I want to be able to get an image online and display on my JPanel but for some reason my image wont load and just shows a blank square, but when I try to load an image from my hard drive it works just fine.
Here is what I was trying to do:
Java Code:
BufferedImage image;
try
{
image = ImageIO.read(SiteMainMenu.class.getResource("insert link here"));
}
catch(Exception e)
{
} mh_sh_highlight_all('java');
I am trying to use images as my backgrounds for my JPanel.the problem is when I run the program the images don't show at first.T hey start to show after I have switched to another panel and then switch back. Here are my codes
//for loading image
static public Image LoadIcon(String file) {
URL icoURL = windows.class.getResource(file);
Image img = Toolkit.getDefaultToolkit().createImage(icoURL);
return img;
[Code] ......
I read many posts online and watched tutorials on YouTube. I can't seem to get this work. Notice I am not using any drawing/graphics capabilities - I'd like to keep it this way as we have not gotten that far yet in my studies.The image is in a source folder titled Images under/in my project.
Java Code:
private JPanel jpImage = new JPanel();
private JLabel lblImage;
private ImageIcon image;
private Image img;
// All those above defined prior to method

I'm working on loading SVG images on Jpanel using "Apache(tm) Batik SVG Toolkit" , but after the image get loaded it has "white background" and "not transparent" one like PNG images.
I checked "fill" of rect attribute on the xml file of the svg image and it was correctly set to none, I also Tested the image on html document and it was trasparent, but in my java app it has white background.
The Question is there any way to load SVG images with transparent background on Jpanel ?
The code below is just the GUI for a slot machine. Currently when play is clicked it displays the random number, I'm trying to make it so each random number displays an image in the GUI instead. For example if the random numbers were 2,2,3 it would display Cherry, Cherry, Bells. I started changing field1 to the image but realised I was on the wrong track as it would just display the same image not one allocated to a number. I've left in what I started doing.
how to do it?

import java.awt.event.*;

So I'm trying to make an applet that displays images of playing cards. The applet should load a deck of 52 playing card images (the folder is called "images"). The applet should shuffle the deck (using a random number generator) and display the first 10 cards of the shuffled deck. I then have to display the cards in two rows of five cards each.
With this code I have about 100 errors and I'm not sure what I'm doing wrong:
import java.util.Random;
import java.awt.Image;
import java.applet.Applet;
import java.awt.Graphics;
public class unit12 extends Applet
{
Image card1, card2, card3, card4, card5, card6, card7, card8, card9, card10;

it is supposed that i placed the image "pippo.gif" in my project "src" folder, isn't it? anyway I tried to add a new folder to my build Path, and place pippo.gif on it, but it doesn't work.
"In this assignment you will use an applet to display images of playing cards. The applet should load a deck of 52 playing card images from the "images" folder that you downloaded. The applet should shuffle the deck (use a random number generator) and display the first 10 cards of the shuffled deck. Display the cards in two rows of five cards each."
That is my goal for this assignment. I've got my code compiling and I will post it below and I've got an html page but when I try to open it I get an error

I'm trying to figure out how to display a JPANEL and be able to select a file to review it, but off the bat I having problmes figuring out the first steps I have some code how to start properly or what i need to make this work,
import java.io.*;

public class checkValue {
//create a Dialog box to locate the site file
public static String propertiesFilePath;
public static JButton siteBrowse = new JButton("Browse");
public static void main(String[] args){

So I'm trying to make an applet that displays images of cards. The applet has a deck of 52 playing card images. It should shuffle the deck with a random number generator and display the first 10 cards of the shuffled deck.
With this code I have about 100 errors and I'm not sure what I'm doing wrong: I know I have to use arrays in order to ultimately display the images, but do I have to create Image objects for the Image [] cards array? I am getting many "class, interface, enum expected" errors as well as others.

i think the problem is to do with my images not being recognised. I put them in my source in User>...>workspace>src which is correct as far as i know. From what i know the images should show up if i look at my src file in eclipse but they dont. I tried changing the file type from .png to .jpg but it makes no difference.

I have a Main() class that extends JPanel and I'm trying to add Card() that also extends JPanel.When I add a Card() or Main() object to the JFrame directly, it works fine. The problem arises when I try to add a Card() object to the Main() object.
I edited the code a little bit to make it easier to read so hopefully it's fine.
Main() code:
public class Main extends JPanel implements Runnable {
// HARDCODED OPTIONS
public static final int WIN_WIDTH = 1200;
public static final int WIN_HEIGHT = 800;
public static final int GRID_X = 9;
public static final int GRID_Y = 5;

I know I have a 64 bit OS, my computer, will simply not download the 64 bit version of java when I hit the big ol' red button on the main page. and yes, I have gone to the downloads page and downloaded the one that's 64 bit, but whenever I try to play games, it simply won't let me go online. I have tried uninstalling and reinstalling, but nothing seems to work.

View Replies View RelatedFor a project I have to create an online survey, I cannot use a per-made online survey system because I have really specific needs that no pre-made system can satisfy, so my idea would be to create it in java and store the data in some simple text file, which are fairly easy to work with in java. My question is, is it possible, and if yes how difficult is it, to put the entire thing online? What worries me isn't putting the applet itself online, but the text files that should collect the data, I already have the website to host it.
