how to display results in a PLAIN_MESSAGE. My program is converting hex to decimal and displaying the results. Here's the code:
package pkgfinal;
import javax.swing.JOptionPane;
import java.util.Scanner;
public class Final {
public static int Convert(String userInput, int base){
int running_sum = 0;

I develop a little app in javaee6 and jsf2. I have a search page which has a search form with 2 fields and a search button when i click search button the results should be displayed in searchresults page.
Here is my code,
search.xhtml page
<h:form id="searchform">
<h:inputText id="deptId" value="#{searchBean.departmentId}"></h:inputText>
<h:inputText id="deptName" value="#{searchBean.deparmentName}"></h:inputText>
<h:commandButton value="Click to Search" action="#{searchBean.searchEmployees}">
[code]...
Issue: searchresults page is is not displaying records though it fetched records from table I'm able to achieve this using search bean as session scope but i want to use the scope as Requestscope.
I have a page that I want to debug, but its hard.
The codes is like this:
public void processPage() {
MessageUtil.addErrorMessage("Error Message");
downloadPDF();
return null;
}
private void downloadPDF() {
[code]...
THE question is why the Message not appear when downloadPDF() was called?
I have created a jsp file which does the simple task of reading data from a mysql database and displaying the results on a web page. Please see below:
<%@ page import="java.io.*,java.util.*,java.sql.*"%>
<%@ page import="javax.servlet.http.*,javax.servlet.*" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>
[Code] ....
However, each time I run the jsp file in the browser with my localhost as server, I get an HTTP Status 500 error.
I'm doing a program where a user enters in exam results for students. Once he's entered the code, the code should split the results in stars in 4 categories.
I am working with a while loop that prints out infinite results. What I want to do is, if the user enters 2 digits, say "12", it should output 1 "*".
If the user enters "21" and "22", it should output "**".
There are 4 categories of marks which are marked with ints range1, range2, range3 and range4, which are user enter digits. Part 1 of the code is to split the user entered digits into its correct ranges. the ranges are 0-29, 30-39, 40-69 and 70-100. I've done the part where when the user enters a digit, it goes into the correct variable. After that when the user enters a digit over 100, the enter results should show up as stars. For example
Enter number =
21
22
44
66
44
23
11
111 (the 111 is where the program breaks and moves on)
So it should then display
0-29 ****
30-39
40-69 ***
70-100
Whatever I'm trying, it displays an infinite amount of stars. If I try to use break, It only outputs a single star, no matter how many digits I enter
Here is the code
int mark = 0;
int range1 = 0, range2 = 0, range3 = 0, range4 = 0;
int count1 = 0, count2 = 0, count3 = 0, count4 = 0;
while (mark >=0 && mark <=100) {

How is it possible to put a gif in swing that automatically changes the frame rate by itself? g.drawImage("file.gif") won't work.
View Replies View RelatedThat's my third day working in Java using Swing and the IntelliJ Idea IDE.I'm trying to do something as simple as displaying a PNG in a window, and I'm doing this:
public class AboutRapide {
public JPanel mainPanel;
private void createUIComponents() {
mainPanel = new ImagePanel();
[cod]....
the problem is that, in the paintComponent method, the Image is never found when I run my app from the IDE, but it is when I run it from Finder in my Mac. Same application. I think it relates to how the application is launched so I guess what's a proper way to refer to a resource file with an image so it can be displayed no matter how the application is launched?Also if I generate a Jar for the application, as the resource gets into the Jar compressed file, it can't also be loaded.
I have an fps counter in my game loop:
public void run()
{
long currentTime,timeDiff;
prevTime = System.nanoTime();
accumulator = 0;
boolean TRUE = true;
[code]...
When I print the fps variable to the terminal window, it show a value of ~59.9998 - very close to the frameRate of 60. That is to be expected, and works well. The problem is that when I deliberately make the game go really slow, by spamming a bunch of enemies, the game looks slow, but the FPS is still apparently ~59.9998. I thought that maybe the paint() method was not calling when it was supposed to, but that might not be the case.
This FPS counter should be working, I can't see where I have gone wrong. Is there a problem with the code, or is there another problem that might cause the screen to be redrawn 10 times a second with an FPS of 60?
I'm currently following this Java tutorial:[URL]
I'm at the Image part of this chapter and I wrote/copied these 2 classes:
[URL]
The error:
Exception in thread "main" java.lang.NullPointerException
at javax.swing.ImageIcon.<init>(Unknown Source)
at image.Board.<init>(Board.java:17)
at image.Image.<init>(Image.java:10)
at image.Image.main(Image.java:20)
I'm fairly certain the problem is the path in this piece of code:
ImageIcon ii = new ImageIcon(this.getClass().getResource("C:GebruikersKristofferworkspaceImagessrcimageNature.jpeg"));
I've done some research and found that I should place the image in the same folder as my .java files, which I did [URL] but the problem still persists.
I have been reading some java guides here [URL] .... and was trying to put a bit of what I have learnt into practice but am having some difficulty. Basically, using netbeans IDE I have created a new jFrameform so that I can place swing components in design mode. What I want to create isnt overly complicated but I just cant seem to get it. In design I have simply added a panel and a button. When I press the button I want to display an image I have located at:
/resources/images/numbers/1.png.
This is my code so far (most of it has been automatically generated from me adding things via design mode:

I assume I need something like below somewhere , do i need to create a draw method? if so how do I call it as it is expecting graphics2d as a parameter, what would I pass into it?

my web browser isn't displaying any web page. When I create the method editorPane.setPage(), it takes forever (about 20 seconds) to show nothing. It'll load the web browser after the 20 seconds of waiting. Here is my code:

/**

private static final long serialVersionUID = 4589041456161585394L;
public Browser() {
super("Browser", true, true);

this.setSize(Desktop.getSingletonInstance().getWidth(), Desktop.getSingletonInstance().getHeight());

I set out to make a Tic-tac-toe (Cross and Noughts) game to test my learning so far. While things have gone pretty well so far, I am absolutely stumped by my current issue. When I compile and run the code, the Grid of buttons that I generate do not appear. However, if I mouse over the window, they seem to then get refreshed/repainted. I cannot for the life of me figure out why this is happening. From Googling the issue, it seems this is either an issue with the layout manager or related to a thread conflict with the GUI? [URL] ....
I'm listing out the code for the game class and the button class.

I need to print certain information from an arraylist depending on the arguments the method has. I'm trying to print the last 3 methods from the database class but nothing is printing and I don't know what the problem is.

/* Comments required
PersonFileReader pfr = new PersonFileReader("person.dat");

On the driver class I just print what the methods from the database class do.

I wrote this small program to take an octal number from the user and convert it to decimal form.

Some conversions work. For example, 77 will be correctly converted to 63, and 77777777 will be converted to 16777215. However, some conversions do not work. An example of this is 775002 gets converted to 74898.
I'm working on a simple site for my friend, and he asked me to link to his other site. I need to have the link to a specific search. For example, if I search for "Heathrow," I need to be able to link a button on the other site so that it can be clicked and directed to the search results on this page. Problem is that this is apparently all Java (which I know nothing of) and how to just copy a link to the results page.

I am having the hardest time trying to figure out how to display an array in a 1-window GUI.
I can display 1 book separately, by basically ignoring the array and creating a new object for each book, but I need all 5 books to display in one window, and that's where I'm lost. I'd really like to use the arrayI built to generate the books in the GUI. The information of each book appearing horizontally, and the different books appearing vertically.
