If there are 4 values in underlyingTickersList A, B C, D and E ... I am getting those values correctly displayed in each text field.
However if I submit the form with all these value how can I get it in the bean? I guess I need to have dynamic id or name for each text field. How can generate it?
Note** I dont have Struts framework.. I am using request.getParameter to fetch the values and set into the bean variable.
The program contains username and password which on submission checks with the database if the details entered are right or wrong....on right details it Displays Welcome (name) and (lastname) parameters from database.
I'm supposed to write a GUI application letting the user enter a file on the text field and display its hex representation in a text area and vice versa.
Here's my code:
/* * 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 hexconvertor; import java.util.*; import java.io.*; public class HexConvertor extends javax.swing.JFrame {
I have a textField in which I have text in. The text is enter customer name. I would like for this text to disappear whenever the user clicks on the textField to enter a customer name. I am using the automated swing gui builder in NetBeans. Is their some sort of feature for this under properties of the text field? If not then what are my other options?
I need to generate the word document dynamically using java code, included the necessary jar files, No compliation issue, but During run time am getting this error: Could not initialize class org.openxmlformats.schemas.wordprocessingml.x2006. main.CTDocume .using all these jar files: POI-3.6.jar, POI_3.9.jar, Poi-ooxml-3.5,Poi-ooxml-3.6,Poi-ooxml-3.7,Poi-ooxml-3.9,Poi-ooxml-schemas-3.6,Poi-ooxml-schemas-3.9.jar. using the XWPFdocument class. when my cursor get into that line XWPFDocument doc = new XWPFDocument(); getting the above error.
On jsp page i have created table with dynamically added rows now i want to insert the data from dynamic row field into database. How would I get the ids of those dynamically created rows to insert into database using hibernate.
I have a PDF file and I have a text file that contains this data. It has the name of a PDF field along with a database table column name.
Text file: pdfFieldEmployee=Employee; pdfFieldStartDate=StartDate; pdfFieldSalary=Salary; pdfFieldExempt=Exempt
I also have this hash map that contains the database table column names along with their corresponding values:
Employee, Don Parker StartDate, 5/6/2000 Salary, $55000 Exempt, N
How would I read through the text file and the hash map and at the same time do this:
if the pdf field is equal to pdfFieldEmployee, then set pdfFieldEmployee equal to Don Parker. if the pdf field is equal to pdfFieldStartDate, then set pdfFieldStartDate equal to 5/6/2000.
and so on and so on. I would prefer to do this with a loop because I think it would take less code than writing a bunch of if statements.
I have a requirement where in the content of the text area is dynamically populated from the database. I am able to successfully retrieve and display the data on the text area.
However when the content is too large, I am not able to dynamically set the height of the text area. When I try to display the same as a label, the display is flawless, dynamically sets the height as per the content. So, I tried to create a label, with same content and dynamically bind the height to the preferred height as below, but it doesn't work.
// Generate User Note Description TextArea textArea = new TextArea(); Label text = new Label();
// SETTING THE TEXT TO A LABEL TO RETRIEVE THE HEIGHT text.setText(usrNotes.getNote().trim());
i need to develop a java program in which it will ask the user "Username" and "Password" and by which it will login to a wesite.
I have developed a GUI in which the username should be entered in the User "JTextfield" and Password in Password "JPasswordField". I need to make sure that password should not be displayed in the GUI. but I didnt find a way to parse the string (char) entered in the "JPasswordField" to the website.
It is always passing a 'null' character! I tried to search in internet and i found that it wont be able to pass the passwordfield characters but you will be able to check in the main function itself by comparing with another char array in the main program itself whether the password entered is correct or not.
Is there any alternate way for this?
Objective : Parse the password (which is not displayed in the GUI) to a website or some other function where it will use it

I have a question about JTextArea colors. When i set the color to blue and then write something on the JTextArea (JTextArea.append) and then set it back to black everything will be black. How can i solve that? Like in Notepad++ or Eclipse when you write keywords in a JTextArea (where you write your code) only some words change color.
This is my code:
// All the imports public class whatever extends JFrame { JTextArea a = new JTextArea(); public whatever() { super("Title"); add(a);
I'm trying to figure out a good way to allow my users to have some formatting options within a text box in my application. Ultimately, they need to be able to have text that is alternating between two separate fonts, and ideally could have both italicized and bolded words as well.
Coding to show pop when focused on any button or text field...i want to show inf pop when we take mouse cursor on any button or field..want coding to be written in action performed in netbeans....
I want to display a new panel with a text field and a label in it, and add the text from that textfield to an array list each time i press enter. here is what i am trying to do:
public JPanel startStateNoPanel(){ startStateNoPanel = new JPanel(null); startStateNoPanel.setBackground(Color.YELLOW); stateNo = new JLabel(); stateNo.setText("Enter Start State Number: "); stateNo.setBounds(5,40,200,20);
[Code]...
Here is my method to add Panel to Action Panel which is further added to the Frame
public void addPanel(JPanel panel, String name){ ActionPanel.add(panel, name); // there is the card layout on action panel }
symbolCountPanel is a panel which consists of a text field to take numberOf alphabets
if((symbolCountPanel.isShowing()) && (ex.getSource() == symbolCountF)){ if(!isTextFieldEmpty(symbolCountF)){ new SwingWorker<Void, Void>() { protected Void doInBackground() throws Exception { AlphabetCountF.setText(symbolCountF.getText()); setNumberOfAlphabets(Integer.parseInt(symbolCountF.getText())); // setting Number of Alphabets
So basically I have this alpha.dat file which stores data submitted when I execute the alpha class and here I have a AWT textfield which reads a password from user. I have another class called beta and I have another AWT textfield in it which also reads the same password from user. How do I compare both passwords?(I know I need both classes to refer to alpha.dat but how do I compare both textfields in different classes)
I just want to add a text field and a label next to it that says "Hourly Wage".
Also, when I run this in Xcode, it reports back with "Shell Script Invocation Error" "Command usr/bin/java failed with exit code 1".
Here's my program:
package summerIncome; import java.util.Scanner; public class SummerIncomeCalculator { public static void main(String[] args) { jFrame frame = new Jframe("Summer Income Calculator"); frame.setSize(400,300);
I want to use this class and method with all of my buttons and text fields. My program contains 1 push button that adds questions and answers to a test, 2nd button that starts a test, a 3rd button that scores the test, and a text field that enters the user information. How would this work? I know how to create questions and answers, start a test, and score a test it's just a matter of how to implement the button and text fields. I'll post the code that I have done so far.
See:
private class ButtonListener implements ActionListener{ public void actionPerformed (ActionEvent event)
with all of my buttons and text fields.
import javax.swing.JFrame; public class TestingDriver { //----------------------------------------------------------------- // Creates and displays the main program frame. //----------------------------------------------------------------- public static void main (String[] args) { JFrame frame = new JFrame ("Testing Program"); frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
In my application, some text should be added to a text area in response to a click on a button. So as an action listener to this class, I made another class which implements the ActionListener.
Inside this class, I have obtained the text which I want to be added to the text area. But the text area is in another class and for the action listener I wrote another class.
Now the problem is that when I try to add the text to the text area by the following line of code, it says that textArea_1 can not be resolved or is not a field.
Java Code:
ParentPanel.textArea_1.setText("Name:"+ncrarray[0]+" Code:"+ncrarray[1]+" Rank:"+ncrarray[2]); mh_sh_highlight_all('java'); What should I do about it?
Even if I try to write a method like the following in the class in which the text area is created, it gives the same error.
Java Code:
public void printTextArea(String text) { textArea_1.setText(text); } mh_sh_highlight_all('java');
The text area is present inside a constructor of the class. I am writing the method outside the constructor (ofcourse).
