keyListener how to modify object which called it?

Hi im using keylistener for my buttons but i cant work out how to determin inside the keylistener, which button is being called.
because once i know which button is being called i wish to change its background.

Code:

---

       
          for (int i=0; i < colorShow.length;i++){
            colorShow[i] = new JButton();
            colorShow[i].setPreferredSize(new Dimension(20,20));
            colorShow[i].setBorder(BorderFactory.createLineBorder(Color.black));
            colorShow[i].addKeyListener(this);
            dataPanel.add(colorShow[i]);

        }

---

Code:

---

   
@Override
  public void keyPressed( KeyEvent e ) {}
  @Override
  public void keyReleased( KeyEvent e ) { }
  @Override
  public void keyTyped( KeyEvent e ) {

    //code here to change background when any key is pressed
      }

---

figured it out

e.getComponent().setBackground(Color.red);

Someone in this forum told me before that keylistners is not the correct approch to set shortcut
keys since key lisnteners are use in AWT before Swing exist. And she advised to use KeyBinding instead.
