public KeyboardPanel() {
   addKeyListener(new KeyAdapter() {
     @Override
     public void keyPressed(KeyEvent e) {
         if(e.getKeyCode()== KeyEvent.VK_1){
             super.keyPressed(e);
             add(new JLabel(image1, JLabel.CENTER));
             validate();

         if(e.getKeyCode()==KeyEvent.VK_7){
             super.keyPressed(e);
             add(new JLabel(image4,JLabel.CENTER));
             validate();
         }

Na dugme se dodaje ActionListener na sledeći način:

JButton prikazi=new JButton(“Prikazi”);
prikazi.addActionListener(new ActionListener() {
[CODE]@Override
public void actionPerformed(ActionEvent e) {
   System.out.println("Usao u actionPerformed");

//kod koji zelis da se izvrsava na klik
}
});[/CODE]
