I have to been working on a plugin for a couple of days or so now and I'm not sure on how to do this. I have a command /punish which opens an inventory where moderators can mute, kick, ban or warn the player in arg[0]. once the command has opened the first inventory, I made a different class called guievents which controls the inventory. My question is, how do I get the args from the command in one class to another class. I've been searching on google for a while and most of the time I found people using hashmaps, however, I never quite understood how they were doing it, or if I should use hashmaps at all.
Command Class:

package io.github.bxnie.gui.punish;



import java.util.ArrayList;



import org.bukkit.Bukkit;

import org.bukkit.ChatColor;

import org.bukkit.inventory.ItemFlag;

import org.bukkit.inventory.ItemStack;

import org.bukkit.inventory.meta.ItemMeta;



import net.minecraft.server.v1_12_R1.CommandExecute;



public class punish extends CommandExecute implements Listener, CommandExecutor{



    public String punish = "punish";



    //open main GUI for moderation /punish

    public boolean onCommand(CommandSender sender, Command cmd, String label, String args) {

        Player p = (Player) sender;

        if (!(sender instanceof Player)) {

            sender.sendMessage("Only players may execute this command!");

            return true;

        }

        if (cmd.getName().equalsIgnoreCase(punish) && sender instanceof Player) {

            if (p.hasPermission("fp.punish")) {

                if (args.length == 0){

                    p.sendMessage(ChatColor.DARK_GRAY + "[" + ChatColor.DARK_RED + ChatColor.BOLD + "Fiore" + ChatColor.DARK_GRAY + "] " + ChatColor.RED + "Correct usage: " + ChatColor.GRAY + ChatColor.ITALIC + "/punish <player>");

                    return false;

                }

                if (args.length >= 1){

                    String message = "";

                    Player target = Bukkit.getPlayer(args[0]);

                    for (int i = 0; i < args.length; i++) {

                        message = message + args[i] + " ";

    }

}

in the second screenshot, I put a temporary "name" as a placeholder as i dont know what to put. if anyone is to reply, could you like explain what you are doing just so i dont fall short of this again.
Thanks

You could use HashMaps,

What you should do is make a HashMap in your CommandClass.

Make the Player object the Key and the arg(s) the value like this:
HashMap myHashMap - In case of a single argument.

HashMap myHashMap - In case of multiple arguments.

Then each time before you open the GUI you should put the Player and Arg(s) in the HashMap. You should implement methods in your command class for fetching the values, for example, public String getArg(Player player), and return the value. And also a remove method(This will prevent errors) called, public void removeArgs(Player player), this should be called when the GUI is closed or whenever you like it.

Hope you could find any use in this.
