Editable issues

I made a java program and can't figure out why my uneditable text can still be edited. I have 2 classes in this program here's the secondary class:
import java.awt.FlowLayout;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JTextField;
import javax.swing.JPasswordField;
import javax.swing.JOptionPane;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JLabel;

public class GUI_two extends JFrame{

    private JTextField item2;
    private JTextField item3;
    private JTextField item4;
    private JPasswordField itempass;
    ImageIcon image = new ImageIcon("star.png");
    public GUI_two(){
    super("Kale");
    setLayout(new FlowLayout());
    item2 = new JTextField(10);
    add(item2);
    item3 = new JTextField("Enter text here");
    item3.setEditable(false);
    add(item3);
    item4 = new JTextField("Can't edit", 20);
    item3.setEditable(false);
    add(item4);
    itempass = new JPasswordField ("Password");
    add(itempass);
    reg = new JButton("Button");
    add(reg);
    Icon b = new ImageIcon(getClass().getResource("Button 2.png"));
    Icon a = new ImageIcon(getClass().getResource("Button.png"));
    custom = new JButton("Custom", a);
    custom.setRolloverIcon(b);
    add(custom);

    thehandler handler = new thehandler();
    item2.addActionListener(handler);
    item3.addActionListener(handler);
    item4.addActionListener(handler);
    itempass.addActionListener(handler);
    reg.addActionListener(handler);
    custom.addActionListener(handler);

    }

    private JButton reg;
    private JButton custom;

    private class thehandler implements ActionListener{
        public void actionPerformed(ActionEvent event){
            String string = "";
            if(event.getSource()==item2){
                string=String.format("field 2: %s", event.getActionCommand());}
            else if (event.getSource()==item3)
            string=String.format("field 3: %s", event.getActionCommand());
            else if (event.getSource()==item4)
            string=String.format("field 4: %s", event.getActionCommand());
            else if (event.getSource()==itempass)
            string=String.format("itempass is : %s", event.getActionCommand());

            //JOptionPane.showMessageDialog(null, String.format("%s, event.getActionCommand()"));
            JOptionPane.showMessageDialog(null, string);
        }
            }

}

here's the main class:
import javax.swing.JOptionPane;
import javax.swing.JFrame;

public class Kale_GUI {

    public static void main(String[] args) {
        String fn = JOptionPane.showInputDialog("Enter first number");
        String sn = JOptionPane.showInputDialog("Enter second number");
        int num1 = Integer.parseInt(fn) ;
        int num2 = Integer.parseInt(sn) ;
        int sum = num1 + num2;
        JOptionPane.showMessageDialog(null, "The answer is "+sum, "The title", JOptionPane.PLAIN_MESSAGE);

         GUI_two kale = new GUI_two();
          
         kale.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
         kale.setSize(500,500);
         kale.setVisible(true);
    }

}
