Generating Stuff Inside Configs

How would you generate stuff in a config? Even if its a custom config...

Main:

Code:

package com.config;
 
import java.io.File;
import java.io.IOException;
import java.util.logging.Logger;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.configuration.file.YamlConfiguration;
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 final Logger logger = Logger.getLogger("Minecraft");
 
    File messages;
    FileConfiguration messageConf;
   
    public void onEnable(){
        Bukkit.getServer().getPluginManager().registerEvents(this, this);
        messages = new File(getDataFolder(), "messages.yml");
        messageConf = YamlConfiguration.loadConfiguration(messages);
        saveConf();
        try {
            saveConf();
            setupConfig(messageConf);
            saveConf();
        } catch(Exception e) {
            e.printStackTrace();
        }
    }
   
    public void saveConf(){
        try{
            messageConf.save(messages);
   
        }catch(Exception e){
            e.printStackTrace();
        }
    }
    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent e) {
        e.setJoinMessage(ChatColor.translateAlternateColorCodes(
                "&".charAt(0), messageConf.getString("Join").replaceAll("%PLAYER",
                        e.getPlayer().getName().toString())));
    }
 
    @EventHandler
    public void onPlayerQuit(PlayerQuitEvent e) {
        e.setQuitMessage(ChatColor.translateAlternateColorCodes(
                "&".charAt(0), messageConf.getString("Quit").replaceAll("%PLAYER",
                        e.getPlayer().getName().toString())));
    }
   
    private void setupConfig(FileConfiguration config) throws IOException {
        if(!new File(getDataFolder(), "messages.yml").exists()) {
            new File(getDataFolder(), "messages.yml").createNewFile();
            messageConf.set("Join", "&3[&bJoin&3] &9%PLAYER has arrived!");
            messageConf.set("Quit", "&3[&bQuit&3] &9%PLAYER has left!");
            }
        }
   
}

I've tried the "setupConfig()" thing, but it doesn't work.

 

Try:

Code:

File file = new File(getDataFolder() + "/myfile.yml");
if(!file.exists){
    file.createNewFile();
}
 
FileConfiguration fileConfig = YamlConfiguration.loadConfiguration(file);
fileConfig.set("path", value);
 
try{
    fileConfig.save(file);
}catch(IOException e){
    e.printStackTrace();
}

 

@TheMcScavanger Ok, I got the config to set it.. However, when I try to set it to something else in the config, it always gets set back to its default state. (EX: Gens "Joined" and I put "Join" And when I reload it, it sets it back to "Joined") Any way to fix this?

Code:java

File messages = null;
    FileConfiguration messageConf = null;
 
    public void onEnable(){
        Bukkit.getServer().getPluginManager().registerEvents(this, this);
        this.messages = new File(getDataFolder(), "messages.yml");
        this.messageConf = YamlConfiguration.loadConfiguration(this.messages);
        this.messageConf.options().copyDefaults(true);
        messageConf.set("Join", "&3[&bJoin&3] &9%PLAYER has arrived!");
        messageConf.set("Quit", "&3[&bQuit&3] &9%PLAYER has left!");
        saveConf();
    }
