Scoreboard API

Hello, recently I completed my MySQL token system and have advanced onto a much simpler plugin that would display a player's token balance using the Token API (that I created) and the Bukkit Scoreboard API. Would it go something like this?

Code:

package me.fightordie.boltsoft.coins.bar;
 
import me.fightordie.boltsoft.coins.CoinMethods;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
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;
import org.bukkit.scoreboard.DisplaySlot;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Score;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.ScoreboardManager;
 
public class Main extends JavaPlugin implements Listener {
   
    public void updateScoreboard(Player player) {
       
    ScoreboardManager manager = Bukkit.getScoreboardManager();
    Scoreboard board = manager.getNewScoreboard();
    Objective obj = board.registerNewObjective("stats", "dummy");
    obj.setDisplaySlot(DisplaySlot.SIDEBAR);
    obj.setDisplayName("" + ChatColor.YELLOW + "[BC]");
   
    Score pMoney = obj.getScore(CoinMethods.getPlayer(String));;
    }
   
    @EventHandler
        public void onPlayerJoin(PlayerJoinEvent e) {
        updateScoreboard(e.getPlayer());
    }
   
    @Override
        public void onEnable() {
            Bukkit.getPluginManager().registerEvents(this, this);
    }
   
   
 
}

How my Token API connects to the database and retrieves information: (for a /coins list command):

Code:

CoinMethods.getTPlayer(p, args[1]);

and

Code:

 conn = DriverManager.getConnection(javaURL);
      Class.forName("com.mysql.jdbc.Driver");
      Statement stmt = conn.createStatement();
      ResultSet rp1 = stmt.executeQuery(query);
      if (rp1.next()) {
        Bukkit.getServer().getPlayer(name).sendMessage(ChatColor.YELLOW + "[BC] " + ChatColor.GREEN + "You have " + ChatColor.BOLD + rp1.getInt("money") + ChatColor.GREEN + " coins");

Thanks!

Mainly concerned on presenting the Money field on the sidebar.
