I'm following this tutorial![URL] I've copied over a lot of the code and also copied/pasted other parts! I understand how it works, but I can't figure out why the "X" or "O" won't paint onto the screen when the window is clicked on! Only a button is drawn when I click on the screen.

So, I have this simple program that paints a string on JPanel using g2.drawString("Hello world", 40, 120). Basically, I want to be able to keep track of many strings on the JPanel at once. I'm not sure how to do this. For example, I would want to have an ArrayList of objects that keep track of these strings.
I want to be able to click-and-drag these strings so I will need to know there locations, etc.
Right now, using g2.drawString, it only draws the string. I want something like gw.draw(myStringObject).
I have an empty string and I want to add to it crosses and naughts. I want to simulate a board of TicTacToe game. My goal is print out 5 strings like this : "xox xxx oxo". There are 3 groups of symbols separated with a space. The crosses and naughts are filled randomly.
Random rand = new Random(); char[] characters = new char[] { 'x', 'o' }; int numOfTimes = 0; while (numOfTimes < 5) { String board = ""; String space = " "; for (int group = 0; group < 3 ; group++)
Is it possible to paint to the screen without using methods such as paint(), paintBorder(), paintChildren, paintBorder, paintComponent, paintAll() and any other paint like methods I may have missed. These are, by the way, taken both from JComponent and Component. So, is it possible?
Making a memory game where you click a square it turns over an image and you match the two pretty simple. My issue is my images are not displaying and I am not sure why everything looks correct to me.
i am making a game in java eclipse which has a 3 category for kiddie, teenage and young adult, that also has subcategory which Q&A and images, my problem was i cant make an images quiz (like a logo quiz) that is randomize what i only made was to display an only one image if i clicked button and its only one image, how can i make showing one image then another one image if i clicked some button like NEXT...
Java 2D Drawing Application. The application will contain the following elements:
a) an Undo button to undo the last shape drawn.
b) a Clear button to clear all shapes from the drawing.
c) a combo box for selecting the shape to draw, a line, oval, or rectangle.
d) a checkbox which specifies if the shape should be filled or unfilled.
e) a checkbox to specify whether to paint using a gradient.
f) two JButtons that each show a JColorChooser dialog to allow the user to choose the first and second color in the gradient.
g) a text field for entering the Stroke width.
h) a text field for entering the Stroke dash length.
I) a checkbox for specifying whether to draw a dashed or solid line.
j) a JPanel on which the shapes are drawn.
k) a status bar JLabel at the bottom of the frame that displays the current location of the mouse on the draw panel.
If the user selects to draw with a gradient, set the Paint on the shape to be a gradient of the two colors chosen by the user. If the user does not chosen to draw with a gradient, the Paint with a solid color of the 1st Color.
Note: When dragging the mouse to create a new shape, the shape should be drawn as the mouse is dragged.
i would like to create a menu like below where if i clicked on "DRAW", a frame to draw will appear and when i clicked on animate, I can animate an object drawn. I tried on using JButton, but I donno how to customize the design n so I would like to know is there other ways so tat my menu will appear as below?
Is there a reason why this error is occurring? I can't identify what's causing it to happen.
Java Code:
package tictac1; import java.util.*; public class TicTacToe{ //Instance variables private char[][] board; //2D array of chars for the board public TicTacToe(){ //creates a board where each space holds whitespace board = new char[3][3]; for (int row = 0; row < 3; row ++){
I'm trying to create a cursor for a game that moves square by square. While it will move to the next square, though, it leaves the image of the previous cursor on the last square it was on.
As a visual explanation, this is what the program looks like on launch:
This is what it's suppose to look like after you press the right arrow key once (made by forcibly changing launch coordinates):
And this is what it actually looks like after you press the right arrow key once:
Here is the code for the program:

I'm fully aware that I could just use g.clearRect on the area and remove it for sure, but I know for a fact I shouldn't have to as I have another program I made a long time ago that tried to do something similar without needing to resort to that.
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.
I'm creating a game called Mouse Trap and I'm having an issue with a graphic drawn using AWT. Basically, when the mouse collides with the cheese, I want the cheese to disappear, or call (cheese[i].hide()). However, the cheese does not appear. hide() works for all other objects that inherit from PFigure, but the cheese will not. It's created a major issue in my game, and basically the only task left to accomplish.I believe my problem lies within Cheese.java, method draw(). For example, if I replace it with an example drawing, this problem goes away!:
public void draw() { Graphics g = panel.getGraphics(); g.setColor(Color.blue); g.drawOval(x + width / 4 , y + 1, width / 2, height / 2);
[Code] ....
I have three classes below that most likely involve the problem, feel free to ask if you need the others.PFigure.java (This class cannot be changed as a requirement to my project)
import java.awt.*; public abstract class PFigure implements Comparable { protected int x, y; // Current position of the figure protected int width, height; // Drawn (displayed) this size protected int priority; // Can use to determine "winner" protected Panel panel; // Panel the figure lives on
I'm creating a card game and I'm having trouble getting a card gif to display. A card is drawn from an 52 card deck arraylist, and I then need to match that drawn card with the similarly named gif in an arraylist of card gifs, to display the gif on a card GUI. I have put my game, card, deck and graphical class below:
Card - public class Card { public String number; public String suit; public Card(String n, String s) { number = n; suit = s;
[Code] ....
The arrayList of card gifs (which contains all 52 gifs for the cards) is in the graphical class and my arrayList that contains the deck of cards in textual form (that I've imported from a textfile) is in deck. The names of the gifs in the gif arraylist are the same as the card names in my textual card arraylist (for example, 3h.gif is 3h in my card arraylist), so I believe I can use a .equals statement to match the card that has been drawn to the gif.
Here is what the gifs look like in their folder, which is an arraylist in my graphical class :
Here is what the drawn card looks like after the textual card arraylist has been shuffled:
The brown card in that image isn't the displayed card that has been drawn, it's just a graphical deck that I put in, I can't get the card that has been drawn on the GUI to display on the actual card frame, as you can see.
I am thinking of a project for my university the teachers liked it but I am not sure if its even possible.I am trying to make an andriod app. What I want to do is take a picture of a hand drawn logic circuit (having the AND, OR, NOT ... gates) recognize the gates, and make a circuit in the moblie and run it on all possible inputs.
For this I will have to make a simulator on mobile, that I dont think is the hard part. The problem is how could recognize the gates from a picture. Example of logical circuit is attached ( assume its hand drawn )..I found out that theres a edge detection plugin in java but still I dont think its enought to recognize the gates. Please share any algorithm or any technique or tools that I can use to make this thing.
I am making a quiz in Java. I need to be able to add images and colours into my quiz, to make the GUI look more appealing. At the moment, the JOptionPane that I am using looks very plain and boring. I want to be able to have my quiz running the same as it is at the moment, but I want to be able to import the images, add colours, and add Here is a copy of my quiz code:
I am quite new to Java. I have downloaded a tictac example Java applet code and I run it on Eclipse with no problems. But when I try to test it outside Eclipse by doing the following:
I copy the .class file and two gif-images to another location and call the Java from html code:
If I draw (drawLine) the X and O instead of using gif, then it works.... so its really the gif-loading which is the problem.

I am currently drawing graphics onto a JPanel, by overriding the standard paintComponent method.
Is it possible to call a method to draw some predefined shapes, instead of filling this method with all the stuff I need drawn, and if so, how do I do that?
I simply want to paint an image on my frame, just once each time the paint() method is called, but how to call the paint method in any good way. This is how it looks:
I am screwing around with mouse listeners so i decided to make a basic paint program. It works fine but when it draws more than 100 circles it errors out. i know why its doing it (its because i set the array to 100) but my question is how to make it so it has not limit in the array.
Here is the code
public class PaintProject extends Applet { int numClicks = 100; int numCicles; int xCoord[]; int yCoord[]; boolean paint;
