Why doesn't this code write on the background on the screen?

I'm trying to display the best player name and time, so the player that has the lowest score and wrote this: 
import greenfoot.*;
import java.io.*;
import java.util.ArrayList;

public class ArcScoreBoard extends Menu
{

    ArrayList<String> lines = new ArrayList<String>();
    
    public ArcScoreBoard()
    {
        
        GreenfootImage background1;
        Font font1 = new Font("Defaut1", false, false, 24);
        background1 = getBackground();
       
        background1.setFont(font1);
        
        background1.setColor(Color.BLACK);
        
        try
        {
                    
            FileReader fr = new FileReader("ArcadeScores.txt");
            BufferedReader br = new BufferedReader(fr);
            //String line = br.readLine();
            
            String line = null; // sets up a local field for each line of text
            while ((line = br.readLine()) != null)  lines.add(line); // read each line and add them to the 'lines' list
            for(int i = 0; i < lines.size(); i++)
            {
                
                String[] firstPlace  = null;
                
                String[] fullLine = lines.get(i).toString().split(";");
                int score = Integer.parseInt(fullLine[0]);
                                    
                if(firstPlace == null && score == i)
                {
                
                    firstPlace = fullLine;
                   background1 .drawString("1." + firstPlace[1] + firstPlace[2], 50, 50);
                    
                }

            }
            
        }
        catch(IOException e)
        {
            
            System.err.println("Caught IOException: " + e.getMessage());
            
        }
        
        
        
    }
and also tried this: 
import greenfoot.*;
import java.io.*;
import java.util.ArrayList;

public class ArcScoreBoard extends Menu
{

    ArrayList<String> lines = new ArrayList<String>();
    
    public ArcScoreBoard()
    {
        
        GreenfootImage background1;
        Font font1 = new Font("Defaut1", false, false, 24);
        background1 = getBackground();
       
        background1.setFont(font1);
        
        background1.setColor(Color.BLACK);
  
    }
    
    public void act(){
        
        try
        {
                    
            FileReader fr = new FileReader("ArcadeScores.txt");
            BufferedReader br = new BufferedReader(fr);
            //String line = br.readLine();
            
                            
            String[] firstPlace  = null;
            
            String line = null; // sets up a local field for each line of text
            while ((line = br.readLine()) != null)  lines.add(line); // read each line and add them to the 'lines' list
            for(int i = 0; i < lines.size(); i++)
            {

                String[] fullLine = lines.get(i).toString().split(";");
                int score = Integer.parseInt(fullLine[0]);
                                    
                if(firstPlace == null && score == i)
                {
                
                    firstPlace = fullLine;
                    getBackground().drawString("1." + firstPlace[1] + firstPlace[2], 50, 50);
                    
                }

            }
            
        }
        catch(IOException e)
        {
            
            System.err.println("Caught IOException: " + e.getMessage());
            
        }
}
    
}
And in the ArcadeScores.txt file there's this: 
824;Player1;00:00:03.82
236;Player2;00:00:01.56
654;Player3;00:02:03:36
686;Player4;00:64:65.00
986;Player5;00:05:23.65
355;Player6;00:00:51.67
that I randomly added manually Can anyone help me make this work please?

So... I know it's not very professional, but the Menu class is empty, I just used it to sort the subclasses of the Title Screen class here: 
import greenfoot.*;

public class TitleScreen extends World
{

    //MUSIC
    public static GreenfootSound bgMusic;
    
    /**
     * Constructor for objects of class TitleScreen.
     * 
     */
    public TitleScreen()
    {    
        
        super(Game.WIDE, Game.HIGH, Game.CELL, false);
        addObject(new Reference(), -50, -50);
        
    }    
    
    /**
     * Act - do whatever the Class wants to do. This method is called whenever
     * the 'Act' or 'Run' button gets pressed in the environment.
     */
    public void act()
    {
        
        if(!this.getObjects(Reference.class).isEmpty()){
        
            if(bgMusic == null) //Play music when the a new world of class TitleScreen is set and bgMusic isn't defined yet
            {
            
                bgMusic= new GreenfootSound("soundtrackCM12.wav");
                bgMusic.setVolume(50);
                bgMusic.playLoop();
                
            } else {
            
                bgMusic.playLoop();
            
            }
            
        }
    
    }
    
    /**
     * This method is called by the Greenfoot system when the execution has started.
     */
    public void started()
    {
           
        if(bgMusic == null) //Play music when the a new world of class TitleScreen is set and bgMusic isn't defined yet
        {
        
            bgMusic= new GreenfootSound("soundtrackCM12.wav");
            bgMusic.setVolume(50);
            bgMusic.playLoop();
            
        }
    
    }
    
    /**
     * Forces the game to play the music if the bgMusic hasn't been set yet
     */
    public void playMusic()
    {
    
        if(bgMusic == null)
        {
        
            bgMusic= new GreenfootSound("soundtrackCM12.wav");
            bgMusic.setVolume(50);
            bgMusic.playLoop();
            
        }
    
    }
    
    /**
     * Stop music from playing
     */
    public void stopMusic()
    {
        
        bgMusic.stop();
        
    }
    
    /**

     */
    public void startArcade()
    {
    
        Greenfoot.setWorld(new ArcadeWorld());
        stopMusic();
    
    }
    
    /**
     * Starts Classic mode game
     */
    public void startClassic()
    {
    
        Greenfoot.setWorld(new ClassicWorld());
        stopMusic();
    
    }
    
    /**
     * Opens a new "Help" screen
     */
    public void help()
    {
    
        //Greenfoot.setWorld(new HelpScreen());
    
    }
    
    /**
     * Replays startitng animation
     */
    public void restartAnim() 
    {
    
        Greenfoot.setWorld(new A_StaticBeginning());
    
    }
    
    /**
     * Opens a new Score Board screen
     */
    public void openScoreBoard()
    {
    
        Greenfoot.setWorld(new ArcScoreBoard());
    
    }
    
    /**
     * Opens a new Selection Screen
     */
    public void backToMainMenu()
    {
    
        Greenfoot.setWorld(new SelectionScreen());
    
    }
    
}
There's also an act method here but if I understood correctly, if a subclass has an act method the main class' act is ignored right?

Here it is: 
import greenfoot.*;

public class Menu extends TitleScreen
{
/**
     * Constructor for objects of class Menu.
     * 
     */
    public Menu()
    {    
        
        
        
    }
   
}

Found a solution, turns out I'm just dumb: 
import greenfoot.*;
import java.io.*;
import java.util.List;
import java.util.ArrayList;

public class ArcScoreBoard extends Menu
{

    ArrayList<String> lines = new ArrayList<String>();
    ArrayList<String> topPl = new ArrayList<String>();
    
public ArcScoreBoard()
    {
        
        GreenfootImage background1 = new GreenfootImage("backgroundSB.jpg");
        Font font1 = new Font("Dialogue", false, false, 40);
       
        background1.setFont(font1);
        
        background1.setColor(Color.BLACK);
        
        setBackground(background1);
        
        background1.drawString("BEST ARCADE MODE PLAYERS", 50, 50);
        background1.drawString("Player Name: ", 50, 150);
        background1.drawString("Time: ", Game.WIDE/2, 150);
        
        String[] top         = null;

                    }
                        
                }

                //System.out.println(max);

            }
