NullPointerException

Code:

// imports are cuted of
public class TargetDeath implements Listener {
   
    UUID uID = Main.plugin.uniqueID; // imports uniqueID of target
    public static TargetDeath api;

    boolean died = false; //just little boolean

    ItemStack[] tItems;   <<- here's the problem

   
    public TargetDeath() {

    if(tItems == null) {
        return;
    }
    }

    @EventHandler
    public void onEntityDeath(EntityDeathEvent e) {
        api = this;
       
        if((e.getEntity() instanceof Player)) {
           
            UUID eU = e.getEntity().getUniqueId();
            if((eU == uID)) {
               
                Player target = (Player) e.getEntity();
                Inventory tInv = target.getInventory();
                this.tItems = tInv.getContents();
                this.died = true;
            }
        }
    }

}

}

So as you can see there is ItemStack[] wich is getting items from target what died but when i turn it on in console will be : "NullPointerException" caused by this code, is possible to avoid it ? or i have to do it another way ?

btw sorry for broken english

 

like Main class ?

                zs[3] =    (Zombie) t.getLocation().getWorld().spawnEntity(t.getLocation(), EntityType.ZOMBIE);
               
                if(died == true) {
                   
                    tcInv.addItem(tItems);
                for(Zombie zombie : zs) {
                    zombie.setHealth(0);
                    player.openInventory(tcInv);
                   
                    }
                }
               
            }
        }
        return true;
    }
}

and console:
