JSF :: Displaying Value In OutputText When Some Event Occurs
Apr 15, 2014
I have one requirement where when i click on the attribute i would like to create an action and display the same in OutputText.
Ex:
This is Attribute Description outputText :
<rich:columnGroup id="CMAttributeBrowserDescriptionRow2">
<rich:column id="CMAttributeBrowserDescriptionColumn2" styleClass="selectedObj"
rendered="#{CMBrowserBean.attributePresent}" >
<!--<h:outputText id="SelectedObjectDescription1" render="true" value="#{currentAttribute.value}"/>-->
[b][quote]<h:outputText styleClass="attributeTableFont1" readonly="false" id="attributeTextdescription" disabled="false"/>[/quote][/b]
</rich:column>
</rich:columnGroup>
The action should be for :
<rich:column id="AttributeColumn2" styleClass="parentBrowserColumn">
[b]<a onclick="document.getElementById('CMBrowser:0:CMAttributeBrowserDescriptionForm:attributeTextdescription').value=#{currentAttribute.name}" >[/b]<h:outputText id="AttributeName" title="#{currentAttribute.name}" value="#{currentAttribute.name}"
styleClass="attributeValueFont" /></a>
</rich:column>
I am unable to get the text coming on outputText, when i click on the above attribute.

why when i use the following outputText tag
<h:outputText value="Testone"/>
The generated HTML is
<div>Testone</div>
And when i use the next outputText tag the output is enclosed in quotes
<h:outputText value='<a href="http://some.site.com/login?URL=http://a.b.com/">Some sitelink</a>'/>
"<a href="http://some.site.com/login?URL=http://a.b.com/">Some sitelink</a>"
To temporarily fix something i need to generate an html tag using a param value. Here an example
<h:outputText value="<a href="http://some.domain.nl/login?URL={0}">Hi There</a>">
<f:param value="#{request.scheme}://#{request.serverName}:#{request.serverPort}#{request.contextPath}" />
</h:outputText>

I don't understand that the error occurs when I don't initialize the variable myPoint. Whereas, I initialize the variable myPoint after variable declaration and before place of error.
package enumeration;
import java.util.Random;
public class Craps {
[Code]....
When I initialize the variable myPoint to zero in its decleration, the error disappear. But why? I have already initialized the variable myPoint in default case before the line of error occured..

I'm trying to write a program that counts the number of times each number in an array occurs. In theory I understand how it work, you take the first element in the array, compare it again the rest of the array and any time it occurs in the array you increment a counter by 1. Then move onto the next element A[1] and so on...
This is what I've done so far :
public static void main(String[] args) {
int[] array = {5,6,2,5,2,2,0,1,6};
int count = 0;
for(int i = 0; i <array.length; i++) {
int val = array[i];
for(int j = i+1; j<array.length; j++)
[Code] .....
I think I'm on the right track as it correctly prints out the frequency of the first 3 elements, but I'm definitely going wrong somewhere as it just doesn't do it right after that!

When an exception occurs that will affect the entire functioning of a program, in other words, the program will not be able to do what it is intended to do, is it best just print the exception to user and run System.exit(1)? And then force the user to run the program again.

I am currently truing to make this class instantiate 100,000 dice rolls of 2 dice. And I also need to keep track of how many times each possible total occurs and I am having trouble outputting the result. Right now when I run my code it is just showing the results of each of the 100,000 roles.
public class ltefera_DiceRollTest {
public static void main(String[] args) {
ltefera_DiceRoll diceRoll = new ltefera_DiceRoll(10);
System.out.println("Total # of pips" + "
");
diceRoll.printArray();
System.out.println(diceRoll.countDice(2));
System.out.println(diceRoll.isArrayDataValid());
System.out.println(diceRoll.getTotal());
System.out.println(diceRoll.allDifferent());
[code]....
"how many time each possible total occurs"

I'm having issues with JButtons and painting methods, whenever I click a grid on the board, the buttons in the JPanel disappear. Here is the board class:
package GUI;
public class Board extends JPanel implements Observer {
/**
*
*/
// private static final long serialVersionUID = 1L;
private final int boardSizeX;
private final int boardSizeY;
private final int L = 20;
[Code] ....
I know the code is messy in places, this will be fixed later, just need some pointers on how to solve the JButton issue.

Write a recursive Java method countDigitx that takes two integer numbers as input (a number n and digit x) and returns the number of times digits x occurs in number n:
For example if n=23242 and x=2 then the method should return 3 that is the number of times the number 2 found in n.

The game runs fine, however I have to include how many times each letter that is guessed occurs within the word. For example, if the guess is e, the program should print out: The character e occurs in 3 positions. How would I go about doing this??
/*
* A program that plays simple word guessing game. In this game the user provides a list of words to the program.
* The program randomly selects one of the words to be guessed from this list.
* The player then guesses letters in an attempt to figure out what the hidden word might be.
* The number of guesses that the user takes are tracked and reported at the end of the game.

I have built a binary tree, from a file. In each node, I am storing each word as a string, and an int frequency for each time the word occurs. For the assignment, I need to find how many words occur only once in the file. I wrote the program, but for some reason I am getting a number different from what my professor is expecting.
As far as I know, this file has loaded into the tree correctly, because all of my other answers in the assignment are correct. What am I doing wrong?
public void findUnique() {
System.out.println("There are " + findUniqueWords(root, 0) + " unique words.");
}
private int findUniqueWords(Node subTree, int uniqueCount) {
// Base Case: At the end of the branch
if(subTree == null){
return uniqueCount;

How the event Listeners work in java,To get the data based on the event occurs in outside the application. I have this method in one of my API class I am not understanding how this methods are going to work.
public interface SBXPCXMLEventListener {
public void OnReceiveEventXML(String eventXML);
}
private static List<SBXPCXMLEventListener> listenerList = new ArrayList<SBXPCXMLEventListener>();
protected static void fireXMLEvent(String xml) {
[Code] ....
I have done like this.This is used to capture the events from the fingerprint machine when run this class I am not getting any data from the machine when i did thumb impression in the machine.
public class EventListnere implements SBXPCXMLEventListener {
public static void main(String[] args) {
boolean flag = SBXPCProxy.ConnectTcpip(1, "10.0.0.8", 5005, 1234);
System.out.println("flag = " + flag);
// SBXPCProxy.st

java.awt.Component is an abstract class, and it's direct Sub-classes are Button, Canvas, Checkbox, Choice, Container, Label, List, Scrollbar, Text Component
So, when I use addXListener(mylistenerclass m);//which is a method of Component class which object is holding the list of all listeners, for a particular Event Source?
I am under the assumption that - there is an Event Source Object(possibly static) for every Event Source type(mouse, keyboard etc) that holds a list of destinations(classes that implements their listener interface) - added to the the object via addXListener method. When an event happens(mouse click, drag etc) the Event Source Object creates an Event Object and send it to all the destinations. Is my assumption correct? I can't seem to find the location or declaration of Event Source Object and the list where it stores it's registered destinations.

I'm not so new to java i know the basics. I want to make a mastermind game. Just for training purpose.
Now i am at the comparison phase where it is comparing your chosen "colors" with the actual "color code"
This is my code for that part:
guesChars is a char array of 4 of the actual code
readGuess is a string of 4 of which the players has filled in the console
goodGuess is a char at the right position with the right "color"
avgGues is a char with the right "color" at the wrong position
Java Code:
for(int i = 0; i < guessChars.length; i++){
for(int ii = 0; ii < readGuess.length(); ii++){
if(readGuess.charAt(ii) == guessChars[i]){
if(ii == i){
[Code] .....
The problem is when the code is for example
ACDD
and the player guess is
ADDD
Result is
2 right spot right color
1 right color wrong spot
It have to be
2 right spot right color
0 right color wrong spot

How would you begin a program that schedules events? I've found codes that are similar like Calendars, but I need something that will still import the real day, month, year. But I want to have columns that show Room numbers, and rows that shows time slots. How to get started such as which GUI components to use, what packages to import, etc.?

I used java and jsf. I created dynamic datatable in java file. Can i call java method from setOnchange() event?
I am able to call java script function from setOnchange() event. See the below code which is working fine for java script.
HtmlSelectOneMenu selectOneMenu = new HtmlSelectOneMenu();
selectOneMenu.setStyleClass("dropdownStyleTwo");
selectOneMenu.setOnchange("openWin(this);IGNORE_UN LOAD=false");
I wrote openwin() function in java script. But i am not able to call java method change().
Code which is not working.
HtmlSelectOneMenu selectOneMenu = new HtmlSelectOneMenu();
selectOneMenu.setStyleClass("dropdownStyleTwo");
selectOneMenu.setOnchange("myclass.change();IGNORE _UNLOAD=false");
myclass is the bean of class Test. If user select any value from dropdown i want to call change java method. This function will apply the same selected dropdown value to the other record also.

regionsBuilder.setMultiChoiceItems(
displayNames, regionsEnabled,
new DialogInterface.OnMultiChoiceClickListener()
{
@Override
[code]...
Questions:
1. Describe what the code displays. A error message would be shown when the use has selected an insufficient number of options.
2. Describe when an event handler (included in the code) gets executed? The event handler gets executed every time a user selects an option(???)
3. Explain a feature of what is displayed
4. Explain the meaning of all of the parameters in the central, complicated call of the code.
5. Describe how the code handles two possible situations.When the user has selected a sufficient number of options (no less than or equal to 0), then no error message would be shown. On the other hand, an error message will be shown when the user has not selected a sufficient number of options (0). (???)

You're given a number between 0 and 1 that corresponds to the probability of an event occurring.
0.7 is 70%, 0.235 is 23.5%, 0 is 0%, etc.
Someone tries to perform the event, but the event only has the given probability of occurring. Run the probability, and then if it's true, run the event. Otherwise don't run the event.
All I know how to do is generate random numbers (kind of), but if you have 0.2245 I really don't see how generating random numbers can efficiently perform that probability.....
