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 RepliesI'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:

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:

Just a quick question about the formatting of text files when using Java. I created a text file called Discount Fly that keeps track of things like a person's name, address, etc. Here is roughly what it looked like in the .txt file:
Name Address Postal Code
Jane Doe Anywhere St, 123 1A2 B3C
However, when I run this code:
static String firstOutput = "";
public static void main(String[] args) throws IOException {
BufferedReader fileRead = new BufferedReader(new FileReader("C:UsersOwnerDocumentsDiscountFly.txt"));
String fileLine = "";
for (int i = 0; i < 12; i++) {
fileLine = fileRead.readLine();
if (fileLine == null) {
break;
[Code] ....
It prints out into JOptionPane as:
NameAddressPostalCode
JaneDoe Anywhere St, 123 1A2 B3C
Is there anyway to maintain the formatting in JOptionPane? Also, I am new to writing programs that read from text files, so if somethings up with my code (i.e. java conventions) ...
I am currently working on a project that can save text from a JTextArea and also open that same saved text. The problem I am having is that when I open the saved text file it is no longer formatted.
How the file looks before saving/closing:
public class HelloWorld{
System.out.println("Hello World!");
}
How the file looks after being saved/closed then opened:
public class HelloWorld{ System.out.println("Hello World!");}
When I save the file I'm actually saving the entire thing to a single string. When I do this the String eliminates all tabbed spacing and pushes all characters to one single line.
The only ideas I had for fixing this were to either somehow use Format in the String class or record every time user tabs and add to the String.
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 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.

private class ButtonListener implements ActionListener{
public void actionPerformed (ActionEvent event)

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.

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

private JButton btnDetermine, btnClear;
private JTextField txtNumber, txtFactors, txtPrime;
private JLabel lblNumber, lblFactors, lblPrime;
private JPanel pnlNumber, pnlNumber1,
[Code] ....

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.

A complex number is defined as z=a+i*b, where a is the real part, and b is the imaginary part. In other words, in order to define a complex number, we need the two floating numbers a and b. Write methods that perform for each of the following operations with complex numbers z1 = a1 + i*b1, and z2 = a2 + i*b2:
Addition: z1 + z2=(a1+a2) + i*(b1+b2)
Subtraction: z1 - z2=(a1-a2) + i*(b1-b2)
Multiplication: z1*z2 = (a1*a2 - b1*b2) + i*(a1*b2 + b1*a2)
Division: z1/z2 = (a1*a2 +b1*b2)/(a2^2 + b2^2) + i*(b1*a2 - a1*b2)/(a2^2 + b2^2)
Create a test program that asks for the real and imaginary parts of two complex numbers from the user, and displays the results of the four operations, writing the formula as shown above, and replacing the a1, a2, b1 and b2 with the numbers entered by the user.The professor used the incorrect complex number equations and has notified the students of his error. I have run into a few problems thus far.
1. I'm not sure how to use floating numbers with the Math.pow(double, double) function, since its requires doubles!? So instead of using floating numbers, I've knowingly switched them all to double in order to see if the code itself is working properly for the purposes of this forum. Is there a way that I can modify this function so that it will work for floating numbers?
2. Regarding the division method, an error stating that c and d have not been initialized and I'm not sure how to change it because the other calculation methods work fine. Why do I need to initialize c and d in the division method and not the others?
3. Am I on the right path? I have surfed the web to see how others completed the program and they all appear very different than mine...
