Application For Images Duel
May 20, 2014
I need to make android app for image comparison. It has to show two images and user will choose which image he prefer by using radio button . After clicking one radio button app should save the result of a duel and show another pair of images.
If there is N images it will be ((n*n)-n)/2 duels. I think of something like this - [URL] .... but instead of 2 radio buttons it will be 9 - 4 for each image (depending on preference) and 1 neutral button(no preference).
How to achieve that. I started using java and eclipse recently only so it is all new to me. I made an activity in xml so far and I tried to make class for changing imageview 1 and 2 assuming that all images will be named a1,a2,a3 .
package com.example.ahp;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
[code]....

This is my class with the GUI:
import java.awt.FlowLayout;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.JPasswordField;
[code]....
Eclipse error message:
Exception in thread "main" java.lang.NullPointerException
at javax.swing.ImageIcon.<init>(ImageIcon.java:205)
at GUI.<init>(GUI.java:26)
at Apples.main(Apples.java:7)
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.

1.Created a dynamic web project JWStartProject in eclipse
2.Create a HelloWorld.java class under default package.
import javax.swing.*;
public class HelloWorld extends JFrame {
private static final long serialVersionUID = 4968624166243565348L;
private JLabel label = new JLabel("Hello Java Web START!");
public HelloWorld() {
super("Jave Web Start Example");
this.setSize(350, 200);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE );

I just finished a tutorial on youtube that covers the basic java, and now i want to try and make a game / program thing, only problem is that i have never worked with graphics before (i have tried to make ovals, rectangles, and other things with the paint method tho )
I know how to make a jframe and a jpanel, and i feel like i can make a simple "game" (not a complicated one, just a simple one with a guy walking around on the screen) in fact i have already make a such game, where you are a oval walking around on the screen, so thats not really my problem.
My problem is that i want to draw an image on the screen that can walk around instead of the oval, but how to do that. I have made a new project and set up the jframe and jpanel, and my code looks like this:
(main)
import javax.swing.JFrame;
public class main_class {
public static void main(String[] args){
JFrame f = new JFrame();
f.setTitle("title");
f.setVisible(true);
f.setSize(800,600);
[code]...
but once again, i get a blank jframe with no image and no "test" string . How i can display images on the screen?

I usually code in PHP, C++ and ActionScript.I'm trying to follow an example of how to add images to a full screen application. What he does is that he adds a JPG background image, and then 4 PNG images. I tried to do it like I always do, by writing the code by myself looking at the book. It didn't work. I searched for errors in the code, changed some things, tried different things, but it didn't work. Then I tried to use his own code, that I downloaded from his website. That didn't work either.. I tried to find another way to add an image, and I can't seem to figure out a way to implement images in any other way into this class that's written in this book.. My Java programming level isn't just high enough.
Here's the code for the file where the images load, downloaded from the authors website (I've modified the brackets and some spaces so that it becomes easier to read):
Java Code:
import java.awt.*;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
public class ImageTest extends JFrame {
public static void main(String[] args) {
DisplayMode displayMode;
[code]....

I am currently working on Java software which resize jpeg images and change DPI also. For JPEG images having app0JFIF node it works fine and the images new DPI is reflected in Photoshop. But if app0JFIF node not exist, I am trying to create a new one and set the DPI value there. Everything is going proper but if I open these images in photoshop it does not reflect new DPI but the size changes.
Java Code:
double dpi_in_inch = 0.393701 * newres;
File file1 = new File(imgName);
image = ImageIO.read(file1);
int wd, hi;
wd = (int) (newsize * dpi_in_inch);

I'm just wondering whether it is possible to use images as a button in Java. I have two images that I want to use to create a rollover effect, is this possible? And then I would like to reset my java program when the button is clicked, is this also possible?

I have been trying my hand at making 2d top down view games and have found myself repeatedly using the same code so i created a file with all the functions so when it is down i just import the jar and dont have to keep rewriting functions. I have trouble because the background is loaded on the screen and i dont know why as i didn't tell it to load. In fact I set the panels visiblity to false. Both of my classes are in the same package. Why I still get the Image.

I am still playing around with decks of cards, and am now trying to implement some visualizations using Applets.
Here is how I enter my deck of cards into an array list: this works just fine:
String[] Suits = new String[]{"S","H","D","C"};
String[] Values = new String[]{"A","2","3","4","5","6","7","8","9","10","J","Q","K"};
ArrayList<String> deck = new ArrayList<String>();
for(String suit : Suits) {
for(String value : Values) {
deck.add(suit+"_"+value);
}
}
The end result of this is an array 'deck' which contains a string representing each of the 52 playing cards. Great.
Now I would also like to use some pictures for future implementations I am working on. I have 52 images (.png, though I doubt it matters) stored in the right place. They are named as "H_5.png", and "S_A.png", for example, just as I named the cards in the previous array. I would like to do something as follows
ArrayList<Image> deckpic = new ArrayList<Image>();
for(String suit : Suits) {
for(String value : Values) {
deckpic.add(getImage(suit+"_"+value+".png"));
}
}
Now of course this doesn't work. The line
suit+"_"+value+".png"
is a string, not the name of a file. How I have previously loaded images is to use something like this:
the_pic = getImage("picture_of_pony.jpg");
but of course I can't use the quotations in my card loop, since I want "suit" and "value" to range and not just be the strings suit and value.

Java Code:
private JPanel jpImage = new JPanel();
private JLabel lblImage;
private ImageIcon image;
private Image img;
// All those above defined prior to method

So I am trying to make this java applet that will display a random image of three that is a sub folder of my src folder within my project.
When you run the project currently all you get is a white applet. Here is the code:
import java.applet.Applet;
import java. awt.*;
public class myPictures extends Applet {
Image action;
public void paint(Graphics g){
int rint = (int)(Math.random() * 3);
if(rint == 0){
action = getImage(getDocumentBase(), "../../images/bee3.jpg");
} else if(rint == 1){
action = getImage(getDocumentBase(), "../../images/bee1.jpg");
} else {
action = getImage(getDocumentBase(), "../../images/bee2.jpg");
} } }

To limit the amount of drawing done i want unmoving objects to be painted once. So i set a boolean. When it first load the boolean is false so it draws then after first draw i never want it to draw the objects agian but leave them on the screen. Now in this if you run it you get a black screen.
If you didnt have the "getContentPane().setBackground(Color.black)" it would work fine and show a blue brick. Is there something I don't understand about the setBackgound Function that makes it automatically redone even when not called? and if so how do i overwrite this?

You basically paste a url Into a textarea and choose an Image for the link.The Image link Is then appended to a html file.
I'd like to put everything In a single jar file but I'm not sure what to do so the user can access the html file.
The only two options I can think of are:
a) create the html document on the fly when the jar runs.
b) Is to run a bat command when the jar Is executed that will extract the jar files.
The user can either choose from a number of Images In the logos folder for common websites or add new Images. Since the folder isn't empty , It seems like extracting the jar files Is necessary.

I have a question about the execution of code to draw images relative to code that comes after that. I don't normally do this sort of thinghere's the problematic code:
int stn = 0;
while (stn < 10)
{
glb1.xOfText += 20;
glb1.yOfText += 20;
gc1.drawImage(glb1.img1 , glb1.xOfText , glb1.yOfText);
TimeKeeper.pause(500);
stn++;
}
Where glb1 is a final reference to an object that holds common data for the game.while its x and y values say they are for text, they are also used for image placement (at least during this testing phase.)
gc1 is the "graphics context" of the canvas that the images are being drawn on.
The person who wrote this said, "When the attached code is run, the calls to TimeKeeper.pause(500), which in turn call Thread.sleep(500), are all executed in row, and then the results of drawing the image 10 times is displayed. (I know because some of the previous image pastes left some visual data behind.)"
I recall from reading about drawing graphics (a long time ago) that drawImage() could take time, but I don't know why the thread does not indeed sleep between calls to drawImage().

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.*;
import java.awt.event.*;

how to phrase the question. I created a small applet in java.. it allows me to move a toon around a blank applet window. I am using four gif files that have a walking animation in them. The issue i am having is after moving around the gif just flashes in and out really quickly.. when i start the program, moving up and down seems to be working perfectly fine, but the moment i move left or right it starts messing up for all directions. here is my code.
