A little help with getting varaibles from another class

hey,
so i have these two classes and they both are GUI's. the first main class is called GUI (very original) and he second is called adder. so when i click a button on GUI it creates and shows the adder GUI wich gets user input, when the user clicks the done button on the adder gui it does this this:
      * method to dispose of the gui without deleting the object
     public void close()
         addWindow.dispose();
      * method for when the done button is clicked
     private void buttonClicked()
     personName = ename.getText();
        personPin = epin.getText();
        personAddress = address.getText();
        close();
    }then we go to the GUI class and do this:
public void addPart2()
        lm.addElement(adder.personName + "-" + adder.personID + "-" + adder.personAddress + "-" + adder.personPin );
    }(all varibless are public by the way), so when i go and have a method directly call adderPart2 right after the adder gui is closed it comes up with all variables bieng null, but if i go in and manualy call the method without doing anything else it works, can anyone explainthis and/or hellp me?

so does anyone have a solution for this problem or at least know what is happening?
Thanks a-bundle,

Calling a TextFields get method from another class as a String

This is my first post so be kind....
I'm trying to create a login screen with Java Studio Creator. The Login.jsp has a Text Field for both the username and password. JSC automatically created get and set methods for these.
public class Login extends AbstractPageBean
private TextField usernameTF = new TextField();
public TextField getUsernameTF() {
return usernameTF;
public void setUsernameTF(TextField tf) {
this.usernameTF = tf;
private PasswordField passwordTF = new PasswordField();
public PasswordField getPasswordTF() {
return passwordTF;
public void setPasswordTF(PasswordField pf) {
this.passwordTF = pf;
My problem is in trying to call these methods from another class and return the value as a string.
Any help on this matter would be greatly appreciated.

the method returns the textfield, so you just need to get its text
import java.awt.*;
class Testing
public Testing()
    Login login = new Login();
    System.out.println(login.getUsernameTF().getText());//<----
public static void main(String[] args){new Testing();}
class Login
private TextField usernameTF = new TextField("Joe Blow");
public TextField getUsernameTF() {
    return usernameTF;
}

Problem getting arraylist from another class

I am trying to call information about an arraylist from another class. I am using this code to call the size of an arraylist:
import java.io.*;
public class Test
    public static void main(String argv[]) throws IOException
Echo03 thing = new Echo03();
int y=thing.value();
System.out.println(y);
Echo03 thing2 = new Echo03();
int x=thing2.percent.size();
System.out.println(x);
}from another file which starts like this:
public class Echo03 extends DefaultHandler
static ArrayList<String> percent = new ArrayList<String>();
static ArrayList<String> text = new ArrayList<String>();
int a;
public int value(){
     return percent.size();
public static void main(String argv[]) throws IOException
    {The second file is based on an example piece of code from the Java website. I havent posted the whole thing, but if it is relevant then please ask.
Anyway when I run Echo03 by itself, the arraylist has a size of 2. But when I run it from the Test file, it says a size of 0. Is this because the data is not being transferred between the classes? Or is the Echo03 program not executing (and hence the arraylist is not filling up)?
How can I fix this? I have tried 2 ways of calling the data (As seen in my Test file). Neither work.

I didnt post the full bit of the code for the second one. Here it is:

This is a classic problem that coders run into when trying to get their head around object-oriented programing. Since you have a class that should be modeled after a real world object, as far as that object is concerned, no one else needs to know the details of it - without asking nicely. This is where you should set up some getters and setters, which are methods that allow fields in a class to reveal themselves or allow their states to be changed in a orderly fashion.
There are a number of fields that never need to be known outside of the class. Then there are some fields you would like to let people know about, but don't want them to have the ability to change them. In the example below, there are to getter methods allow return of the necessary fields. If you made these public, there is a possibility that someone utilizing this field may change it outside of its intended use, or access them without them being ready for public consumption.
Class test {
//These private variables are only visible from the class
private int grade1 = 0;
private int grade2 = 0;
private int grade3 = 0;
private float average = 0;
private int gradeboost = 0;
//This method sets the gradeboost field to one desired by the instructor
void setboost(int boost) {
gradeboost = boost;
//These methods accept test scores and compute the average for three test
//Notice that the calculated average may not be the true average of the three test scores
//because of the possibility of gradeboost calculation being greater than 1
void test1(int score) {
         grade1 = score;
         average = (grade1 + grade2 + grade3 + gradeboost)/3;
void test2(int score) {
         grade2 = score;
         average = (grade1 + grade2 + grade3 + gradeboost)/3;
void test3(int score) {
         grade3 = score;
         average = (grade1 + grade2 + grade3 + gradeboost)/3;
//This is a getter method, which provides read access to the private variable average
//If someone just had public access to the grades and wanted to take their own average
//They would miss how the gradeboost field affects the final outcome.
float getAverage() {
    return average;
//Here is a getter method, which accepts an argument to determine which test score to return
//Notice that this isn't the true testscore, but it has been modified by the gradeboost field.
//If the user had public access to the true testscore, it wouldn't take into account the gradeboost calculation!!
//This is how a getter can control exactly what a user has access to.
float get testScore(int test) {
float testresult = 0;
if (test = 1) {
       testresult = (grade1+ gradeboost) / 3;
if (test = 2) {
       testresult = (grade2+ gradeboost) / 3;
if (test = 3) {
       testresult = (grade3+ gradeboost) / 3;
return testresult;
}

Help with getting values from request. Very Strange!!

Hello,
My very strange problem is the following.
I have created three dynamic list boxes. When the user select
the first list box, the second becomes populated with stuff
from a database. The third becomes populated when the second
is selected. Now, I have used hidden values in order for
me to get the selected value from the first listbox. The
following code is my first listbox:
<SELECT NAME="resources" onChange="document.hiddenform.hiddenObject.value = this.option [this.selectedIndex].value; document.hiddenform.submit();">
<OPTION VALUE =""> Resource</OPTION>
<OPTION VALUE ="soil"> Soil </OPTION>
<OPTION VALUE ="water"> Water </OPTION>
<OPTION VALUE ="air"> Air </OPTION>
<OPTION VALUE ="plants"> Plants </OPTION>
<OPTION VALUE ="animals"> Animals </OPTION>
</SELECT>
I use the getRequest method to get the value of hiddenObject.
At this time I am able to get the value of hiddenObject to populate
the second list box.
But, when the user selects an item from the second list box
and the second form is also submitted,
I lose the value of hiddenObject. Why is this??
The code to populate my second listbox is the following:
<SELECT NAME ="res_categories" onChange="document.hiddenform2.hiddenObject2.value = this.options[this.selectedIndex].value; document.hiddenform2.submit(); ">
<OPTION VALUE ="" SELECTED> Category</OPTION>
Here I access a result set to populate the list box.
Please help!!

Form parameters are request-scoped, hence the request.getParameter("hiddenObject"); call after the submission of the second form returns a null value because the hiddenObject parameter does not exist within the second request.
A solution would be to add a hiddenObject field to your second form and alter the onChange event for res_categories to read
document.hiddenform2.hiddenObject.value=document.1stvisibleformname.resources.option[document.1stvisibleformname.resources.selectedIndex].value;
document.hiddenform2.hiddenObject2.value = this.options[this.selectedIndex].value;
document.hiddenform2.submit();You will then come across a similar problem with your third drop-down if indeed you need to resubmit the form...
A far better approach would be to create a session scoped bean, and a servlet to handle these requests. Then when the servlet is called, it would set the value of the bean property, thus making it available for this request, and all subsequent requests within the current session. This approach would eliminate the need for the clunky javascript, making your application far more stable.

I am developing in Netbeans. If I try to remove the static keyword from main(), netbeans canno't find a main to run. I have created the User class.
Here is the main again to show what I have done.
public static void main(String args[]) throws SQLException {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
User user = new User();
JFrame frame = new JFrame();
JTextField userName = new JTextField();
JTextField passWord = new JTextField();
Object[] options = {"OK","CANCEL"};
Object[] msg = {"UserName:", userName, "Password:", passWord};
final JOptionPane op = new JOptionPane(msg, JOptionPane.PLAIN_MESSAGE, JOptionPane.OK_CANCEL_OPTION){};
JDialog dialog = op.createDialog(frame, "Please Login");
dialog.show();
int result = JOptionPane.OK_OPTION;
try {
result = ((Integer)op.getValue()).intValue();
}catch(Exception uninitializedValue){}
if(result == JOptionPane.OK_OPTION) {
String userID = userName.getText();
String passID = passWord.getText();
user.setName(userID);
user.setPassword(passID);
if(!userID.equals("") && !passID.equals("")) {
//Auth.setUserName(userID);
//Auth.setPassword(passID);
new Main().setVisible(true);
}else {
// user cancelled
This set's the variables
Here is the beginning of the evt that I am using to try and get the data.
private void selButtonActionPerformed(java.awt.event.ActionEvent evt) {
Connection conn = null;
Statement stmt3 = null;
Statement stmt4 = null;
ResultSet rset3 = null;

String ustat = null;
String manager = null;
String dept = null;
String Add = "Add";
String Update = "Update";
String groupID = "9999";
Vector columnNames = new Vector();
Vector data = new Vector();
User user = new User();
String User = user.getName();
System.out.println(User);
String Manager_info[] = {"managerindex", "managers", "managername"};
String Account_info[] = {"acctypeindex", "acctype", "acctypedesc"};
String Group_info[] = {"groupnum", "groups", "groupcode"};
String System_info[] = {"systemindex", "systems", "systemname"};

SimpleDateFormat formatter = new SimpleDateFormat("dd-MMM-yy");
String today = formatter.format(myDate);
String [] str = {
"EmpID", "Account", "System", "Type", "Status", "UserID", "Group"
This gives me a null on the println, how can I get the data that was entered in main()?
Thanks,

Help with getting links from HTML page

Hello all. I found the sun tutorial for getting HREF values from a tags in an HTML document at <http://java.sun.com/developer/TechTips/1999/tt0923.html>. My question now is how would a person add the ability to get the text of the link to this code?
For example:
Provided the HTML code:<a href="link.html">example</a>Returned is: href=link.html text=example

I think the TechTip you've linked too is quite old (1999). I would write a simple SAXParser that uses TagSoup (http://www.ccil.org/~cowan/XML/tagsoup/) as its input source. In your handler, simply set a flag and reset a StringBuffer to collect the contents of any <a>...</a> element. Simplified:
    public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
        if ("a".equals(localName)) {
            currentHref = attributes.getValue("href");
            if (currentHref != null && currentHref.length() > 0) {
                inLink = true;
                //reset the string buffer
                buffer.setLength(0);
    public void characters(char[] ch, int start, int length) throws SAXException {
        if (inLink) buf.append(ch, start, length);
    public void endElement(String uri, String localName, String qName) throws SAXException {
        if ("a".equals(localName) && inLink) {
            inLink = false;
            //add link to the stack
            links.add(new Link(currentHref, buffer.toString()));
    }Completely untested, of course... .Good luck...

Need help with custom event from Main class to an unrelated class.

Hey guys,
I'm new to Flash and not great with OOP. I've made it pretty far with google and lurking, but I've been pulling my hair out on this problem for a day and everything I try throws an error or simply doesn't hit the listener.
I'm trying to get my Main class to send a custom event to an unrelated class called BigIcon. The rest of the code works fine, it's just the addEventListener and dispatchEvent that isn't working.

Alright, this compiles, gives me no errors, shows my 'book' and 'flowers' icons perfectly when ran, and prints 'addEventListener' to the output window as expected. I get no errors when I press the button, 'dispatchEvent' is output (good), but the 'twitchUp' function is never called and 'EventTriggered' is never output.
How do I get the 'twitchUp' event to trigger?

Need a little help with a Jbutton not working out the way I planned

The following code is to fulfill an assignment I am working on. The problem I am having is with the btnCalc. For some reason when the button is used, the results I get is from another button. I think the variables are set right for the program to function properly but I am really hung up on this. Do anyone have any suggestions?

}

This portion to be exact. All the buttons work for me except this one. I need to calculate user input and also use the fixed data that can be found in the dblTrmLoanRate array. When I choos to use user input instead, the program either crashes or for some reason uses the year7InterestRateBtn instead.
               if (command == btnCalc)
                    //dblLoanAmount = Double.parseDouble(txtTotalMort.getText() ); // Loan amount
                    //interestRate = Double.parseDouble(txtInterestRate.getText() ); // /100 )/ 12; // Devides rate
                    intRate = (Double.parseDouble(txtInterestRate.getText() )/100 )/ 12;
                    //int intYearsMonths = Integer.parseInt(txtYearsInput.getText() );// * 12; //Multiplies loan length
                    int months = Integer.parseInt(txtYearsInput.getText() )* 12;
I was going to leave out the remed portion but thought it might help you with the navigation. I am sorry I did not use code tags, but I am going to go find out what those are and use them in the future.

Need a little Help with my new xfi titanium

+Need a little Help with my new xfi titanium< A few questions here.
st question? Im using opt out port on the xfi ti. card and using digital li've on a windows 7 64 bit system,? I would like to know why when i use 5. or 7. and i check to make sure each speakear is working the rear speakers wont sound off but the sr and sl will in replace of the rear speakers. I did a test tone on my sony amp and the speaker are wired correctly becasue the rear speakers and the surrond? left and right sound off when they suppose too. Also when i try to click on? the sl and sr in the sound blaster control panel they dont work but if i click on the rear speakers in the control panel the sl and sr sound off. Do anyone know how i can fix this? So i would like to know why my sl and sr act like rears when they are not?
2nd question? How do i control the volume from my keyboard or from windows period when using opt out i was able to do so with my on board? sound max audio using spidf? Now i can only control the audio using the sony receiver.
Thank you for any help..

I'm unsure about the first question. Do you even have a 7. system and receiver? If you just have 5., you should be able to remap the audio in the THX console.
I do have a sony 7. reciever str de-995 its an older one but its only for my cpu. At first i didnt even have THX installed because it didnt come with the driver package for some reason until i downloaded the daniel_k support drivers and installed it. But it doesnt help in anyway.
I have checked every where regarding the first question and alot of people are having problems getting sound out of there rear channels and the sound being re-mapped to the surround right and the surround left as if there rear left and rear right.
I read somewhere that the daniel_k support drivers would fix this but it didnt for me and many others.
For the second question i assumed it would be becasue of the spidf pass through and that my onboard sound card was inferior to the xfi titaniums. But i wasnt sure and i was hopeing that someone would have a solution for that problem because i miss controlling the volume with my keyboard.

Getting a variable value from another class

Is there any way to get the value of a variable from another class? I have a file that calls another that does some checking then gives a true or false. The place the checking is done is inside an ActionListener I want to use that value in the file that calls the second. Any help would be great.

in 'another class', implement a method,
public boolean isCheckedOutOK( Object obj )
do the comparison in that method (use a suitable argument)

Best way To get data from another application using NDDE lbrary

My vb.net application gets data from another application using NDDE Library. I got stocks prices (open,high,low,close,volume,change......(about 15 records for each stock)) (about 200 stocks) . I don't know if there is a problem in my code.
This is my code:
l : is the list of stocks.
This Sub connects to server and requests the data :
Public Shared Sub GetQuotes()
Try
client1 = New DdeClient(server, topic)
client1.Connect()
For i As Integer = 0 To l.Count - 1
client1.StartAdvise("QO." & l(i).t & ".TAD$last", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$open", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$high", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$low", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$pclose", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$volume", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$date", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$time", 1, True, 60000)
Next
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
and then I get the data from Client_advise sub (called each time a value changed )and fill the list. What I know is that client advise gets only one record for single stock each time is called..
Example: for stock AAPL. 1st time enters client_Advise I get open price for AAPL, 2nd time I get high price for AAPL,3rd time I get low price..... and I update the value in the List (l)
This the client_Advise Sub:
Private Shared Sub client1_Advise(ByVal sender As Object, ByVal e As NDde.Client.DdeAdviseEventArgs) Handles client1.Advise
For q As Integer = 0 To l.Count - 1
If l(q).t = w(1) Then
Dim item() As String = e.Item.Split("$")
If l(q).Open = "#" Then
l(q).Open = "0"
End If
If l(q).hi = "#" Then
l(q).hi = "0"
End If
If l(q).lo = "#" Then
l(q).lo = "0"
End If
If l(q).Close = "" Or l(q).Close = "#" Then
l(q).Close = "0"
End If
If l(q).pclose = "#" Then
l(q).pclose = "0"
End If
If item(1) = "open" Then

Am I doing something wrong which inreases CPU usage to 80 or 90 % ?
Thanks in advance.

Hi MikeHammadi,
According to your description, you'd like to get data from another app using NDDE library.
When using the NDDE library, the CPU usage is high. As the NDDE library is third-party library, it is not supported here. I suggest you checking if the problem is caused by the NDDE library.
If you'd like to get data from another app. I suggest you could save the data in the dataBase, and then read it in another application if necessary.
If you have any other concern regarding this issue, please feel free to let me know.
Best regards,
Youjun Tang
