    Default Having trouble storing variable from JTextField

    Hi,
    I want the user to input their name etc into a Jtextfield and it will return their details, but I keep getting an error saying cannot find symbol getText()
    Here is my code
    public void deliveryWindow(){
     
                JFrame newFrame = new JFrame("Delivery Details");
     
                Container pane = getContentPane();
                newFrame.setLayout(new FlowLayout());
                newFrame.setSize(new Dimension(250, 250));
                //newFrame.getContentPane().add(panel);
                newFrame.setLocation(300,300);
                newFrame.setSize(250,250);
                newFrame.setVisible(true);
                JButton submitButton = new JButton("submit");
                newFrame.add(submitButton);
                ButtonEventHandler handler = new ButtonEventHandler();
                submitButton.addActionListener(handler);
     
                JPanel name = new JPanel();
                JLabel nameLabel = new JLabel();
                nameLabel.setText("Name :");
                JTextField nameField = new JTextField(15);
                String deliveryName = nameField.getText();
                name.add(nameLabel);
                newFrame.add(nameLabel);
                newFrame.add(nameField);
     
     
                JPanel address1 = new JPanel();
                JLabel addressLabel = new JLabel();
                addressLabel.setText("House :");
                JTextField address1Field = new JTextField(15);
                String deliveryAddress1 = address1Field.getText();
     
                address1.add(addressLabel);
                address1.add(address1Field);
                newFrame.add(addressLabel);
                newFrame.add(address1Field);
     
                JPanel street = new JPanel();
                JLabel streetLabel = new JLabel();
                streetLabel.setText("Street :");
                JTextField streetField = new JTextField(15);
                String deliveryAddress2 = streetField.getText();
                street.add(streetLabel);
                street.add(streetField);
                newFrame.add(streetLabel);
                newFrame.add(streetField);
     
                JPanel phone = new JPanel();
                JLabel phoneLabel = new JLabel();
                phoneLabel.setText("Phone :");

    Can you maybe tell us at what line the error is located?

    * EDIT *

    If the problem is in the line:

    			String name1;
    			name1 = nameField.getText();

    Are you sure the script can access: nameField
    Looking at your code I don't think your script knows what this "nameField" is.

    Thanks for your reply, this is where I get the error
    name1 = nameField.getText();

    How do I go about getting my script to access the nameField?
    Thanks

    Make sure the variable definition is in scope (within same pair of {}s) where you are using it.

    Does your program also gives out those huge error messages?
    Like, error: cannot find symbol method getText()
    and then below that is writen what line etc etc.

    (I will be back later, need to walk to the train now....)

    Thanks for the replies. I have changed my code around a bit.
    Inside in pizzaMenu(), I have put
    deliveryName = nameField.getText();
    Inside in public void actionPerformed(ActionEvent e)
    I have put:
    String name1;
    name1 = deliveryName;
    but when I go to enter my name, its displayed as null.

    Where is the code that shows that the value of the variable is null?

    Why use the variable: name1? Why not use deliveryName?

    That appears on the showMessageDialog screen when I enter the name in the nameField and then click submit on the JButton.

    What happens if you remove the variable: name1 and use deliveryName instead?

    Try debugging the code by adding a println that prints out the value that returned by the getText() method so you can see what the code is doing.
    Is the code getting the value BEFORE the user enters it? If you see the println's print out before the user enters anything, then that is your problem. You need to wait until the user has entered something BEFORE calling getText().

    Sorry but java is not my strongest area, how would I go about doing that? Where would I place the System.out.println()?

    Immediately after the variable gets a value assigned to it.

    Assign variable a value
    print value of the variable

    Are you printing the value AFTER the user has entered some data?
    Can you see the printed output before the user enters anything?
