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 didn't work a lot with Reflection and now I'm having troubles by writing a method to set a field value of an unknown type.
I wrote a little example program to show, where I cannot find a solution. I explain the problem in the following points:
- there is a class with 4 fields, which 2 are of type primitive int and 2 are Integer
- at line 27 is set the name of the field I want to modify
- if is set field1 or field2 (of type int) there is no problem. In this case the 'case "int"' of the following switch is executed
- if is set field3 or field4 (of type Integer) is executed the 'default' case of the following switch and at line 56 is thrown the cast exception that "Cannot cast java.lang.String to java.lang.Integer"
import java.lang.reflect.Field;
public class TestClass {
public int field1 = 1;
public int field2 = 2;
public Integer field3 = new Integer(3);
public Integer field4 = new Integer("4");

How to create text fields, labels and input boxes on a GUI, we haven't covered these in class as of yet, but I want my project to stand out so I'd like to know how to build a GUI now.

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?
View Replies View RelatedI am trying to run a simple program in which on clicking on the TextField will show some required text under the Text Field .Here is my code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class Awt
{
public static void main(String...s)

I am expecting the on clicking anywhere inside the text field should show me the Text : "Mouse Clicked" . But i am getting this error:
Awt.java:77: error: cannot find symbol
tf.f.setText("Mouse Clicked");}

symbol: variable f
location: variable tf of type Awt

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);
[code]...
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.

View Replies View RelatedI 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);

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
[Code]....
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 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

code used to create watermark in text-field of any registration page?
View Replies View RelatedIn 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).
Trying a simple form with a text field and a submit button; the text field should start with zero and increment by 1 every time a user clicks it.

String param = request.getParameter("integer");
try {
int i = Integer.parseInt(param);

I am generating textfields dynamically using JSTL forEach. Here is the code ..
<c:forEach var="underlyingTickers" items="${underlyingTickersList}" >
<tr>
<td ><input name="underlyingTickers" type="text" id = "underlyingTickers" value="<c:out value='${underlyingTickers}' />">
</td>
</tr>
</c:forEach>
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.
I just started Java a few days ago and I'm having trouble with ActionListener..
Here are my codes so far , i'm having trouble with the
btnDetermineAction10686696_842067395825457_2521361553839739125_n.jpg:

public class NumberAnalyzer extends JFrame{
private JButton btnDetermine, btnClear;
private JTextField txtNumber, txtFactors, txtPrime;
private JLabel lblNumber, lblFactors, lblPrime;
private JPanel pnlNumber, pnlNumber1,
[Code] ....

Identify its factors, write it at FACTORS text field.
Determine if it is prime. If prime, output at PRIME text field is “Yes”, “No” otherwise.
Is it possible to validate the input of a TextField that ist bound to a Property before both values are updated? Following is an example of my problem .....
In my model, there is a SimpleDoubleProperty discount. As you can see, there is some validation logic in the method setDiscount that might be used by other parts of the model.
public class Model {
private DoubleProperty discount = new SimpleDoubleProperty();
public DoubleProperty DiscountProperty() {
return discount;
[Code] ....
My Main class has a Textfield that is bound to the discount-property, a button to put the current value of the discount-property to console and a button to call the setDiscount-method ......
public class Main extends Application {
@Override
public void start(Stage primaryStage) {
try {
Model model = new Model();
BorderPane root = new BorderPane();
Scene scene = new Scene(root,100,100);
[Code] .....
By using the bidirectional Binding between the TextField and the discount-Property, the setter in the model is never called and therefore there is no validation of the input value. When calling the setter programatically with the second button, everything works as expected.
I experimented with neglecting the Binding and using ChangeListeners for both the TextField and the discount-Property but only produced infinte loops when both listeners triggered each other alternating.
I created a jsf page inside my ADF project. Inside I have a button and a text field. If i press button my servlet is activated. It returns a jasper report in pdf format. Now I would like to display my text field value as a jasper report parameter. So this is a part I don't know how to do. How do I get a value of my text field inside servlet? After this I know how to pass it to report.
