    Default Repressable button in GUI

    This class shows a GUI with a JLabel, a JButton and a JTextField. When klicking the button, an array of Strings in another class randomizes a String from the array and adds it to the textfield in this class. This works fine.

    But I want the button to be repressable. I want the button to get a new randomized String from the array when I press it again, without restarting the program. How do I do?


    import com.sun.j3d.utils.behaviors.vp.WandViewBehavior.ResetViewListener;
    import java.awt.Color;
    import java.awt.FlowLayout;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    import javax.swing.JButton;
    import javax.swing.JFrame;
    import javax.swing.JLabel;
    import javax.swing.JTextField;
     
     
    public class p12NameGenGUI extends JFrame implements ActionListener
    {
     
        p12NamnLista randomp12Namn = new p12NamnLista();
        JButton knapp;
        JLabel textTK;
        JTextField visaNamn;
     
        public p12NameGenGUI()
        {
            textTK = new JLabel("Tryck på knappen för ett slumpat P12 namn!");
            textTK.setForeground(Color.red);
            knapp = new JButton("TRYCK NU");
     
            visaNamn = new JTextField();
            visaNamn.setColumns(10);
     
            this.add(textTK);
            this.add(knapp);
            knapp.addActionListener(this);
            this.add(visaNamn);
     
     
        }
     
     
        public static void main(String[] args)
        {
     
     
            p12NameGenGUI p = new p12NameGenGUI();
            p.setSize(300, 300);
            p.setLocation(200, 300);
            p.setDefaultCloseOperation(EXIT_ON_CLOSE);
            p.setLayout(new FlowLayout());
            p.setVisible(true);
        }
     
        public void actionPerformed(ActionEvent e)
        {
     
            visaNamn.setText(randomp12Namn.toString());
     
        }
    }//class end

    How is the button not "repressable"? What happens when you press it again?

    When posting code, make sure you use the code or highlight tags. I did it for you this time, but please be more mindful in the future.
