List<String> lore = new ArrayList<String>();
        ItemStack ticket = new ItemStack(Material.PAPER);
        ItemMeta t = ticket.getItemMeta();
        t.setDisplayName(ChatColor.GREEN+"Lottery Ticket");
        lore.add(ChatColor.GRAY+"Iron");
        t.setLore(lore);
        ticket.setItemMeta(t);   
        ShapedRecipe sticket = new ShapedRecipe(ticket).shape(" D ", " R ", " S ").setIngredient('D', Material.IRON_INGOT).setIngredient('R', Material.REDSTONE).setIngredient('S', Material.STICK);
        getServer().addRecipe(sticket);

and i have the code:

Code:

                                                    if (player.getItemInHand().getType() == Material.PAPER)
                                                    {
                                                            if(player.getItemInHand().getItemMeta().getLore().equals(ChatColor.AQUA+"Diamond")
                                                                    {
 
                                                                j.add(player.getName());
                                                                int i = player.getItemInHand().getAmount();
                                                                ItemStack n = new ItemStack(Material.PAPER, i - 1);
                                                                player.setItemInHand(n);
                                                                player.sendMessage(ChatColor.GREEN + "You have joined the lottery!");
                                                           
                                                        {
                                               
                                                        else
                                                        {
                                                                player.sendMessage(ChatColor.RED + "You must put ticket in your hand");
                                                        }
{

You can fix it for me? thank you!

 

The .getLore() method will return a List<String>, and you are assuming it is returning a single string. Use player.getItemInHand().getItemMeta().getLore().contains(ChatColor.AQUA + "Diamond").

 

Its work but i have more error with this code

Code:

if(player.getItemInHand().getItemMeta().getLore().contains(ChatColor.GRAY+"Iron"))
                                                        {
                                                   
                                                                j.add(player.getName());
                                                                int i = player.getItemInHand().getAmount();
                                                                ItemStack n = new ItemStack(Material.PAPER, i - 1);
                                                                player.setItemInHand(n);
                                                                player.sendMessage(ChatColor.GREEN + "You have joined the lottery!");
                                                        }
                                                        

If the player do the command with a regular paper have this error:
"An interal error occurred while attempting to perfrom this command"
