I have a super class and an inherited class. What it is supposed to do is display random images in one applet. The images dont match the words and images dont match the wording. What am I doing wrong? Probably a few errors.
Super Class:
import java.awt.Color;;
public class Dukes {
private Color noseColor = Color.red; // default Dukes have red noses
private String action = "../../images/duke/dukeWave.gif"; //default Dukes are friendly
private String whatDoing = "Give me something to do";
private String message= "";
public Dukes() {
int rint = (int)(Math.random() * 3); // randomly generates a 0, 1, or 2
if (rint == 0)
[Code] .....

What I'm trying to do is display an entire deck of cards in 4 hands, randomly shuffled. These will be displayed as images in a pane. The images are numbered 1-52(not using Jokers) so what I have done is created an array that contains those numbers. Then I am randomly shuffling that array. What I can't figure out how to do is display the images using the randomly shuffled numbers in the array to do it? Is this even possible or am I totally on the wrong track on how to do this? This seemed like the obvious way to go when I started. Showing images isn't a problem, it's showing them using the array's element to get the image name that I'm having trouble figuring out.

This is my class with the GUI:
import java.awt.FlowLayout;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.JPasswordField;
[code]....
Eclipse error message:
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.

The program runs well , it adds the applet but it dosn't update the interface unless I press "_"(Minimize) . To be more clear , the object paints a spring wich goes through 4 stages , it is added to the JFrame but it dosn't uptade until I minimize the frame , that is when it goes to the next stage .
The main class which calls the spring to be added to the frame :
public class principal implements ActionListener ,Runnable{
JTextField field;
JFrame frame;
private class Action implements ActionListener {
public void actionPerformed(ActionEvent event) {
frame.repaint();

I created a dialog file:
Java Code:
package com.example.classorganizer;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
[code]...
When I long click item in the list nothing happens. I get no errors at all and I believe that either I put the code in the wrong place or I missed something else that stops Dialog from starting.

Why do I get an error on the hasNext line when I try to compile this?
public static void main(String args[]) throws Exception
{
BufferedReader infile = new BufferedReader(new FileReader( "woodchuck.txt" ));
HashMap<String, Integer> histoMap = new HashMap<String,Integer>();
String word;
while((infile.hasNext()) !=null) {
if(histoMap.get(word)==null)
histoMap.put(word,1);
else
histoMap.put(word, histoMap.get(word)+1);
}
infile.close();
System.out.print(histoMap);

my validAccounts array will not fill properly and has a null value in it.I added a print statement that prints the contents of the array and it is filling correctly but the very last value is null. I am supposed to be asking the user for a account number and password and it is not printing out correctly due to the fact that the array is not filled correctly.
import java.util.*;

I have 4 Primefaces bar charts which sometimes renders, sometimes not. In one of them, I inject a http user session attribute and use it to render the chart (the idea is to show only the data that corresponds to the (logged in) user department).
There are 4 session beans which I'm using the javax.enterprise.context.RequestScoped. Sometimes, the Glassfish destroys the instance as expected, but sometimes not.Based on Exception below, how can I resolve it?
The xhtml below shows the main code for only 2 of the 4 bar charts:
<p:tab title="Horas de Treinamento (por Funci)" closable="true" >
<p:barChart id="horasBars" value="#{chartHorasFunci.modelHoras}"
legendPosition="ne"
orientation="horizontal"
seriesColors="AA5555, 00438F"
xaxisLabel="Horas" yaxisLabel="Funcis"
title="34 Horas de Treinamento (Orçado/Realizado) por Funci"
[Code] .....
The Exception:
SEVERE: Error Rendering View[/capacitacao/capacitacao/index.xhtml]

I am trying to create a tree that is like a take on 21 Questions. The tree pretty much just starts with three default values: the root/first question "Is it a mammal?", a left child "is it: human?", and a right child "is it: fish?", and then it builds off from there. It goes left for YES and right for NO. If the program guesses the wrong animal the user must enter the correct answer and a question that will distinguish the correct answer and the failed answer. That new question then becomes both the the failed answer and new answers's parent.
A little visual:
....................Is it a mammal?
...........It is: human?........Is it: fish?
*lets say it is a mammal but not human, ie a dog
Updated tree:
.....................Is it a mammal?
.....Does it have a tail?............Is it: fish?
Is it: dog?......Is it: human?
My problem is that after I update the tree 3rd time the values do not change properly. Lets say it is a mammal and its does have a tail, BUT its a cat, then, the updated question, which would now go before "is it: dog?" would be something like: "does it chase rodents?", which its left child would be cat and right would be dog.
However, when my program displays the values it would go something like this:
//first run: GOOD
Think of an animal and I will guess it!
Is it a mammal? Enter yes or no:
yes
Is it: human?
no
[Code] .....
So pretty much I can't understand what I'm doing wrong since the values in the print statements are right, but they are wrong during the actual run. Where is my error?

import java.awt.event.KeyListener;
import java.awt.event.MouseEvent;

The parameter for the starting y is "fy" (Half of the screen). When I use the keys "z" and "x" it translates one pixel at a time left and right. That is good, but when I use the keys "a" and "s" it will double each time (good), but the starting y will drop significantly (bad). I tried manipulating the "x" and "fy" variables, but to no avail.

I was trying to do a short program that scans a text for a given word and then tells you how many times that word was repeated in the text. The result was this:
var text = prompt("Write the text to be searched through");
var word = prompt("Write the word to be looked for. Beware of capitals!");
var hits = [];
for (var i = 0; i < text.length; i++) {
if (text[i] === word[0]) {
[Code] ....
However, this doesn't scan the text properly. I think the problem lies in one of the lines from 4 to 8, but, even after thinking quite a lot, I couldn't understand what was it. I thought that by saying that the letter of the text in position [i + k] shuold be equal to the letter of the word in position [k] I could make it work, but it doesn't.

I am trying to only allow the user to input numbers. But I need to enter a number twice before it moves to the next line statement and also skips a line when i enter th number a second time.
How can I go around fixing this.
My code for this is
case 1:
do{
Event event = new Event();
out.println("Please Enter the name.");
event.setEvent(input.next());
input.nextLine();

Have have just started working with JavaFX and SceneBuilder having been a long time Swing developer.
My first foray into the world of JavaFX involves building a rather simple desktop application to parse text based log files with regular expressions.
Currently I am working on the main window for this application. I built a scene in SceneBuilder using a BorderPane for my root.
I placed a TitledPane which contains a TableView in the center section of the BorderPane and a VBox which contains several Buttons in the right section of the BorderPane. When I view the layout in SceneBuilder using the Preview menu item to show the preview in a Window, SceneBuilder shows the scene laid out exactly as it is in the work are and as I would like it laid out.
When I close SceneBuilder and go back to my IDE (Eclipse) and build and run the application the scene is displayed in a window differently than in SceneBuilder preview. When the application executes the scene is laid out as if there has been something placed in the top section of the BorderPane, the TitledPane containing the TableView is centered in the window and the VBox containing the buttons are not aligned with the top of the TitledPane containing the TableView because it is as if there is a "null control" in the top section of the BorderPane.
Why is there a difference in the way SceneBuilder displays the scene and the way the executed application displays the scene?
Also, I recently made some changes to the layout of the controls in SceneBuilder (e.g. changed some padding and location of some controls in their containers and again the scene looks perfect in SceneBuilder but when I execute the application now some components in the container where I made the changes are truncated when the scene is displayed when the application executes.
It is almost as if SceneBuilder is interpreting the FXML one way and the JavaFX API during run time is interpreting the FXML another way.

I'm having problems with using the h:inputFile tag with JSF 2.2 and Glassfish 4.0 on Eclipse. The file uploads work when the enctype is set to "multipart/form-data" in the h:form tag, but AJAX will not work. When I leave out the encType (defaults to "application/x-www-form-urlencoded") AJAX works but the uploads do not work, and in fact Glassfish crashes and generates the message:
The request content-type is not a multipart/form-data
Likewise I'm having the same problems with the PrimeFaces file upload tag p:fileUpload. In a JSF 2.0 it works correctly, but with JSF 2.2 it's giving the same problems and generates the message above.
When I start up Eclipse it tells me that Mojarra 2.2.0 is installed. Is this the source of the problem, and if so, how do I install a later version of Mojarra?

I've written a small program that does factorial by recursion.
I think it works properly for small input like 10, but it stops working properly
if the input becomes large, like 100.
If I try any large input, I get a zero.
Why I am getting 0s.

First and second numbers in another each line represent edges. Third one is wage of each edge.

I was told to create a class named Billing that includes three overloaded computeBill methods for a photobook store.
The first method takes the price of the book ordered, adds 8% tax and returns the total due.
The second method takes the price of the book, and the quantity, adds tax and returns the total.
The final method takes the price, quantity and a coupon discount, adds tax and returns the total.
All of this I have managed fairly well, although I keep getting a strange error at the end of my program that the constructor is undefined. The problem bits of code(the one throwing the errors) are under the comment //Enter values into each of the methods
Code:
package org.CIS406.lab2;
public class Billing {
//Declarations
double bookPrice;
int quantityOrdered;
double couponValue;
[Code] ....
My first thought was to create a constructor for each of the methods that I am using...

I am working on a program that should take an input file as a command line argument and check if that file contains a valid sudoku solution. Right now the main error I am getting is my scanner isn't functioning properly and is throwing inputMismatchexceptions, but Im also not sure about the validity of my functions, and i cannot test them because my scanner isn't working.
import java.util.Scanner;
//This class will read in a possible sudoku solution and test it for validity. If it is invalid, return at least one reason why.
public class SudokuVerifier {
//this function checks a row to see if it contains the numbers 1-9
public static boolean checkRow(int sudoku[][], int i) {
boolean contains=false; // keeps track if the line contains a certain number
for(int k=1; k<=9; k++) { //goes through every number from 1 to 9
for(int j=1; j<sudoku[i].length; j++) { //checks every element in the row to see if it is equal to k
