InventoryClickEvent Help

Hey im having a problem with InventoryClickEvent.
I need it to Check if the player has click on a specific item.
This is my current code:

Code:java

package com.billcraftgaming.blitz;
 
import org.bukkit.Bukkit;
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.inventory.InventoryClickEvent;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.inventory.Inventory;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.PlayerInventory;
import org.bukkit.plugin.java.JavaPlugin;
 
public final class Blitz extends JavaPlugin implements Listener {
 
Inventory Blitz = Bukkit.createInventory(null, 9, "Blitz selection");
 
@Override
public void onEnable(){
getLogger().info("Enabled Blitz");
Bukkit.getServer().getPluginManager().registerEvents(this, this);
}
@Override
public void onDisable() {
getLogger().info("Disaled Blitz");
}
 
@EventHandler
public void onPlayerInteractBlock(PlayerInteractEvent event) {
Player player = event.getPlayer();
if (player.getItemInHand().getTypeId() == Material.NETHER_STAR.getId()) {
Blitz.setItem(0, new ItemStack(Material.DIAMOND_HELMET, 1));
Blitz.setItem(1, new ItemStack(Material.DIAMOND_SWORD, 1));
player.openInventory(Blitz);
}
}
 
public void onInventoryClick(InventoryClickEvent event) {
Player player = (Player) event.getWhoClicked();
PlayerInventory inventory = player.getInventory();
if (event.getInventory() == Blitz && event.getCursor() == new ItemStack(Material.DIAMOND_HELMET)); { //function 1
Bukkit.broadcastMessage("§a"+player.getName()+" has activated ###");
event.setCancelled(true);
player.closeInventory();
inventory.addItem(new ItemStack(Material.DIAMOND_HELMET));
inventory.addItem(new ItemStack(Material.DIAMOND_CHESTPLATE));
inventory.addItem(new ItemStack(Material.DIAMOND_LEGGINGS));
inventory.addItem(new ItemStack(Material.DIAMOND_BOOTS));
}
if (event.getInventory() == Blitz && event.getCursor() == new ItemStack(Material.DIAMOND_SWORD)); { //function 2
Bukkit.broadcastMessage("§a"+player.getName()+" has activated ###");
event.setCancelled(true);
player.closeInventory();
inventory.addItem(new ItemStack(Material.DIAMOND_SWORD));
}
}
 
} 

It puts the items in the Blitz inventory correctly but wont do the other functions.

Bump?

    }
  }
