Solved Death Message

So I made a death message, and I want it to show what Item the player was killed with. When someone kills me with a unnamed item it says null. How do I make it show the name?

Code:

    @EventHandler(priority=EventPriority.HIGHEST)
    public void onPlayerJoin(PlayerDeathEvent event) {
        Player player = event.getEntity().getPlayer();
        Player killer = event.getEntity().getKiller();
       
        event.setDeathMessage(player.getName() + " was killed by " + killer.getName() + " with " + killer.getItemInHand().getItemMeta().getDisplayName());
       
    }

Deleted Message.

• Killer may be null (do checks to prevent a NPE)
• Player may not always have an item in their hand (which would be null)
• The display name is only used if the item was renamed. Else it would return null

How do I make it display the item name?

 

@bubblefat_ In my CustomDeathMessages plugin, I just had it display the Material enum name. Not perfect because some material names aren't what the actual default item name is. There is this but I haven't used it:
