Swing/AWT/SWT :: Display Images According To Number?
Mar 27, 2014
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.*;
import javax.swing.*;
public class SlotMachineGUI {
JPanel mainPanel;
SlotMachine slotEngine;
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.
import java.util.Random; import java.awt.Image; import java.applet.Applet; import java.awt.Graphics; public class unit12 extends Applet {
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.
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:
"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
import java.applet.Applet; import java.awt.Graphics; import java.awt.Image; import java.util.Random; public class Assignment12 extends Applet { Image card1; Image card2;
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:
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().
I am currently creating a Twitter Application within Java Swing using JSON. I have the JList populating with Home feeds but i also want to get Images displaying next to the Text ...
currently all i am getting is [URL] ....
So a am able to get the URL Link but getting that to a Image seems to be the problem
/ArrayLists final ArrayList<String> TweetArray = new ArrayList<String>(); //Array List for Users Tweets.. final static ArrayList<String> incomingTweets = new ArrayList<String>(); //ArrayList for Incoming Tweets. ArrayList<String> arrayImages = new ArrayList<String>();//ArrayList for incoming Tweet Profile Images private Map<String, ImageIcon> imageMap;
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.
import javax.swing.*; import java.awt.*; import java.awt.event.*; public class CharactorMove extends JApplet implements KeyListener
Is it possible to switch images (on jlabel)on combobox item select. I
If (combobox.selecteditem = value) { SetIcon (resource) // I'm using the default auto generated code used by eclipse when we set an icon for a jlabel in the gui }
i'm currently doing my system now and my problem is about inserting an image to my jframe form with thread because if i insert image and when i run it it blinks too slow comparing if i use simple oval it doesnt blink.
Am trying to dynamically insert buttons (which will be presenting card in a frame) using grid layout.As shown image is getting inserted but its not fit in button.I tried Darryl's Stretch icon as well but of no support.
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 ?

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.
Write a program that will display all the odd number between 1 and 15. here is the code that i use :
Scanner scan = new Scanner (System.in); int i, num=0, count_odd = 0; for(i=1; i<=15; i++) { System.out.println("please enter number "); num = scan.nextInt();
tfrreee i want to display given series in ascending order in java prog here is an error : E:Javajdkin>java ascend 505671Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 7 at ascend.main(ascend.java:9)
Java Code:
class ascend { public static void main (String args[]) { int s[]={ 50,71,81,21,7}; int i; for(i=0;i<=s.length;i++)
I'm trying to output a ten digit phone number as a string on one file, and write another program to write it as a long because I don't know what value I need to use in order to get the code to run properly on either one.
I've chosen to build a GUI that will initially display a window with 'x' number of buttons for different subject areas of physics (kinematics, waves, sound, circuits...etc). I would like to use an Actionlistener for each button so that when its pressed, the JFrame will extend a sidepanel or expand the JFrame with a new JPanel that contains variable Jtextfields so the user can enter data to calculate.
I'd like to know if its possible to do this with the JFrame or should I just open a new window altogether? I have some other features I plan to add to the program, but this is where I am right now.
how difficult is it to add a banner image and imageIcon? By banner image I mean create a Jpanel that will contain a header for the window and will have some cool physics jpg image.
I am working with a program I wrote for class. I got it to compile and do what I want, But I was wondering how I can format my methods to to display a decimal with 1-2 decimal places. Would I create a method in my NumberAnalysis class to do it for me? Or would I declare an instance of the DecimalFormat class in my main method?
import java.util.Scanner; //Needed for Scanner Class import java.io.*; //Need for File and IOException import java.text.DecimalFormat; public class Ex8_11 { public static void main(String[] args) throws IOException{ { DecimalFormat decformatter = new DecimalFormat("#0.00");
[Code] .....
This is my output:
Lowest Number: 1.09 Highest Number: 82.76 Total Number: 367.89000000000004 Total Average Number: 30.657500000000002
Think I just solved the answer to my own question, I did it by declaring double variables in my main method and called the methods and instantiated the variables into the methods... Is there a better way to do this?
package lesson4.skowronek; import java.util.Scanner; //Needed for Scanner Class import java.io.*; //Need for File and IOException import java.text.DecimalFormat; public class Ex8_11 { public static void main(String[] args) throws IOException{
I have returned with yet another problem but I think this one might be a bit easier to fix.
So the whole MO of this program is to take user input, and display the sum of the digits of the number they entered. I am supposed to do this by utilizing methods. So far this is what I have and when I compile it tells me that it "cannot find symbol", which I don't understand as I define what "m" is in the for loop. The other error is that it says:
"Exercise6_2.java:22: error: incompatible types: possible lossy conversion from long to int return result; ^
I don't understand why it's giving me this error nor do I understand why result seems to inherently be an int. (Also the public static int sumDigits(long n) method was given to me by the book so that is what I am supposed to use).
import java.util.Scanner; public class Exercise6_2 { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Enter a integer"); long n = input.nextLong();
