How to get text from same Text Field used multiple times in Java Swing

I’m trying to get text from a JTextField iterated through my code (apparently, I can’t add a different text field from a button). Here’s what the “Add Items” button do:

addButton.addActionListener(new ActionListener() {
    public void actionPerformed(java.awt.event.ActionEvent e) {
        tf = new JTextField("Name",20);
        tfv = new JTextField("Value", 7); 
        
        p.revalidate();
        p.repaint();   
        
        p.add(tf);
        p.add(tfv);
    }
});

It adds two new text fields in the panel using FlowLayout. Now, I want to get the text given by the user from text fields with each one assigned to a different variable or maybe into an ArrayList by clickin the “OK” button but the getText() method doesn’t seem to work.

okButton.addActionListener( e -> {
    
        String txt = tfv.getText(); //only captures the text from the last field in the panel

});

Can’t seem to think of anything right now.

Answer

in this code when you are reinitializing tf and tfv in addButton you lost the reference to previous defined textfiels

tf = new JTextField("Name",20);
tfv = new JTextField("Value", 7);

so to solve this problem you need to define an ArrayList to hold reference to all defined textfields and then you can access to all of them:

ArrayList<JTextField> arrayNames  = new ArrayList<JTextField>();
ArrayList<JTextField> arrayValues = new ArrayList<JTextField>();

addButton.addActionListener(new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent e) {
        tf = new JTextField("Name",20);
        tfv = new JTextField("Value", 7); 
        
        p.revalidate();
        p.repaint();   
        
        p.add(tf);
        p.add(tfv);

        arrayNames.add(tf);
        arrayValues.add(tfv);
    }
});

accessing

okButton.addActionListener(new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent e) {
        for (JTextField txtValue : arrayValues) {
            System.out.println(txtValue.getText());
        }
    }
});
