ich weis das ich laut fehlermeldun meinen block nicht zu einer kiste casten darf, aber wie soll ich das sonst anstellen das ich an den inhalt komme?

Code:

@EventHandler
    public void onInterackt(PlayerInteractEvent e){
       
        Block b = e.getClickedBlock();
        Player p = e.getPlayer();
       
        if (b.getType() == Material.WALL_SIGN ) {
           
            //Sign s =  (Sign) b;
           
            Location locS = b.getLocation();
            Location locK = new Location(locS.getWorld(), locS.getX(), locS.getY()-1, locS.getZ());
           
            Block b2 = locK.getBlock();
           
            if (b2.getType() == Material.CHEST){
               
                Chest c = (Chest) b2;
                Inventory inv = c.getBlockInventory();
               
                p.sendMessage(inv.toString());
               
            }
           
        }
}

ich hoffe ihr könnt mir helfen.

Hat sich erledigt. fehler ist gefunden

public interface Chest extends BlockState, InventoryHolder

Block b;
Chest c = (Chest) b.getState();
