Solved getDisplayName() error

Plugin is working fine but sometimes write this error in console

And this is my 83 Line in Events:

Code:

package me.bronzzze.wardrobe;



import org.bukkit.ChatColor;
import org.bukkit.Color;
import org.bukkit.GameMode;
import org.bukkit.Material;
import org.bukkit.Sound;
import org.bukkit.enchantments.Enchantment;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.Action;
import org.bukkit.event.inventory.InventoryClickEvent;
import org.bukkit.event.inventory.InventoryType.SlotType;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;
import org.bukkit.inventory.meta.LeatherArmorMeta;

public class Events implements Listener{
   
   
    private final Main main;
   



    public Events(Main main) {
        this.main = main;
        // TODO Auto-generated constructor stub
    }















    ArmourGUI i = ArmourGUI.getInstance();
    HatGUI i2 = HatGUI.getInstance();
    MainGUI i3 = MainGUI.getInstance();
   


    @EventHandler
    public void onClick(InventoryClickEvent e) {
        final Player p = (Player) e.getWhoClicked();
       

       
   
    if(e.getSlotType() == SlotType.ARMOR) {
        if(!(e.getWhoClicked().getGameMode() == GameMode.CREATIVE || e.getWhoClicked().isOp()))
        e.setCancelled(true);
    }
        if (e.getInventory()
                .getName()
                .equalsIgnoreCase("" + ChatColor.DARK_PURPLE + ChatColor.BOLD +  "Main Menu")) {
            if (e.getCurrentItem() == null) {
                return;
               
            }
            e.setCancelled(true);
            if (e.getCurrentItem().getType() == Material.LEATHER_CHESTPLATE) {
                p.closeInventory();
                i.openInventory(p);
               
               
            }
           
            if (e.getCurrentItem()
                    .getItemMeta()
                    .getDisplayName()
                    .contains("" + ChatColor.GOLD + ChatColor.BOLD
                            + "Hat Selector")) {
                p.closeInventory();
                i2.openInventory(p);

 

Check the following before continuing...

Code:

e.getCurrentItem().hasItemMeta()
e.getCurrentItem().getItemMeta().hasDisplayName()

 

Also getCurrentItem might return null :3

Ok when i click outside inventory i get this error

Superoriginal do you mean this?

Code:

                return;

Nvm now its working ty all.

i forgot to add

@bronzzze still want me and SupperOriginal are trying to say is that if the clicked item is nothing then you will get this error.... Also if you click out of da inv you'll get it... So, pay some effort and see when something turns to null, what hAppends in java, it will only take few minutes to read or watch a tutorial explaining it. There are plenty out there.
