Solved Config Variables Help

I'm fooling around with configs, and I'm trying to make variables for players so %PLAYER would be = to a players name. However, the way I set it up does not work.

Main:

Code:java

package com.config;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.event.player.PlayerQuitEvent;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin implements Listener {
 
    public static FileConfiguration config;
 
    public void onEnable() {
        Bukkit.getServer().getPluginManager().registerEvents(this, this);
        config = getConfig();
        try {
            saveConfig();
            setupConfig(getConfig());
            saveConfig();
        } catch(Exception e) {
            e.printStackTrace();
        }
    }
 
    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent e) {
        e.setJoinMessage(config.getString("Join"));
    }
 
    @EventHandler
    public void onPlayerQuit(PlayerQuitEvent e) {
        e.setQuitMessage(config.getString("Quit"));
    }
 
    public String formatVariables(String string, Player player) {
        return ChatColor.translateAlternateColorCodes("&".charAt(0), null)
          .replace("%PLAYER", player.getName());
      }
 
    private void setupConfig(FileConfiguration config) {
        config.set("Join", "&3[&bJoin&3] &9%PLAYER has arrived!");
        config.set("Quit", "&3[&bQuit&3] &9%PLAYER has left!");
    }
 
}

Any help is appreciated!

 

Code:java

//Use this to replace all %PLAYER to PlayerName
e.setJoinMessage(config.getString("Join").replaceAll("%PLAYER", p.getName().toString()));

 

Thanks!
