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);
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 reading from a database(SQL Server 2012) and storing that information in a ResultSet. I am then trying to display that information using a DataTable.
Here is my managed bean
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ package clientspage; import java.io.Serializable;
[Code].....
The ID and the commandLinks are being displayed but the Client is not.
I have a empty JList in which I hit a button LOAD DATA which should load all the data. but once I load data i try to fill in the List but I keep getting errors.
String[] aos = new String[itrList.size()]; itrList.toArray(aos); //JList listFAIL = new JList(aos); //list = new JList(itrList.toArray()); //list.removeAll(); list.setListData(aos); JScrollPane s = new JScrollPane(list);
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.
import java.util.*; public class TrafficIncidents { public static void main(String[] args) { Scanner s = new Scanner (System.in); // Array for days String [][] days = {{"Sat"},
[Code] ....
This is my output:
Day AM PM -------------------------------- Sat Sun Mon Tues Wed Thurs Fri 5 1 1 2 4 1 0
Basically I want to align the AM traffic incidents under the heading "AM" but am not sure how to accomplish this. I am using separate arrays for all three of these types of information and need the info to line up with their respective titles.
I am getting blank page only. I created sample JSF project with Facelet in Eclipse. The source code contains basic page with header, content & footer. I refer the site Support-Eclipse . I deployed war into Tomcat. I am unable to find the problem.
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.*; /** * DataAnalyzer Class * This class instantiates the methods from the ReadFiles Class and Calculations Class.
I have html code that use form and the result displayed with display tag library the form forward to servlet page but when I use a javascript to change value of hidden after returning to html page the value of hidden input deos not change
Displaying 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
table records
Here is my code below:
<% //Retrieve the values from the DB while (rs.next()) { category_name1=rs.getString("category_name"); subcategory_name1=rs.getString("subcategory_name");
[code]....
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 explored the track of the OCR . But the result produced is not consistent with the captured picture. How can I do this? I have no other tracks ....
In my servlet page I call one xml response from third party server and make write it in file using filewriter and store it in local,after that
response.setHeader("Refresh", "1; URL=test.jsp");
Using this code i goes to test.jsp page ,in that test.jsp file ,i place iframe tag like <iframe src="file:///D:/sample/result.xml" /> but it does not show the content what can i do?
I have noticed, that if i call setVisible(true) before i add the button, then it works, but the button is not displayed... How can i achieve that the button is displays AND the KeyListener works?
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.
I 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'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();
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?
import java.util.Scanner; import java.io.*; public class hangman{ public static void main (String[] args) throws FileNotFoundException{ Scanner kb = new Scanner(System.in); String guess; String guesses = ""; int wrongGuess = 8;

Sir, I'am new to Swing Programming. I have to create an application where an image is displayed on one Label. The same image has to be split in parts and stored in database pert wise. Later the user has to retrieve the entire image by viewing a small part of the image. I have already displayed the full image on the Label, now i don't know how to split the image and store it part wise in the database.
