Scoreboard API problems

Not sure what can possibly be wrong here, all I did was declare an Objective object and returned myself an Objective from the scoreboard's method. And now whenever I try to apply a method to the Objective I'm thrown with errors.

On a side note: Anyone know what the first string argumenent for the registerNewObjective method is for?

Code:

import org.bukkit.Bukkit;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.ScoreboardManager;
 
public class ScoreBoardManager {
 
ScoreboardManager manager = Bukkit.getScoreboardManager();
 
Scoreboard board = manager.getNewScoreboard();
                                      //Not sure what the first argument here means
Objective dollars = board.registerNewObjective("test?", "dummy");
//dollars can be resolved as anything, despite the variable right above me
dollars.setDisplaySlot(DisplaySlot.BELOW_NAME);

 

Creeoer The register new objective is
registerNewObjective("<Custom objective name>", "<Type of objective like "dummy">")

Thanks for the method insight for the first argument, but that doesn't solve my problem with the fact that dollars isn't being resolved as anything..

That's not how the syntax works. You need to execute methods of an object in a method or constructor.

Thanks, never put it in a constructor.
