Swing/AWT/SWT :: Implement CSS In Java Via A JEditorPane
Aug 5, 2014
I'm trying to implement CSS in Java via a JEditorPane and an HTMLEditorKit. The CSS is included below. It *should* create a container with one on the left, small, and one on the right, large. It works flawlessly on JSFiddle [URL] ...., but on Java, it won't put the two divs next to each other. Is this a problem in Java/Netbeans or is it my problem? It creates the divs, but beneath each other. The JEditorPane is wide enough for all of them to fit.
Coding:
Java:
private void loadBulletins() {
//<editor-fold defaultstate="collapsed" desc="HTML/CSS Script">
String eBullStyles = "#divMsgs{ "
+ "height: 99px; "
+ "margin: auto; "
+ "background-color: #3399FF; "
[code]....

I am working on a simple online chat program. I have build the server services and generally everything works smoothly.Now for the input area i use a JEditorPane as like the output message area. The reason of choosing JEditorPane is because i want to apply some CSS on future...
Now under the input message area there are two JButtons. One for attachments and other one for emoticons. Now i am trying to make a Popup Menu with all my Emoticons Images when someone click the JButton(emoticons). I was thinking about a JList inside a popupMenu but that kind of thing is mostly impossible i guess. Any way to automaticaly convert String to images for example when someone type in inputJEditor something like this :) or this :( to convert it to emoticon image ...

I have dragged and dropped a jTextArea from netbeans palette onto my form. But when I right clicked for Event > action > actionPerformed for implementation, I realized such was not there, unlike the jTextField component. For example, I have tried this but it didn't work:
//{
Import java.swing.*;
JTextArea txa = new JTextArea();
txa.getText(jTextArea1);
txa.setText(jTextArea1);
txa.setTextWrap(true);
//}

I am trying to make a ChessBoard class composed of an array of JLabels inside a JPanel with a grid layout. I am also trying to override the getPreferredSize method so that the board will change size when I resize the main window (in another class in which I will instancize this class as part of a larger GUI). I got this kind of layout working before, but now I am trying to get it to work with multiple classes. However, after copying in the part of the previous code corresponding to the panel's layout, I am encountering some errors that I don't know how to solve. Specifically, when I try to override the getPreferredSize method, the compiler tells me "method does not override or implement a method from a super type, " and that it can't find the method "getPreferredSize"
Here's my code:
public class ChessBoard extends JPanel//the panel that this class extends is the boardHousing
{
//mental chess board piece array
Piece mentalBoard[][] = new Piece[8][8];
//actual GUI chessboard JLabel Array
static JLabel chessBoard[][] = new JLabel[8][8];
[Code] ....
I would just think that I was overriding the method incorrectly, but the weird thing is that I got that specific section of code to work before -- the only thing different now is that there are multiple classes, so my ChessBoard class itself is extending JPanel.

So I created an interface which has the method
int getCalls();
I am trying to implement this method in another class but I'm not sure how to do so. My attempt is:
public getCalls(){ return getCalls(); }
When I run the program it sends the following exception:
Exception in thread "main" java.lang.StackOverflowError
at FibonacciForget.getCalls(FibonacciForget.java:14)
and it highlights the [return getCalls();] part.
What is the correct way to implement the getCalls() method?

Coding a web application using Java 6. Try to implement the session timeout for users.
In the web.xml, I added:
<session-config>
<session-timeout>480</session-timeout> <!-- jsp will expire in 8 hours -->
</session-config>
Now, during the runtime, if a user does not touch the jsp page for 8 hours (after the user has signed in), the session timeout mechanism will kick in. At that point, the server side will automatically execute:
rd = req.getRequestDispatcher("/signin.jsp");
So that the user will have to re-sign in, before continue the work.
How can I achieve this goal?

I'm trying to build a program that contains the ability to:
(1) insert new node at head,
(2) print out contents of the list in order,
(3) remove first node from head,
(4) remove last node from tail,
(5) find a target value,
(6) give total number of occurrences of a target value, and
(7) give total number of items in list.
The areas I'm struggling with implementing are: (
- remove from tail - I know how to find the final node but I can't quite figure out how to set it to null since its initial type is an integer.
- find a target value - how to make the parameters quite workout so the user can simply input an integer value.
- The solution is probably really simple but I can't figure out how to print out the results of these methods when I call them.
public class Node
{
private int data;
private Node link;
// Node Constructor 1
public Node()
{
data = 0;
link = null;
[code]....

I need to design 'notepad' application as my assignment.
Requirement: Only text is allowed, all the characters are having same size and font. It should have feature like new, open, save , save as , exit , UNDO , find , replace and font.
For this i use JTextArea and menu bar .
I am able to develop features like new, open, save , save as , exit. Need to implement now UNDO , find , replace and font but struck at 'UNDO'.
UNDO feature should be enable only when user writing in the writing area but not when it opens any file. What i thought is to have a flag on whenever user save whatever he wrote and if he use select UNDO then it check for the flag. If flag is ON then it will not do UNDO and if flag is not set then it cleared everything from the Text Area.

I would like to implement a variable in a class that is used in another class, how can I do that?
I have a Mall class and a Customer class I would like to associate the position of the customer that is in the Mall class and also implement the same in the Customer class.
Here is a small part of the code without all the methods.
//the two objects
Mall m = new Mall("RandomMall",50,30);
Customer c1= new Customer("Jack",1240);
//the first part of the mall class without the methods
class Mall{
private String name;
private int width,length;
String[][]grid = new String[width][length];

I want to implement a kind of "container" in which to store objects (instances) of different types. Then with an iterator I'd call common methods. This is what I have in mind:
Java Code:
with(Positionables){
translate(2, 0, 4);
} mh_sh_highlight_all('java');
Where translate(x, y, z) is a method common for objects in Positionables which objects are of different types (Sphere, Box etc.).
Now I was thinking Positionables could be a List<Positionable> and Positionable is an abstract class and Sphere and Box extends from it. But I don't know how to propagate the call of translate() to the subclasses.
What are the best approaches for this matter? It would be perfect if I could make it so I could somehow use the "with" construction like in the example above.

I'm writing a simple queue program using a netbeans as a GUI program I've used netbeans GUI editor to create the GUI my main problem was I've written the queuing code to a button function it works but it runs only once and the queue becomes empty on the second run. So I implemented a class which will create the queue outside the button click event but when I do that I get a Symbol not found: method error . The place where I get the error:
addStd1.setText("Add Student");
addStd1.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
addStd1ActionPerformed(evt);
}
My button function with the class:
class stdQueCls{
Queue stdQue;
public stdQueCls(){
stdQue = new LinkedList();
}
private void addStd1ActionPerformed(java.awt.event.ActionEvent evt) {

I need to implement the attached interface ("Locality"). In the attached UML diagram it has a 1 on 1 relationship with the class "Team". I don't know if this can be somehow implemented in Java. Can I create the attribute "team" in the Locality interface and let it be used by the "Town" and "City" classes? Could it be better to implement it as an abstract class instead?
