Solved Cast Inventory to Chest

Hej everyone,

Im currently working on chests which will refill themselve when they are empty.
For that I need to check if the chest is clear and if so, refill it. As Im working with a public static classes for setting the items into the chest, I need to cast the Inventory to a Chest but java gives me an error.
Any idea how to solve my problem?

Code:

//Refill
    @EventHandler
    public void onCloseChest(InventoryCloseEvent e) {
     
        if(e.getPlayer() instanceof Player) {
         
            Player p = (Player) e.getPlayer();
         
            if(e.getInventory().getHolder() instanceof Chest) {
             
                Chest chest = (Chest) e.getInventory();
             
                if(onEmptyChest(e.getInventory())) {

                    InventoryChest.setItems(chest);
                 
                }
             
            }
         
        }
     
    }

@baenii Get the inventory's holder using Inventory#getHolder(), and then check if it's an instanceof Chest, if so, cast the holder to Chest.

 

@KarimAKL That's what I did here, isn't it?

//EDIT: One sec.. I've just casted the Inventory.

//EDIT EDIT: Casting the Inventory Holder instead of the Inventory actually solved my problem. Thanks!
