1.15.2 api access to specific scoreboards

I've been attempting to get this blasted code to check a players scoreboard objective value and I cant get anything working and google is the worst for help.

Does anyone know where I can find/read an example for how to check specific scoreboard objectives?

 

when player runs a command, it checks players scoreboard objective "SP1", if SP1 = 1 then it triggers item give

 

getscoreboard cannot be resolved or is not a field

 

I have them imported,

Code (Java):

package itsa.me.mario;

import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scoreboard.Objective;


public class Test extends JavaPlugin {
    @Override
    public void onEnable() {
    }
    // Fired when plugin is disabled
    @Override
    public void onDisable() {
    }
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (cmd.getName().equalsIgnoreCase("objtest")) {
            Player p = Bukkit.getPlayer(sender.getName());
            @Nullable Objective sp1 = ((Player) sender).getScoreboard().getObjective("SP1");
            Objective score = sp1;
            p.sendMessage("Your Test Number: " + sp1);
        }
        return false;
    }
}

returns in game:

Code (Text):

Your Test Number: [email protected]28

 

That it doesnt show the score in chatbar... it shows the org.bukkit.xxxxxxx. Should be showing a number, not that

 

I cannot seem to get anything to stick and work, I've checked the docs and still get errors

 

This is where I am:

Code (Java):

import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Scoreboard;

public class Test extends JavaPlugin {
    @Override
    public void onEnable() {
    }
    // Fired when plugin is disabled
    @Override
    public void onDisable() {
    }
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (cmd.getName().equalsIgnoreCase("objtest")) {
            Player p = Bukkit.getPlayer(sender.getName());
            Scoreboard obj1 = p.Objective.getScores("SP1");
            p.sendMessage("Your SP1 score:" + obj1);      
        }
        return false;
    }
}

I am stuck on p.Objective.getScores, as "Objectives" is throwing: "Objective cannot be resolved or is not a field"
