how to check if there is a certain string in config.yml

Hello,
I am making a player-specific MOTD plugin, and I was wondering how to check if there is a string for that player in the config.yml file.
What my config.yml file looks like:

Code:

message: Welcome to the server!
 
users:
    lobuo: Custom MOTD!

And here is what my Main.java file looks like:

Code:java

package tk.lobuo.playermotd;
 
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.player.PlayerJoinEvent;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin implements Listener {
 
    @EventHandler
    public void onJoin(PlayerJoinEvent e) {
        Player p = e.getPlayer();
 
        String username = p.getName();
 
        if (/*Username is in MOTD file as "users.username"*/) { //Custom MOTD
            p.sendMessage(ChatColor.GOLD + getConfig().getString("users." + username /*Not sure if this will work*/ ));
        }
        else { //no custom MOTD
            p.sendMessage(ChatColor.GOLD + getConfig().getString("message"));
        }
    }
 
    public void onEnable() {
        Bukkit.getServer().getLogger().info(ChatColor.GREEN + "PlayerMOTD version 1.0 enabled!");
 
        getConfig().options().copyDefaults(true); //Creates config.yml if none with default values
        saveConfig();
        Bukkit.getServer().getPluginManager().registerEvents(this, this); //tells bukkit that this is a listener (and a plugin), so it knows to listen for players joining
    }
 
    public void onDisable() {
        Bukkit.getServer().getLogger().info(ChatColor.RED + "PlayerMOTD version 1.0 disabled!");
    }
 
    /* Unfinished commands
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
       
        if (cmd.getName().equalsIgnoreCase("motd")) {
           
        }
       
        return true;
       
    }
    */
 
}
 

 

lobuo

Code:java

for(String s:getConfig().getConfigurationSection("users").getKeys(false)){
    if(s.equals(PLAYER_NAME)){
        //The config contained the player name under the section users
        //Do stuff
    }
}

When I do that, it gives me a message that says null instead of my message that I set.
My code:

Code:java

package tk.lobuo.playermotd;
 
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.player.PlayerJoinEvent;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin implements Listener {
 
    @EventHandler
    public void onJoin(PlayerJoinEvent e) {
        Player p = e.getPlayer();
 
        String username = p.getName();
 
        for (String s:getConfig().getConfigurationSection("users").getKeys(false)){
            if (s.equals(username)){
            p.sendMessage(ChatColor.GOLD + getConfig().getString(username));
            }
        }
 
        /*if (configString != null) { //Custom MOTD
            p.sendMessage(ChatColor.GOLD + getConfig().getString(configString /*Not sure if this will work ));
        }
        else { //no custom MOTD
            p.sendMessage(ChatColor.GOLD + getConfig().getString("message"));
        } */
    }
 
    public void onEnable() {
        Bukkit.getServer().getLogger().info(ChatColor.GREEN + "PlayerMOTD version 1.0 enabled!");
 
        getConfig().options().copyDefaults(true); //Creates config.yml if none with default values
        saveConfig();
        Bukkit.getServer().getPluginManager().registerEvents(this, this); //tells bukkit that this is a listener (and a plugin), so it knows to listen for players joining
    }
 
    public void onDisable() {
        Bukkit.getServer().getLogger().info(ChatColor.RED + "PlayerMOTD version 1.0 disabled!");
    }
 
    /* Unfinished commands
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
       
        if (cmd.getName().equalsIgnoreCase("motd")) {
           
        }
       
        return true;
       
    }
    */
 
}
 

mydeblob Nevermind. I changed line 23 from p.sendMessage(ChatColor.GOLD + getConfig().getString(username)); to p.sendMessage(ChatColor.GOLD + getConfig().getString("users." + username)); Thanks!
