Accessing variables and config from other classes

As the titles says, I'm having trouble accessing the config file and variables from other files.

I've looked on many threads, but I can't seem to get it to work.

Here's my code

main:

Code:

public class Multitool extends JavaPlugin implements Listener {
   
    private static Plugin plugin;
   
    public void onEnable() {///////////////////////////////////////////////////////////////////////////////////////////////Enable Disable
        getServer().getPluginManager().registerEvents(this, this);
        plugin = this;
        getCommand("multitool").setExecutor(this);
        System.out.println("Darkolythe Multitool enabled!");
    }
   
    public void onDisable() {
        plugin = null;
        System.out.println("Darkolythe Multitool disabled!");
    }
   
    //register  events in all classes instead of one at a time
    public static void registerEvents(org.bukkit.plugin.Plugin plugin, Listener... listeners) {
        for (Listener listener : listeners) {
            Bukkit.getServer().getPluginManager().registerEvents(listener,  plugin);
        }
    }
   
    //Access the plugin from other classes
    public static Plugin getPlugin() {
        return plugin;
    }

SaveLoadInventory:

Code:

package me.Darkolythe.Multitool;

import java.util.HashMap;
import java.util.UUID;
import java.util.Map.Entry;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;

import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.inventory.InventoryType;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.event.player.PlayerQuitEvent;
import org.bukkit.inventory.Inventory;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.java.JavaPlugin;

public class SaveLoadInventory implements Listener {
   
   
   
    private HashMap<UUID, Inventory> toolinv = new HashMap<UUID, Inventory>();
       
   
   
    public void onEnable() {///////////////////////////////////////////////////////////////////////////////////////////////Enable Disable
        getServer().getPluginManager().registerEvents(this, this);
    }
   
    public void onDisable() {
       
        for (Entry<UUID, Inventory> entry : toolinv.entrySet()) {
            if (!getConfig().contains("toolinv." + entry.getKey())) {
                getConfig().createSection("toolinv." + entry.getKey());
            }
            char c = 'a';
            for (ItemStack itemstack : entry.getValue()) {
                if (itemstack != null) {
                    saveItem(getConfig().createSection("toolinv." + entry.getKey() + "." + c++), itemstack);
                }
            }
            saveConfig();
        }
    }

   
   
    @EventHandler//////////////////////////////////////////////////////////////////////////////////////////////////////////Player leave and join
    public void onPlayerJoin(PlayerJoinEvent event) {
       
        Inventory inv = Bukkit.getServer().createInventory(event.getPlayer(), InventoryType.HOPPER, "Multitools");
       
        if (getConfig().contains("toolinv." + event.getPlayer().getUniqueId())) {
            for (String item : getConfig().getConfigurationSection("toolinv." + event.getPlayer().getUniqueId()).getKeys(false)) {
                inv.addItem(loadItem(getConfig().getConfigurationSection("toolinv." + event.getPlayer().getUniqueId() + "." + item)));
            }
        }
        toolinv.put(event.getPlayer().getUniqueId(), inv);
    }
   
    @EventHandler
    public void onPlayerLeave(PlayerQuitEvent event) {
       
        if (!getConfig().contains("toolinv." + event.getPlayer().getUniqueId())) {
            getConfig().createSection("toolinv." + event.getPlayer().getUniqueId());
        }
       
        getConfig().set("toolinv." + event.getPlayer().getUniqueId(), null);
       
        char c = 'a';
        for (ItemStack itemstack : toolinv.get(event.getPlayer().getUniqueId())) {
            if (itemstack != null) {
                saveItem(getConfig().createSection("toolinv." + event.getPlayer().getUniqueId() + "." + c++), itemstack);
            }
        }
        saveConfig();
    }
   
   
   
    private void saveItem(ConfigurationSection section, ItemStack itemstack) {/////////////////////////////////////////////Save Load Inv
        section.set("itemstack", itemstack);
    }
   
    private ItemStack loadItem(ConfigurationSection section) {
        ItemStack itemstack = new ItemStack(section.getItemStack("itemstack"));
       
        return itemstack;
    }
   
}

command file: ( I want to give toolinv to SaveLoadInventory and command file)

Code:

public class MultitoolCommand implements CommandExecutor {

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String commandlabel, String[] args) {
        if (!(sender instanceof Player)) {
            sender.sendMessage(ChatColor.RED + "The console cannot use a multitool!");
        }
       
        Player player = (Player) sender;
        if (player.hasPermission("Multitool.command")) {
            if (cmd.getName().equalsIgnoreCase("Multitool")) {
                if (args.length == 1) {
                    if (args[0].equalsIgnoreCase("Open")) {
                        player.openInventory(toolinv.get(player.getUniqueId()));
                    } else if (args[1].equalsIgnoreCase("toggle")) {
                       
                    } else {
                        sender.sendMessage(ChatColor.RED + "Invalid Arguments: Toggle, Open");
                    }
                } else {
                    sender.sendMessage(ChatColor.RED + "Invalid Arguments: Toggle, Open");
                }
            }
        }
        return true;
    }
   
}

 

@thechrisanator Maybe something like this would work.
SaveLoadInventory class:

Code:Java

public HashMap<UUID, Inventory> getToolInv() {
    return toolinv;
}

Main class:

Code:Java

private SaveLoadInventory saveloadinventory;
 
public void onEnable() {
    saveloadinventory = new SaveLoadInventory();
}
 
public SaveLoadInventory getSaveLoadInventory() {
    return saveloadinventory;
}

Command class:

Code:Java

private HashMap<UUID, Inventory> toolinv = Multitool.getPlugin().getSaveLoadInventory().getToolInv();

@thechrisanator Try changing the type of getPlugin in your main class from 'Plugin' to 'Multitool'
