    public void ItemDrop(PlayerDropItemEvent event){
        Player player = event.getPlayer();
        if(event.getItemDrop().getEntityId() == 276 || event.getItemDrop().getEntityId() == 114){
            event.setCancelled(true);
            player.sendMessage(ChatColor.RED + "You Can't Drop This");
        }
    }
}

Thanks a lot! I just want to know why it's not working and how i can fix it.

 

Code:

@EventHandler
    public void ItemDrop(PlayerDropItemEvent event){
        Player player = event.getPlayer();
        if(event.getItemDrop().getEntityId() == 276 || event.getItemDrop().getEntityId() == 114){
            event.setCancelled(true);
            player.sendMessage(ChatColor.RED + "You Can't Drop This");
        }
    }

Add EventHandler above it
