Code in java in which if i want to list particular row in matrix it should be displayed using for loop.
For example in 3 X 3 matrix:
1 2 3
1 1 1
1 0 1
If i want to see only 1st row i.e. 1 2 3 then how to do i do this ?
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'am new to java, this question may have been asked earlier but I'm not getting the exact answer.I want to add data from database into at and display it through jsp. But empty or null values is shown i.e no data is being displayed and when I execute the same sql query which is used in code in sql server then required output is displayed. My java code is:
Java Code:
public List < Alarm_Bean > get_Count(String system_Name)
{
if (system_Name.equals("MPS"))
{
try {
con = getConnection();
stmt = con.createStatement();

View Replies View RelatedI've been stuck for the last couple hours trying to understand why the "printInReverse" method is getting into an infinite loop. I was supposed to make a double linked list that you can insert numbers and it orders both ascending and descending; in this case, descending is the "printInReverse" method, which takes the already ordered lists and prints it reversed, like if it was descending, and that's where the problem lives. Here follows the whole code:
import java.util.Scanner;
public class MyList {
private Scanner userInput;
private Integer selectedOption;
private MyListElement firstElement = null;
private boolean exitRequested = false;
[Code] .....
This is supposed to be a method that adds stars after each item in the list.
Java Code:
import java.util.ArrayList;
public class ClientProgram {
public static void main(String[] args) {
ArrayList<String> list = new ArrayList<String>();
list.add("the");
[Code] ...
I'm guessing it's because list.size() changes, though but it should only find that value in the beginning, so it shouldn't be a problem?
I am trying to invoke some methods in a for loop in order to print some info stored in a List. But for some reason, compiler pops a message saying "cannot find symbol - method getEmpID(). You are using a symbol here (a name for a variable, method or class) that has not been declared in any visible scope." But I am pretty sure that method getEmpID (as also getName(), getAfm(), and payment() ) have been declared as public.
Note: My List contains objects of different type (SalariedEmployee, HourlyEmployee). I hope this is not the factor causing this problem.
Java Code:
import java.util.*;
abstract class Employee{
private String name = "";
private String afm = "";
private long EmpID;
static long count=0;

I am making a game in java and for the game board i want to fill the screen with blocks. to do this i stored objects of a class that displays squares into an array list and displayed the array list. however, when i do this all of the squares are drawn on top of anther at the final squares coordinates and i dont know why.
here is the code
// code for adding the squares into the array
nt x = 0;
int y = 0;
int size = 10;
static ArrayList<Map> map = new ArrayList<Map>();
//static ArrayList<Items> items = new ArrayList<Items>();

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);

The List does fill as i have a checker for that.
Trying to get an image to display in a GUI.
try {
ByteArrayInputStream in = new ByteArrayInputStream(
transferWorker.bOutput
.toByteArray());
BufferedImage bufferedImage = ImageIO
.read(in);
[Code] ....
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)?
Java Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

setBounds(0, 0, 200, 200);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
rdButton =new JRadioButton("Login",new ImageIcon(ClassLoader.getSystemResource("Login.png")),true);
add(rdButton);
setVisible(true);

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.

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

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 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.
