The serializable class ImagePanel does not declare a static final serialVersionUID field of type long public class ImagePanel extends JPanel{ ^^^^^^^ ^ ^^2 problems (1 error, 1 warning) mh_sh_highlight_all('java');
im basically just trying to put the image inside the GUI and centre the text underneath it. Which is hard to believe since the text is above the image in the code .
I've got a problem with my applet when I run it in a browser (firefox mainly but nothing else is working neither). First of all, the program is "unsigned" according to firefox security system, but I don't think that's where to problem lies. When I start the applet (as an html application) it says:
AccessControlException
Then it says: Access denied ("java.io.FilePermission" "bla, bla, bla (img source on my harddrive)" "read")
How do I get this to work? This is the picture I'm trying to implement: [URL]...
I've tried to add a background image to my calculator , however I have ended up with this ...Calculator.jpg
How do I fix it so the image is behind my buttons etc (as a background) And how do I fix my textarea so it is back to the normal size and not the height of the image? My code is below, please be specific.
import javax.swing.*; import java.awt.*; import java.awt.event.*; /** * Program using SWING components to create a Christmas themed Calculator. */
public class GridBag1 extends JFrame implements ActionListener { private JFrame window= new JFrame("Christmas Calculator");

Sir, I'am new to Swing Programming. I have to create an application where an image is displayed on one Label. The same image has to be split in parts and stored in database pert wise. Later the user has to retrieve the entire image by viewing a small part of the image. I have already displayed the full image on the Label, now i don't know how to split the image and store it part wise in the database.
I stored an image into MySQL database using swings and hibernate but I am struggling to retrieve that image from MySQL database and display same image in the jTable cell and same as on jLabel whatever I retrieve from the database using swings and hibernate .
I'm trying to make a method that takes an image and turns it into a tile image. So if the original image looks like this:
[URL] ....
then the output image should look like this:
[URL] ....
Here's a method that's supposed to do that but for some reason the output image looks the same as the original:
public static int[][] tile(int[][] arr){ int[][] tile = new int[arr.length][arr[0].length]; for (int i = 0; i < arr.length; i++) { tile[i]=arr[i]; } return tile; }
I recently changed the method and the error message I'm getting is "bad operand types for binary operator '+'. Here's the method:
public static int[][] tile(int[][] arr){ int[][] tile = new int[arr.length][arr[0].length]; for (int i = 0; i < arr.length; i++) { for(int j=0; j<arr[i].length;j++){ tile[j]=(tile[j])+(arr[i]); } } return tile; }
I am working on a text based adventure game. (This is NOT OOP at all) The problem comes in at my second if statement inside my loop, it is not adding 1 to my array locations[] it keep printing location[0] then a 1 at the end. Not really sure what is going on here. I would like it to when I type "Go north" it adds 1 to locations[]
E.G locations[0] Go north locations[1] go north locations[2] package com.PenguinGaming; import java.util.Scanner; public class Game{
I'm really struggling adding JLabels to my GUI. The code is giving no errors but the JLables aren't showing up as I think I've done something else wrong. Here's my method for adding the JLabels:
public void showGraphics(){ for(int i=0; i<message.length(); i++){ if(message.charAt(i) == '#'){ JLabel localLabel = new JLabel("test label"); getContentPane().add(localLabel); } } }
I think the problem might be to do with how the rest of the GUI is setup and the fact that I haven't specified where to add the JLabel just that I'm adding them.
I have a supermarket checkout line where i have a list of available products on the left and then a basket on the right with the products in. The products are listed in an array, here is the product class
public class Product { private String name; private double weight; private double price;
[Code] ....
with getters and setters excluded, and the list these are put into
public class productList extends DefaultListModel { public productList (){ super(); } public void addProduct (String name, double weight, double price, int code){ super.addElement(new Product(name, weight, price, code));
i have the price for each product to be displayed in a text field with the following code
addBasketItem = new JButton(); getContentPane().add(addBasketItem); addBasketItem.setText("Add >");
[Code] ....
defaultCheckoutList contains my available items and defaultMainList is the basket, with mainTillPrice being the jtextfield.
This works to get the price however it just replaces each time i make a new entry with the price for the next item, i want a total of the price of all the items i have added, but not sure how.
I want to be able to check that the data for the ID is limited to a certain collection of characters formatted in a certain. For example, I may wish to limit it to 5 lowercase letters or numbers, or a combination of both. How could I do this?
Here is my program. I have to add the outputs from variable 'done' together. It seems to not work inside or outside the loop.
//A program that will find the last/check digit of a Book ISBN number.

I wanted to create a interface with buttons ofshapes and type of transformation where user first select a shape, the shape will appear and user will have to click on the buttons on resize, reflect, rotate or skew to transform to shape.

I am doing a few Spring tutorials and in eclipse and for each tutorial I have to right click my project, build path, and then add external archives and then select the spring JAR files I want to bring in and use before my project will successfully compile and run. I was just wondering is this required for every project or is there a way I can set eclipse up to look in these locations for every project without me having to explicitly tell it too?
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 trying to add two bytes together in binary. The problem is that I need to print the carryover also. The printed result should be 8-bits long if the byte or the integer converted in binary is less than 8-bits the empty space should be filled with 0-s. I figured out how to print and add them, the part with the filling the blank with 0-s too. how to print the carryover. For example:
byte x =15; byte y =9; the output will be :
00011110 - carryover x 00001111 y + 00001001 __________________
00011000 - result
import java.util.Scanner; public class Addbytes { public static void main(String args [])
I am new to swing and I wanted to know how to be able to make a second row of buttons. Right now I have a text pane at the top and at the bottom one row of buttons. But I need to add another row or two of buttons. I've only been coding in Java.
public class TextPane { public static void main(String[] args) throws IOException { ///////////// //I/O FILES// ///////////// //Create the input file FileWriter inputFile = new FileWriter("userInputStory.txt");//story user creates with the <nouns>, <verbs>, etc PrintWriter inputFileWriter = new PrintWriter(inputFile);
So I'm doing a basic MVC layout for a pretty basic game that I am making in order to understand the whole MVC layout. The game requires the user to move up/down/left/right via JButtons on the GUI. Since I'm using an MVC layout and my buttons are in a different class than the ActionListeners, I was wondering what the best way to add the action listeners are?
Method 1:
View Class ActionListener method: Java Code: public void addMovementListeners(ActionListener u, ActionListener d, ActionListener l, ActionListener r){ moveUp.addActionListener(u); moveDown.addActionListener(d); moveLeft.addActionListener(l); moveRight.addActionListener(r);
[Code] ....
Which method is better? Is there another method that is even better than these two? Trying to get this MVC thing down.
