I'm trying to create a different actionPerformed when Shift is held down while pressing a JButton, but when I use:
event.isShiftDown;
my program does not compile because it does't recognise it.

Basically you need to bitwise-and the ActionEvent#getModifiers result
if ((e.getModifiers() & InputEvent.SHIFT_MASK) != 0) {
// Shift is down...
}

As an alternative to checking the event modifiers directly, consider using a different Action for each state of the shift key. You can supply the desired mask to the KeyStroke used in your key binding, as outlined here. A related example using getMenuShortcutKeyMask() is shown here.
