如何检查按下的键是否是Java KeyListener中的箭头键？

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;     }}
