Can you help me please

To Cambell: I am using a text Area where I can see the error message because if i use a message box it will pop up everytime i release the button thats why i dont use a message box

Sorry guys if I was not clear as I am a new user
my problem is not a design error I hope this time I can be more clear
1. all this 3 form are tables in my database and i have to store each field to their tables which are customers, booking and taxreturns
2. my customer form is the one for starting the program where I enter the customer details.
3. I can insert update delete and search for a customer
4. The second form is for making a booking to do the tax return and the third form if for making the calculation or the tax return

I have no problem so far working with the data base all is good
what i need is:
from the Customer Form I want CustomerTFN and Surname to be display in the other forms. for example if you can see my screen shots. I have the same CustomerTFN and Surname in my Booking Form how can I display them from the Customer Form. If i would do this program in Visual Basic I can make a module or global declaration and end of problem but in Java I dont know how to do it.
i will show a bit of my code if help:
1.-From customer class
public class CustomerClass { //this part CustomerTFN with getter and setter public String CustomerTFN,Surname,Firstname,DOB,Gender,Stno, Stname,Suburb,Postcode,Phoneno; public String getCustomerTFN() { return CustomerTFN; } public void setCustomerTFN(String CustomerTFN) { this.CustomerTFN = CustomerTFN; }
2.-from CustomerForm(Design)
tfCustomerTFN.addKeyListener(new KeyAdapter() // in here i validate the field and SET the customerTFN { public void keyReleased(KeyEvent evt) { String txt = tfCustomerTFN.getText(); Pattern pattern = Pattern.compile("[0-9]{3}[-][0-9]{3}[-][0-9]{3}"); Matcher matcher = pattern.matcher(txt); if (matcher.matches()) { tfCustomerTFN.setText(matcher.group()); tfSurname.setEditable(true); taError.setText(""); clsCustomer.setCustomerTFN(txt); //IM SETTING THIS FIELD FROM HERE so i can get this string with the get method

3.- what i need to do is this in the third form which is Booking Form

JTextField tfCustTFN = new JTextField("");

this bit is from the booking form i need to display the customerTFN from the CustomerCLass as i got the set and get method but if i can have a global declaration i can call this methods from any class inside the project

please can anyone see my screen shots attached here and in the customer form i have text fields for CustomerTFN and Surname and what i want is to show them in the second form which is the booking form I think a Module declaration for those field would be the solution but i dont know how to do that I will appreciate any help thank you

Here is a great site that lets you test a regular expression; I use it whenever I have a problem like this. However: you need to find a way to articulate the rules for your text validation -- completely, precisely, and unambiguously. Otherwise you will just be guessing.

thank you it works now

HI I AM DEVELOPING A TAX RETURN PROGRAM AND I GOT STUCK IN THE VALIDATION OF ONE FIELD WHICH IS FOR THE SURNAME I FIND IT HARD TO GET THE CORRECT SYNTAX I TRIED THIS

tfFullName.addKeyListener(new KeyAdapter()
{
public void keyReleased(KeyEvent evt)
{
String text= tfFullName.getText();

Pattern pattern = Pattern.compile("['a-zA-Z][a-zA-Z ']*");

Matcher matcher = pattern.matcher(text);

THIS CODE INSIDE THE PARENTHESIS IS VALID BUT GIVE ME AN UNLIMITED NUMBER OF STRING AND I ONLY NEED FOR ONE OR TWO FOR EXAMPLE I WISH TO VALIDATE
FERGUSON FOR ONE SURNAME AND
VAN VOWEL OR GARCIA MARQUEZ FOR TWO SURNAMES
IT WOULD BE EVEN BETTER IN SOME ONE CAN HELP ME TO GET SPECIAL SURNAMES LIKE
O'Connor
MacDonald
Smith-Henderson
