Solved Going from one GUI to another

So im making a shop which is already said in my previous thread, and in it all I got is the menu. I wanna make it so that when you click an item it goes to a new GUI. I have part of what I want done at the end (Its the last chunk of code, starts with @Event handler)).

Code:

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.inventory.InventoryClickEvent;
import org.bukkit.inventory.Inventory;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;
import org.bukkit.plugin.java.JavaPlugin;

public class OpenShop extends JavaPlugin
{
public boolean onCommand(CommandSender theSender, Command cmd, String commandLabel, String[] args)
{
    if(commandLabel.equalsIgnoreCase("shop"))
    {
        Player player = (Player) theSender;
        {
        private void openGUI (Player player)
        {
            Inventory inv = Bukkit.createInventory(null, 18, ChatColor.GOLD + "Shop");
          
            ItemStack ores = new ItemStack(Material.IRON_INGOT);
            ItemMeta oresMeta = ores.getItemMeta();
            ItemStack raw_blocks = new ItemStack (Material.STONE);
            ItemMeta raw_blocksMeta = raw_blocks.getItemMeta();
            ItemStack crafted_blocks = new ItemStack (Material.SMOOTH_BRICK);
            ItemMeta crafted_blocksMeta = crafted_blocks.getItemMeta();
            ItemStack wood_and_plants = new ItemStack(Material.SAPLING);
            ItemMeta wood_and_plantsMeta = wood_and_plants.getItemMeta();
            ItemStack food_and_farming = new ItemStack (Material.GRILLED_PORK);
            ItemMeta food_and_farmingMeta = wood_and_plants.getItemMeta();
            ItemStack drops = new ItemStack (Material.SULPHUR);
            ItemMeta dropsMeta = drops.getItemMeta();
            ItemStack decorative = new ItemStack (Material.BOOKSHELF);
            ItemMeta decorativeMeta = decorative.getItemMeta();
            ItemStack mechanisms = new ItemStack(Material.REDSTONE_LAMP_ON);
            ItemMeta mechanismsMeta = mechanisms.getItemMeta();
            ItemStack misk = new ItemStack(Material.SADDLE);
            ItemMeta miskMeta = misk.getItemMeta();
            ItemStack dyes = new ItemStack (Material.YELLOW_FLOWER);
            ItemMeta dyesMeta = dyes.getItemMeta();
            ItemStack tools_and_combat = new ItemStack (Material.IRON_PICKAXE);
            ItemMeta tools_and_combatMeta = tools_and_combat.getItemMeta();
            ItemStack brewing = new ItemStack (Material.BREWING_STAND);
            ItemMeta brewingMeta = brewing.getItemMeta();
            ItemStack enchanting = new ItemStack (Material.ENCHANTED_BOOK);
            ItemMeta enchantingMeta = enchanting.getItemMeta();
          
            oresMeta.setDisplayName(ChatColor.GRAY + "Ores");
            ores.setItemMeta(oresMeta);

            food_and_farming.setItemMeta(food_and_farmingMeta);

            misk.setItemMeta(miskMeta);
          
            dyesMeta.setDisplayName (ChatColor.BLUE + "D" + ChatColor.GREEN + "y" + ChatColor.YELLOW + "e" + ChatColor.DARK_RED + "s");

            enchanting.setItemMeta (enchantingMeta);
          
            inv.setItem(2, ores);
            inv.setItem(3, raw_blocks);
            inv.setItem(4, crafted_blocks);
            inv.setItem(5, food_and_farming);
            inv.setItem(6, wood_and_plants);
            inv.setItem(7, drops);
            inv.setItem(8, decorative);
            inv.setItem(11, mechanisms);
            inv.setItem(12, misk);
            inv.setItem(13, dyes);
            inv.setItem(15, tools_and_combat);
            inv.setItem(16, brewing);
            inv.setItem(17, enchanting);
          
            player.openInventory(inv);
          
        }
        @EventHandler
        public void onInventoryClick(InventoryClickEvent event) {
            if (!ChatColor.stripColor(event.getInventory().getName())
                    .equalsIgnoreCase("Shop"))
                if (getClickedItem.equalsIgnoreCase("Ores"));
                  
              
        }
        }
    }
return true;
}
}
      

 

First, remove the semicolon. This means this if statement does nothing.

Second: You cannot have methods inside of other methods. Move the event out of the onCommand.

Finally: You never state what is currently happening and what is not working.

 

First, im a finicky writer. I write and then proof read/fix my mistakes.

Second: thanks, didnt know that.

Third: Nothings necessarily wrong, I just want to know how to continue to a new GUI

Actually, nvm. I figured it out
