Solved NullPointerException Event

I'm having this strange issue of a NullPointerEvent. My event works perfect when the item is exactly what is specified. It's looking for a named item. But when I click on the item that ISN'T named, it gives me an NPE

Here's my listener class for a PlayerInteractEvent:

Code:

package me.choco.conditions.events;

import me.choco.conditions.Conditions;
import me.choco.conditions.particles.ParticleEffect;

import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.Action;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.inventory.ItemStack;

public class PlayerClickEvent implements Listener{
    @EventHandler
    public void onPlayerClick(PlayerInteractEvent event){
        if (event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() == Action.RIGHT_CLICK_BLOCK){
            if (event.getPlayer().getItemInHand().getType() == Material.PAPER && event.getPlayer().getItemInHand().getItemMeta().getDisplayName().equals(ChatColor.RED + "Bandage")){
                if (event.getPlayer().getHealth() <= 16){

                        Conditions.bleeding.remove(event.getPlayer().getName());
                        event.getPlayer().setHealth(event.getPlayer().getHealth() + 4);
                        event.getPlayer().sendMessage(ChatColor.DARK_RED + "Condition> " + ChatColor.GRAY + "The bandage patched you up! You have stopped bleeding");

@2008Choco The item in the player hand can be null. Not every item has an ItemMeta. Not every itemmeta has an DisplayName. Do null or "x.hasItemMeta()", "x.hasDisplayName()" checks.

 

Thank you @I Al Istannen Absolutely overlooked that. That's my bad
