Solved Getting players Inventory contents and adding them to a GUI?

So basically i am not sure how to get the players inventory contents and add them to a GUI for example.

Code:

  @EventHandler
    public void clicked(PlayerInteractEntityEvent e) {
        Player rightclick = (Player) e.getRightClicked();
        Player p = e.getPlayer();



        if(rightclick instanceof Player){
        
            
                ItemStack[] iv = rightclick.getInventory().getContents();
                Inventory rightCcon = Bukkit.createInventory(null, 54, "§a" + rightclick.getName() + "'s Inventory");
                p.sendMessage(pre + "§cYou have opened §7" + rightclick.getName() + "'s §cinventory.");
                rightCcon.addItem(iv);
                p.openInventory(rightCcon);

It works just fine please help! (On getting the player's item in hand).

 

Done. Please help.

 

First check, then cast.

 

Example code please.

 

Code:

for(ItemStack i : rightclick.getInventory().getContents()){

                Inventory rightCcon = Bukkit.createInventory(null, 54, "§a" + rightclick.getName() + "'s Inventory");
                p.sendMessage(pre + "§cYou have opened §7" + rightclick.getName() + "'s §cinventory.");
                rightCcon.addItem(i);
                p.openInventory(rightCcon);

Doesnt work timmy.

 

I was about to post how to do it without giving code, but then your post about that. Please be considerate when posting.
