] = ImageIO.read(new File("http://www.javaprogrammingforums.com/images/tile2.png"));
		ImagePanel contentPane = new ImagePanel(image[]);
 
        JFrame f = new JFrame("dslkh");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setContentPane(contentPane);
        f.setSize(400,400);
        f.setLocation(200,200);
        f.setVisible(true);
    }
}

Unfortunately I get an error when trying to compile it. I get this message:

C:\Users\Drew\Documents\JCreator LE\MyProjects\ImagePanel\src\ImagePanel.java:59: error: '.class' expected
ImagePanel contentPane = new ImagePanel(image[]);

I don't have a clue what that means. Granted I'm pretty new to Java, but I've never seen anything like that before. Do you have any advice for how to fix this?
Also, is there a better way to set this up than the way I am? This was just the simplest way I could think to get multiple images.

You don't use the array referencing notation: ([]) when passing an array. Just use the name of the array.
Leave off the []s

Thank you yet again! I was able to fix up my code and it now does exactly what I want. I can't thank you enough for all of your help. I really appreciate everything that you have done for me.

Glad I could help.
