Issue with - "cannot find symbol - variable JOptionPane"

need some help, got the below loop and want it to be able to loop by the number input by the input dialog. when i compile it i get an error in BlueJ. the error is "cannot find symbol - variable JOptionPane". Any help. have tried a few things however cannot get this to work at all. any suggestions?
public void numberLoop()
String qA = JOptionPane.showInputDialog(null,"How many times should this be completed (e.g. 1,2,3,4)?","Question",JOptionPane.QUESTION_MESSAGE);
int qA2 = Integer.parseInt(qA);
for (int startNum = 1; startNum <= qA2; startNum++)
System.out.println(startNum + " squared is " + (startNum * startNum));

The cannot find symbol - variable..... error

i am recieving the "cannot find symbol variable getResident" error with the following line of code:
if (Client.getResident=true)
System.out.printf("Your Medicare Levy Contribution is: $%.2f %n", Client.getMedicare());
i cant figure out why, maybe someone else may know and be able to help, i know that with int or double type methods u put parenthesis at the end of the method name, such as;
while((Client.getGrossSalary())<=0)
but i tried that here and it didnt change anything except the errror message.
i have also tried putting parenthesis around the client.getResident, this didnt work either. i checked and made sure that the getResident method DOES in fact exist also.
cheers for any help

I have tried the following:
if (Client.getResident()=true)
if ((Client.getResident=true))
if ((Client.getResident=(true)))
if ((Client.getResident(true)))
and none of these work, most of these alternatives return the error: unexpected type (Resident variable is boolean)

E.getSource()         cannot find symbol - variable e

I'm currently developing a program for course I'm in that needs to allow a user to open a file, scan the information out of it and display the results.
I'm currently stuck on an error that's really confused me. On the line: if (e.getSource() == readButton) {
the compiler displays the following <cannot find symbol - variable e>.
If anyone could advise me as to my mistake I'd be very happy.
   public void readData(){
    this.textArea.setText(""); // clear the text area, ready to append new strings.
    fc = new JFileChooser();
           File file = null;
           FileReader reader = null;
           if (e.getSource() == readButton) {
            int rValue = fc.showOpenDialog(Plotter.this);
            if (rValue == JFileChooser.APPROVE_OPTION) {
                File file = fc.getSelectedFile();
                reader = new FileReader(file);
                log.append("Opening: " + file.getName() + "." + newline);
            else {
                log.append("Open cancelled by user." + newline);
            log.setCaretPosition(log.getDocument().getLength());
            Scanner input = new Scanner(file);
            while (input.hasNextLine()){
         input.close();
    }

I guess you probably didn't see the post previous to yours ;). Just 2 minutes difference;Yes I did read that post. That is what prompted me to say I think they are doing it wrong. OP suggested that the readData method needed the ActionEvent to be passed as a parameter. Whereas I believe the actionPerformed method should be handle the event and the readData method should do just that: read data.
public void actionPerformed(ActionEvent e) {
    if (e.getSource() == readButton) {
        readData();
private void readData() {
    // method just reads the file
    // no need to handle event here
}

wow i simply added the
private StaugIO io = new StaugIO();
into my ServicesArray class and i got the process completed with no errors, thats awesome but what doesnt make sense is this summary of this assignment that i have:
Code a program that will store available services for Dr. Doolittle's Mobile Pet Clinic. Let the user determine the size of the array. Once the array has been populated with service information, display the contents of the array one at a time in separate GUI windows. Screen capture your output to a Word file and submit it with everything else. Use the code on pp 365-367 in the textbook to help you. Assume that the spacing is always double after a period and colon. You may limit your array size to no more than 3 as indicated by the sample output below. Use the sample output to test your array.
PET SERVICE NO. 1
SERVICE CODE: DG-2478
SERVICE: Dog Group I
DESC: DHLPP, Corona, Bordetella, Rabies
TYPE: Vaccine
PRICE: $47.50
PET SERVICE NO. 2
SERVICE CODE: FL-3182
SERVICE: Feline Group I
DESC: FVRCP, FeLV, Rabies
TYPE: Vaccine
PRICE: $46.50
PET SERVICE NO. 3
SERVICE CODE: DG-4682
SERVICE: Dog Spay
DESC: Abdominal surgery to remove the ovaries and/or uterus
(ovariohysterectomy).
TYPE: Surgery
PRICE: $57.50
No where in my code do i even have any of this so how would the user be able to see this? Is this program designed to just display the SERVICE CODE: and then the user types in the DG-4682? etc etc..
I ask this because I cannot view my dialog boxes because when I run the program i get nothing, just process completed, nothing else.

Error: Cannot find symbol: Variable Name

Hi Guys,
I'm having some trouble with a piece of code. The error that I'm getting is:
program.java:17: cannot find symbol
symbol : variable name
location: class program
name.CTI(names[0].charAt(0));
^
My Code is shown here:
import java.io.*;
import java.lang.*;
class program{
     public static void main(String[] args){
          String names [] = {"brian", "stu", "mouse"};
          program name = new program ();
          name.sortArrayStr(names);
          //name.CTI(names[0].charAt(0));
     public void sortArrayStr( String[] names ){
          name.CTI(names[0].charAt(0));
     public int CTI ( char letter ){
          char c = letter;
        int k = (int) c;
        System.out.println("ASCII = " + k + ".");
          return k;
}What I'm trying to do is get the name.CTI method caled from within sortArrayStr. When i call name.CTI from main it works fine, (commented part) but when i try from sortArrayStr I get this problem.
Anyone have any ideas?
Many Thanks

Variable name is a local variable defined in method main, so it can not be referenced by writing name in another method like sortArrayStr.
The good news is, if you want to call CTI from sortArrayStr, just do it:
public void sortArrayStr( String[] names ){
    CTI(names[0].charAt(0));
}

     }I dont understand why I am getting this error, I clearly define the variable.

Yes, but the variable is declared inside a block and so it's local to that block. You can't use it outside its scope, which is the block in which you declared it. Re-read the section of your book about variable scope.

Please help with cannot find symbol error. Been struggling all day :(

Hi all. :)
Writing a game for my phone with KToolbar and have been getting a cannot find symbol error for every variable and method I try to use across Classes. I've looked all over and though it seems a common problem I always either don't understand or can't get working the various solutions. Example of my errors:
C:\...\BTK800i.java:197: cannot find symbol
symbol : variable youSayWhat
location: class HelloCanvas
          youSayWhat=key;
          ^
If I try BTK800i.variable or BTK800i.message I get a new error.
C:\...\src\BTK800i.java:184: non-static method newOrdersSarge() cannot be referenced from a static context
          BTK800i.newOrdersSarge();
          ^
Both these errors apply to both variables and methods. It only happens when I'm using methods/variables of one class in another, am I using public and private incorrectly? It doesn't seem to make a difference if I make variables public or leave them private, I'm trying to get to them with a public method within a private class. Is it something else? I really have no idea. :(
Here's my code, it's long enough to be a tiresome read so I've tried to skip what I know isn't relevant.
public class BTK800i extends MIDlet {
     private Display myDisplay;
     private HelloCanvas myCanvas;
     public int youSayWhat;
        //a whole bunch more skipped here, but I'm fairly certain it's not anything that'll help find a solution
     public BTK800i() {
          paused=false;
public void startApp() throws MIDletStateChangeException {
          if( paused ) {
               myCanvas.repaint();
          else {
               myDisplay=Display.getDisplay(this);
               myCanvas=new HelloCanvas();
               myDisplay.setCurrent(myCanvas);
               myCanvas.setFullScreenMode(true);
               youSayWhat=0;
                       //again with the skipping, more code not related
public void newOrdersSarge() {
//whole bunch of code
//other methods skipped
class HelloCanvas extends Canvas {
     public void keyPressed (int key) {
          youSayWhat=key;
          repaint ();
//skippage
}The stuff I skipped is mainly either more of the same sorta thing or maths/writing to screen stuff.
Thanks alot to anyone who helps. I'm really struggling with this. :(
Dan.

But I have been reading them :(
My next-door neighbour unfortunately is an 80-something married man, but I will go have a looksie about static and instances.
I thought the point of public variables was that other classes could use them, is this wrong?
Also does this mean that to use the variables from my BTK class in the HelloCanvas class I need to first instantiate BTK? I don't understand how that works as the code starts running from the BTK class in the first place :S I guess more reading will help with this.
Thanks very much for replying. :)
Edit:
OK I have read up on it but I don't think I found anything I hadn't read before. I tried to make a new class which I could instantiate to hold all the variables and methods I wanted everything to be able to access, but that went disastrously. Am I right in understanding that there are no global variables in Java? :s

Having issues with "cannot find" and/or "taking too ling to respond".

I have good signal from my internet provider(broadband 3G service), but it seems like lately all I get is "Cannot find website" and/or "Taking too long to respond" errors.
My internet provider has checked their cell towers, I even bought a new broadband card, I've done all the updates on the card, etc.
Monitoring my card signal shows I have excellent service.
Any suggestions????

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.

Unable to compile, cannot find symbol - variable arg

Hi, I'm new to Java. I have tried to compile the following code. but it won't work
public class Testing
public static void main(String[] args)
int size = args.length;
int largest = -9;
for ( int i = 0; i<size; i++ )
if ( arg[i] > largest )largest = arg;
System.out.println("Largest is " +largest);
I have tried adding int x = Integer.parseInt(args[i]);
but the same error code...
Could it be compiler problem?i'm using BlueJ.
Thanks for helping...

It is because you a comparin a String to an int. This won't work. You need to convert your String to and int.
Take a look at this:
public class Testing
    public static void main(String[] args)
            int size = args.length;
            int largest = -9;
            int value;
            for ( int i = 0; i<size; i++ )
                   value=Integer.parseInt(args); //converts the String to an int
if ( value > largest )largest = value;
System.out.println("Largest is " +largest);
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Integer.html
You need to read the API to check what methods you can use. If you have a problem with say a Sting then google for "Java String API" and view the methods in the String class. You need to make yourself familiar with whats available.

Having trouble finding out why i get "cannot find symbol variable textio"

Im trying to write a romanNumeral converter program.
I dont know what else im doing wrong!
Please help me to see and understand what i did wrong!

Please help me to see and understand what i did wrong!You are using something called 'textio'
The compiler doesn't know what that is.
It is telling you exactly that.

Need help with class info and cannot find symbol error.

I having problems with a cannot find symbol error. I cant seem to figure it out.
I have about 12 of them in a program I am trying to do. I was wondering if anyone could help me out?
Here is some code I am working on:
// This will test the invoice class application.
// This program involves a hardware store's invoice.
//import java.util.*;
public class InvoiceTest
     public static void main( String args[] )
     Invoice invoice1 = new Invoice( "1234", "Hammer", 2, 14.95 );
// display invoice1
     System.out.println("Original invoice information" );
     System.out.println("Part number: ", invoice1.getPartNumber() );
     System.out.println("Description: ", invoice1.getPartDescription() );
     System.out.println("Quantity: ", invoice1.getQuantity() );
     System.out.println("Price: ", invoice1.getPricePerItem() );
     System.out.println("Invoice amount: ", invoice1.getInvoiceAmount() );
// change invoice1's data
     invoice1.setPartNumber( "001234" );
     invoice1.setPartDescription( "Yellow Hammer" );
     invoice1.setQuantity( 3 );
     invoice1.setPricePerItem( 19.49 );
// display invoice1 with new data

     System.out.println("Price: ", invoice1.getPricePerItem() );
     System.out.println("Invoice amount: ", invoice1.getInvoiceAmount() );
and that uses this class file:
public class Invoice
private String partNumber;
private String partDescription;
private int quantityPurchased;
private double pricePerItem;
     public Invoice( String ID, String desc, int purchased, double price )
          partNumber = ID;

     if ( purchased >= 0 )
     quantityPurchased = purchased;
     if ( price > 0 )
     pricePerItem = price;
public double getInvoiceAmount()
     return quantityPurchased * pricePerItem;
public void setPartNumber( String newNumber )
     partNumber = newNumber;
     System.out.println(partDescription+" has changed to part "+newNumber);

8 errorsWhat is the problem?... Any help will be appreciated

Read the message. It cannot find the addElement() method on class java.util.ArrayList.
Just consult the javadoc of the class used for details about the class: [http://java.sun.com/javase/6/docs/api/java/util/ArrayList.html].
In the future, those kind of basic compilation errors (and runtime exceptions) rather belongs in the 'New to Java' forum. Those are really trival.

u mean this??Yes, but, it's hard to know how this relates to your problem without seeing compilable code. Your best bet here is not to show your whole program, but to condense your question/problem into a single small class that is compilable by any and all of us, and demonstrates your problem. In other words, a [Short, Self Contained, Correct (Compilable), Example or SSCCE|http://homepage1.nifty.com/algafield/sscce.html] .
Also, when posting your code, please use code tags so that your code will retain its formatting and be readable. To do this, you will need to paste already formatted code into the forum, highlight this code, and then press the "code" button at the top of the forum Message editor prior to posting the message. You may want to click on the Preview tab to make sure that your code is formatted correctly. Another way is to place the tag [code] at the top of your block of code and the tag [/code] at the bottom, like so:
[code]
// your code block goes here.
// note the differences between the tag at the top vs the bottom.
[/code]or
{code}
// your code block goes here.
// note here that the tags are the same.
{code}good luck
