Solved InventoryClickEvent: How can I get the new item?

I try to make a plugin where I need to get the old and the new ItemStack at the InventoryClickEvent.

Example:

in slot 1 is a diamond sword and I have no item to move with my cursor. I click the diamond sword
-> new item: null, old item: diamond sword

in slot 2 is nothing and i have the diamond sword on my cursor. I click the empty slot
-> new item: diamond sword, old item: null


Can someone say me how I can get the new and the old item in InventoryClickEvent? I only know that I get the old one with

Code:

e.getInventory().getItem(e.getRawSlot())

and the one on the curser (the new one -> the old one from the slot)

Code:

e.getCurrentItem()

And sorry if my Englisch is not the best one

I solved it!
Now I save the old item instantly and the new one after 1 tick delay

Code:

Bukkit.getScheduler().scheduleSyncDelayedTask(
            Main.getInstance(), new Runnable() {
            @Override
            public void run() {
                newItem = e.getInventory().getItem(e.getRawSlot());
            }
        }, 1L);

Why not just use event#getCursor to get the item on the cursor?
