Question

Can you help me refactor this code:

public void keyPressed(KeyEvent e)     {      if (e.getKeyCode()==39)     {                 //Right arrow key code     }      else if (e.getKeyCode()==37)     {                 //Left arrow key code     }      repaint();  } 

Please mention how to check for up/down arrow keys as well.Thanks!

public void keyPressed(KeyEvent e) {     int keyCode = e.getKeyCode();     switch( keyCode ) {          case KeyEvent.VK_UP:             // handle up              break;         case KeyEvent.VK_DOWN:             // handle down              break;         case KeyEvent.VK_LEFT:             // handle left             break;         case KeyEvent.VK_RIGHT :             // handle right             break;      } }
