JPanel content change with MouseClicked

Question

Here is my very simple question.
I create a JFrame, and a JPanel in it, and create a content via toAdd class which implements MouseListener.
What can I do to refresh the content of JPanel when MouseClicked?
I tried many things but since they did not work, may be for now, I should only ask, here is the code:
package jpanel;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class App1 {
    private static class toAdd extends JPanel implements MouseListener{
        public void paint(Graphics g){
            super.paintComponent(g);
            g.drawString("deneme", 20, 50);
        public void mousePressed(MouseEvent evt){}
        public void mouseReleased(MouseEvent evt){}
        public void mouseClicked(MouseEvent evt){
        // my question is related to this part.
        public void mouseEntered(MouseEvent evt){}
        public void mouseExited(MouseEvent evt){}
    public static void main(String[] args){
        toAdd toAdd = new toAdd();
        JPanel content = new JPanel();
        content.setLayout(new BorderLayout());
        content.add(toAdd, BorderLayout.CENTER);
        JFrame window = new JFrame("Platform");
        window.setContentPane(content);
        window.setSize(100, 200);
        window.setLocation(100, 100);
        window.setVisible(true);

Like this perhaps?
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class App1 {
    private static class toAdd extends JPanel implements MouseListener{
        public toAdd() {
            addMouseListener(this);
        private int wordindex = 0;
        private String[] words = { "not clicked", "clicked" };
        public void paint(Graphics g){
            super.paintComponent(g);
            g.drawString(words[wordindex], 20, 50);
        public void mousePressed(MouseEvent evt){}
        public void mouseReleased(MouseEvent evt){}
        public void mouseClicked(MouseEvent evt){
            wordindex = wordindex == 0 ? 1 : 0;
            invalidate();
            repaint();
        public void mouseEntered(MouseEvent evt){}
        public void mouseExited(MouseEvent evt){}
    public static void main(String[] args){
        toAdd toAdd = new toAdd();       
        JPanel content = new JPanel();
        content.setLayout(new BorderLayout());
        content.add(toAdd, BorderLayout.CENTER);
        JFrame window = new JFrame("Platform");
        window.setContentPane(content);
        window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        window.pack();
        window.setSize(100, 200);
        window.setLocation(100, 100);
        window.setVisible(true);
