Solved Issues with static referencing

I have the code below in my listener class and am trying to use the method in the class MainClass called logUUID(). But, I get an error on the line that is MainClass.logUUID(player); stating that it Cannot make a static reference to the non-static method logUUID(Player) from the type MainClass. Any ideas why, I'm totally confused here.

Code:

package com.georlegacy.general.betterwarnings;

import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;

public class JoinListener implements Listener {
   
    @EventHandler
    public void playerJoinEvent(PlayerJoinEvent e) {
        Player player = e.getPlayer();
        MainClass.logUUID(player);
    }
}

Code:

    //method to log player uuid to config file
    public void logUUID(Player player) {
        String pname = player.getName();
        UUID puuid = player.getUniqueId();
        String path = "UUIDs." + pname.toLowerCase();
        getLogger().info("INFO: Player " + pname + " joined with UUID " + puuid + "!");
        if (!(getConfig().contains(path))) {
            getLogger().info("INFO: " + pname + " is joining for first time! Logging UUID to config file!");
            getConfig().set(path, puuid);
        }
    }

 

So I just have to put in a line that says MainClass MainClass;?

 

Changed to lowercase variable, what did you mean by fill it using the constructor?

 

So do I need to add more code than this:

Code:

package com.georlegacy.general.betterwarnings;

import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;

public class JoinListener implements Listener {
   
    MainClass mainClass;
   
    @EventHandler
    public void playerJoinEvent(PlayerJoinEvent e) {
        Player player = e.getPlayer();
        mainClass.logUUID(player);
    }
}

 

How do I add a constructor?

 

Any chance you could tell me how I would do it in my case?

 

Ok thanks for your help so far though marking as solved.
