Just some sample code:
Java Code:
mainPanel.add(background, new Integer(10));
cards.add(king[0] = new Card(200, 200, TILE_SIZE, TILE_SIZE, 0, 0)); mh_sh_highlight_all('java');
Then, when a card is created, it calls:
Java Code: Main.mainPanel.add(this, new Integer(1)); mh_sh_highlight_all('java');
Yet for some reason, the background is always painted OVER the card UNLESS I set the background to -1.
One of the random number generators in Java extract the higher-order bits of the random number in order to get a longer period.
I'm not sure if I understand how this is done. Suppose that the random number r = 0000 1100 1000 1101. If we extract the 16 most significant bits from r; is the new number r = 0000 1100 or r = 0000 1100 0000 0000?
Any link to the accurate explanation of binary trees in java?

I am writing this program for my Java level 1 class. I am able to get it to compile and run, however nothing is outputted. Below are the instructions and the code that I have written.
Instructions:
Write an application that calculates and displays the amount of money a user would have if his or her money could be invested at 5 percent interest for one year. Create a method that prompts the user for the starting value of the investment and returns it to the calling program. Call a separate method to do the calculation, and return the result to be displayed.
Below is the code that I have written
import java.util.Scanner;
public class Interest
{
//main method
public static void main(String[] args)
{
originalAmount();
Scanner input = new Scanner(System.in);

Trying to get an image to display in a GUI.
try {
ByteArrayInputStream in = new ByteArrayInputStream(
transferWorker.bOutput
.toByteArray());
BufferedImage bufferedImage = ImageIO
.read(in);

But nothing is happening in the GUI. I have stepped through and bufferedimage contains the data, but its not being displayed. Whats happening is, an image is being transmitted to serial port of laptop, so i'm taking it in and storing it in a BufferOutputStream and then trying to open it in my GUI class.

I am trying to get items to display that would display in a command prompt now into a GUI. I am freaking lost at the moment, probably because I've been staring at this code for over a week now. I have included all the files that are necessary to run the program as an attachment for your own testing purposes. Should I be using a TextField to display the data from the CSV files? How do I get the data to be displayed? How would I get it to be displayed based on the different files Staples (newSTPL.csv), Apple (newAPPL.csv), and Microsoft (newMSFT.csv)?

View Replies View RelatedDisplaying the records in a table. I am looking for a group header to be placed above each printed table for its related category and subcategory, as well as, the no. of the records for each table to be shown at the top of the table.
The table contains columns for category, subcategory, name. ex:
Category Subcategory Name
CON Retail AAA
CON Wholesale BBB
SPEC Retail CCC
What I am looking for is the below layout:
Category/Subcategory (No. of records) –similar to a group header
Name – Country ..etc ----Table header

The problem in the above code is that it is showing the group headers category & sub category multiple times and the count is incorrect.
Here I would like to collect automatically in a file ( txt) the characters displayed on the screen. I'm working on a system that the database is remote. To receive information, there is a terminal by which sends commands. The feedback is displayed only on the screen and you can only print. This is actually a terminal black screen, white character, such as command line "DOS" . The software can not export , or access to the database or other means of information retrieval .

I'm new to JSF and I'm facing a problem with displaying German umlauts correctly.
I have built a site that uses an inputText to submit text that will be displayed in a list of paragraphs (as simple html... <li><p>text</p></li> etc.). A managed bean is used as a controller to store data in backend and to retrieve it from backend for display. In backend the data is stored in a list of strings and using annotations this data is written to respectively read from file system on shutdown/startup via serialization. Sometimes when I'm sending German umlauts from my webbrowser they're not displayed correctly, other times however they are which is pretty weird to me.
I've built the project with NetBeans 8 and I made sure that under Properties -> Sources the Encoding is set to UTF-8. In the xhtml page for display the encoding is set as follwed:
<?xml version="1.0" encoding="UTF-8"?> //first line
<meta http-equiv="content-type" content="text/html; charset=utf-8"/> //in the head
<h:form [...] acceptcharset="UTF-8"> //all forms surrounding the inputText and the paragaraph list
I'm developing on a Ubuntu 14.04 desktop. For deployment I transfer the .war file via ssh to my server which is Ubuntu server (currently not sure which version, might be 12) and there I deploy the .war file on my Glassfish server online.
An example of how the input appears when it's incorrectly displayed: ä
The same letter appears like this when it's correctly displayed: ä
Another example, incorrect: ö
correct: ö
Once the data is input its appearance won't change anymore so I assume the incorrect encoding happens already before the data is stored in backend. I'm not sure yet under which conditions the data is displayed incorrectly.
I'm using BarChart and I've a very strange problem. Is not very simple create a test case to understand where is the problem.
In the first image is displayed a bar with the value of 2 but as you can see the y axis is not correct.
In the second image the value displayed is 4 but the y axis is completely busted.
Important thing: In my real app I change data of the chart every time the user change a combobox value (the period).
First image
Second image
This is a test case that simulate what I'm doing in my app with the only difference that data are fetched remotely with an async request in my real app.
Chart.java
public class Chart extends Application implements Initializable {
@FXML
private BarChart<String, Integer> chart;
private ObjectProperty<ObservableList<Series<String, Integer>>> seriesProperty = new SimpleObjectProperty<ObservableList<Series<String, Integer>>>();
[Code] .....
Unfortunately with this simple test case the chart display correctly data.

View Replies View RelatedI have one row editable datatable.I have implemented email validation to one of the column where error message must display on blur of email field.This is working fine.I have a dialog with form to be displayed in the same page. Validation is implemented to this form also with on blur event. The dialog validation message gets displayed on blur but along with that the main form also displays the same validation message. This should not happen.

The message with id lpcErrMsg is the one that i am displaying on blur in the main page when email format is wrong.And this message gets displayed with dialog field validation also although i have never referred to this id to be rendered in the dialog.
The message with id lpcDlgMsg is the message that i am displaying inside the dialog with widgetvar dlg on blur.As of now i have implemented blur event validation for the first required field in the dialog.

I created a simple Hangman game. It functions correctly, the only issue is when the file contains a phrase (2 or more words), spaces are not displayed when the program is run. For example, if the phrase was Java Programming Forums.
It would appear as _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _.
I want there to be spaces in between the words. How could I fix this? What would I need to add to my code?
