Creating A Level Editor GUI
Nov 17, 2014
I am working on a game engine with java. I have come to the final stages of the development of this engine now and need a small hand. For this i am using java's built in libary for graphics. and am strugling to create a nice looking GUi with it, What i need:
The class extends the canvas class and adds it to the jframe, i have set the window up as standard and added a menubar, and net the canvas, what I want to do.
For those of you that have used application such as tiled (shown here [URL] .....) what i am wanting to do is create a gui around the canvas similar to this where the parts on the right are resizable up and down and in and out. i was wondering how i would go about incorporating this.

I'm using "standard-kepler-SR2-win32-x86_64" and have installed "jdk-8u5-windows-x64".
But eventhough I can't override a methode like that "@override", it still says me:"annotations are only available, if source lever is 1.5 or greater".
Fine, therefore I installad "jdk-8u5-windows-x64", its the higest one on that oracle side, what else is needed?

I have come across some code where it attempts to save an entity to a database, but before it does it validates that the name of the entity is unique. If it is not unique it throws a runtime exception. This results in the ugly default exception web page being displayed. Is there any way to propagate this back to the JSF page where the user enters and clicks the form button to save the entity? The page already handles some error cases such as "field required" using the h:inputText's 'required' attribute. Need something more for name validation.

binlibresourceshexicon.cmdinside the folder dist.
In this case I could run the .cmd file which has java -cp .;lib;resources client.Test .
c: rycpdist>java hexicon.cmdBut if i put the .cmd file inside bin as like this and run as
c: rycpdistin>java hexicon.cmdI am getting this error Error: Could not find or load main class
Is there any possibility to set the class path in this case

I know that below code would put a lock on current instance of DemoClass, What I am not sure of is the role of lock on Object Class in second example. How does below works - Is it putting a lock on Object Class? If yes how will putting a lock on Object? I mean, locking DemoClass ensure no two threads access it concurrently, how does this apply to Object class?
private final Object lock = new Object();
synchronized (lock)
public class DemoClass
{
public void demoMethod(){
synchronized (this)

We are working with LinkedBinarySearchTrees. One of specs on my assignment is to "Using a level-order traversal, create a 2-D display of your trees, using the forward and back slashes as the branch lines. The tree nodes should be spaced proportionally to show the structure of the tree neatly."

From the tutorial:instance variables can be declared in class level before or after use.But the code below does not compile. Why?
Java Code:
public class MainApp {
i=5;
public static void main(String[] args) {
System.out.println("Hello World");
}
int i;
} mh_sh_highlight_all('java');

I need to do a simulation on the assembly code level by writing a mini-compiler for each ISA, i.e., 4, 3, 2-Address Architecture, Accumulator Architecture, Stack Architecture, and Load-Store Architecture.The input to the simulator is a segment of C program:The basic sample segments of C code are:
1. A = (B + C) * D - E;
2. F = (G + H) - (I + J);
3. G = H + A[I];
4. If (I == J) F = G + H;
Else F = G - H;
5. Loop: G = G + A[I];
I = I + J;
If (I != H) Goto Loop;
6. If (G < H) Goto Less;
7. While (save[I] == K)
I = I + J;

As web server has multiple threads to serve client requests in Thread Pool & to ensure Thread Safety we should not use any variables or Objects at Instance/Class level.But in case of Session Variable which one is the Best Practice as the Session object is used by all the requests to have the same Session ID.
My Code :
public class MyServlet extends HttpServlet {
private static Logger log = Logger.getLogger(ClientRegistrationServlet.class);
private HttpSession session; /* This is used at Instance Level*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

Here is the original code I found on StackOverFlow. It highlights some specific words in a JTextPane.
import javax.swing.*;
import java.awt.*;
import javax.swing.text.*;
public class ColorChangeWhileTyping extends JFrame{
private int findLastNonWordChar (String text, int index) {
while (--index >= 0) {
if (String.valueOf(text.charAt(index)).matches("W")) {
[code]....
I dont know for some reason it doesnt work correctly. The colour goes away after I press Space to write the next word.

I've tried a few different editors, like CKEditor and TinyMCE, but I seem to run into the same problem with every one. The text area seems to be disabled in a modalPanel. Everything looks like it displays properly, but the blinking cursor doesn't show up and you can't enter any text. Below is an example of the a4j:form that I use in the modalPanel with TinyMCE. why I wouldn't be able to enter any text into the editor? Is there a different editor that will work better?
<a4j:form id="commentpanelform">
<htm:table border="0" id="woverify" width="500px">
<htm:tr><htm:td height="20px" valign="top" colspan="2">
<rich:messages styleClass="errorMessage" style="text-align:center;"/>
</htm:td></htm:tr>

I am starting a project of a little game for my brother and I wanted to know whether a few things were possible using Java (I know the basics and am currently learning more, but I have about a year to complete this so I have time to learn what is needed).What I need to be able to do:Be able to view a PDF as well as zoom in and pan around itBe able to enter/edit text in said PDF fileBe able to hide some of the text in this PDFBe able to do this on several PDFs in one program (They won't be open at the same time)
Is it possible to do this in Java? If so, how? (As in, what things would I need to learn or what would I need to complete it)If it makes my question easier, what it will be is a London Underground Tube Map (Which is a PDF file)where some station names disappear and the player has to guess which station(s) are missing.

I'm having a problem with a small text editor I'm trying to create. I have implemented a panel of labels, containing line numbers, on the left of a scrollable text area. The panel is designed to size such that it fits the larger numbers whenever they appear. It does that very well, actually, until either one of the scrollbars appear. As soon as one does appear, it immediately shrinks in width. The horizontal scrollbar even blocks the view a little, making it impossible to see what you are writing on the very last line.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Main implements KeyListener {
public static JPanel tab = new JPanel(false);
public static JTextArea text = new JTextArea();
public static JScrollPane scroll, reflex;
public static JPanel lines;
[code]...
Explanation of the code: There is a main panel which embodies a text area and another container filled with labels of line numbers.Both the text area and line number panel have scroll panels attached. They are synchronized, in order to scroll at the same time.
The main class contains a static function "position" which generates a GridBagConstraints, created for the convenience of single-line creation of constraints.It also implements the KeyListener interface, and waits for change in the amount of lines inside the text area. Afterwards, it changes the panel of labels accordingly.

I am trying to set the font of the editor as the same for the renderer of JTable. I am just a bit confused on how to do this. I don't want any code but maybe a walkthrough on what to do. Here is my abstract table model ....

private ArrayList <Product> prodList = new ArrayList <Product> ();
private String [] columnNames = {"ID", "Description", "Inventory", "Cost", "Order Quantity"};
public ProductTableModel (ArrayList <Product> productList) {
this.prodList = productList;

I want to create a jsp where there is a textbox and the user can change font styles (such as bold, italicized, underline, change color, change font style, highlight align a word/s) inside the textbox just like an MS Word. I'm not looking for a system similar to code ranch's posting of message which displays the tag in a textbox...

I'm using [URL] ....., I'm quite surprise of the fact that there isn't a property for the text value. So you can't bind this component to the model.
Why in our opinion there isn't a property to bind (as in other components)?

I'm trying to program a tile-based map editor and most of it is going quite smoothly except trying to organize the layout. Originally I was going to use 2 frames, one for the map, and 1 for the tile set, but after reading about frames I learned that that is bad practice and is also inconvenient because there is no way to have both frames in focus at once (so you need to click an extra time to gain focus when switching windows). So what I'd like to do is create a single frame application that holds 3 panels. One for the map, one for the tile set, and one for tile settings. This is basically what it would look like:
Note that the tile settings panel uses GUI elements (a border, a JLabel (which starts out empty), a JComboBox, and a JTextField) while the other 2 panels are just drawing panels*
Now I have tried multiple things which either did not work visually (panels were inside panels) or did not compile. One thing I tried was using BoxLayout to put the 2 tile panels vertically within a temporary panel which I then tried to add into the frame after the map panel (with FlowLayout), but that made it look like this: I honestly don't know what else I did that I should write here because in retrospect many of the tings I tried were silly or I don't remember exactly what I did. What would be the best layout to doing what I want?

How do I escape the characters of a primefaces editor?
I have this in form in a xhtml page
<p:editor value="#{managebeanX.valor}" />
but when I try to save this value through a sparql query it says:
virtuoso.jdbc4.VirtuosoException: SQ074: Line 2: SP030: SPARQL compiler, line 2: syntax error at 'Apple' before '-'
Here is the sparql query
INSERT INTO GRAPH <http://localhost:8890/Asst> {
<http://www.dominio.edu#Q1> rdf:type asst:Question; asst:prompt "adada <span class="Apple-tab-span" style="white-space:pre"></span>"^^xsd:string. }
The Blue text is the value of the p:editor. It' has html characters... So I think I need to scape those characters... but how?

What I'm trying to do is make an inventory type program that includes a jtable. In the Jtable in the last column there will be 2 buttons and a textfield to register the value of additions or subtractions to the overal stock amount. (See screenshot in attachment).
As of now I am able to increment or decrement the numbers when the buttons are clicked on however the problem is that if I add 2 to the first row, and then go to add 2 to the next row or any other row for that matter, the value of the previous row is added to the next row, and the previous row reverts back to a value of 0. So basically its like there is only one editor that keeps track of one value no matter what row you are editing.
I need getting it so that I can add different values to each different row depending on the stock being used or received. The following is my code:
Main class
JScrollPane scrollPane = new JScrollPane();
scrollPane.setBounds(10, 155, 643, 233);
IMG.add(scrollPane);
center = new centerJustify();
ts = new tableCellRenderer();
tm = new DefaultTableModel(){

The program below compiles and functions correctly for the most part. It is supposed to be a simple GUI Text Editor with Edit and Format functions. The content pane is supposed to be a scroll pane, however no matter how much I type into the editor, the scroll bar does not appear. Also, the none of the functions under the "Edit" menu work.
Java Code:
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.io.*;
import java.util.*;
import java.util.StringTokenizer;
import java.util.regex.Pattern;
/**
* A simple text editor. It creates and displays the GUI Text Editor.

public class TextEditor extends JFrame implements ActionListener
