Get items in chest and add to players inventory

What I'm trying to do is to, instead of opening a chest, give the player the items inside the chest, but also keep the items inside the chest, then I want to deny the player who opened the chest to open it again. So they can get the items, but they can't get it a 2nd time and it will display them a message telling them so.
Then another player can come along and do the same thing and get the same items.

Here is what I have:

Code:

    public void onChestOpen(PlayerInteractEvent event) {
        Player p = (Player) event.getPlayer();
        Block block = event.getClickedBlock();
        if(event.getAction().equals(Action.LEFT_CLICK_BLOCK) || event.getAction().equals(Action.RIGHT_CLICK_BLOCK) && block != null);
        {
            if(block.getState() instanceof Chest || block.getState() instanceof DoubleChest)
            {
                event.setCancelled(true);
                Chest chest = (Chest) block.getState();
                Inventory inv = chest.getBlockInventory();
                p.getInventory().addItem(inv); //atm I'm getting errors on this line, and not sure what I need to do.
               
            }

Thanks in advance.

Anyone got any idea??

event.setCancelled(true);
Chest chest = ((Chest) block.getState());
Inventory inv = chest.getBlockInventory();
p.getInventory().addItem(inv); //atm I'm getting errors on this line, and not sure what I need to do.

}

Just (() theese you had wrong. That one just cast the block but not gets it's state the double cast cast's everything inside of ()

 

I still get errors on addItem

 

You cannot add a hole inventory with addItem().
I think you have to get all Itemstacks, that are in inv and add them one by one to the players inventory.

 

Could I make a List or HashMap to do it?

 

Yes.

I would recommend a list.

 

Ok I will try that soon. Thanks

Ok, I got it working, here's how I did it:

Code:

Chest chest = ((Chest) block.getState());
ItemStack[] items = chest.getInventory().getContents();
p.getInventory().addItem(items);
p.updateInventory();
