class variable not updating after method call

I am quite new to Java and only after researching and googling and reading many answers, I am posting this. I am kinda lost. A little guidance would be of great help. The following is a method from a class that implements the "ActionListener" interface. What I am trying to do is this: There is a button which one clicked should open a new window with two options in the form of two Radio Buttons. I need to know the Radio Button which was selected for further use in my code. I declared, the "scoreOption" variable as a class variable and static, and then attempt to update it in the "actionPerformed" abstract method. But when I refer to it (after the method call), the value stays the same - null, or whatever I set it to initially. Here is the code:

import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import java.io.FileNotFoundException;
import java.text.ParseException;
import java.util.ArrayList;
import java.util.Scanner;
import javax.swing.ButtonGroup;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.JTextArea;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;

public class StartEvents implements ActionListener {
    StartPanel startingPanel;
    static String scoreOption;
    
    public StartEvents(StartPanel startPanel) {
        startingPanel = startPanel;
    }
    // Scoring System Window - 1
    public void scoringSystem() {
        startingPanel.scoringSystem.addActionListener(new ActionListener () {
            @Override
            public void actionPerformed(ActionEvent e) {
                Panel scoringSystemPanel = new Panel();
                JFrame scoreSystemFrame  = scoringSystemPanel.frame(150, 250, "Scoring System", 2, true);
                JPanel scoreSystemPanel = scoringSystemPanel.panel(Color.lightGray);
                JButton confirmSelection = scoringSystemPanel.button(40, 20, "Confirm");
                JRadioButton scoreSystem1 = scoringSystemPanel.radioButton("Option 1: Same Points Per Hit");    
                scoreSystem1.setActionCommand("Option 1");
                JRadioButton scoreSystem2 = scoringSystemPanel.radioButton("Option 2: Unique Points Per Hit");
                scoreSystem2.setActionCommand("Option 2");
                ButtonGroup scoreSys = new ButtonGroup();
                scoreSys.add(scoreSystem1);
                scoreSys.add(scoreSystem2);
                scoreSystemFrame.getContentPane().add(scoreSystemPanel);
                scoreSystemPanel.add(scoreSystem1);
                scoreSystemPanel.add(scoreSystem2);
                scoreSystemPanel.add(confirmSelection);
                
                // Get Selection Event
                // Option 1
                scoreSystem1.addActionListener(new ActionListener () {
                    @Override
                    public void actionPerformed(ActionEvent e) {
                        if (scoreSystem1.isSelected()) {
                            scoreOption = scoreSystem1.getActionCommand();
                        }
                    }
                });
                // Option 2
                scoreSystem2.addActionListener(new ActionListener () {
                    @Override
                    public void actionPerformed(ActionEvent e) {
                        if (scoreSystem2.isSelected()) {
                            scoreOption = scoreSystem2.getActionCommand();
                        }
                    }
                });
                // Confirm Event 
                confirmSelection.addActionListener(new ActionListener() {
                    @Override
                    public void actionPerformed(ActionEvent e) {
                        scoreSystemFrame.dispose();
                    }
                });
            }
        });
    }

Main Game Class where the method scoringsystem is called.

import java.util.ArrayList;

public class Game {

    public static void main(String[] args) {
        StartPanel startingPanel = new StartPanel();
        startingPanel.makeStartPanel();
        StartEvents starter = new StartEvents(startingPanel);
        starter.rulesButton();
        starter.exitButton();
        starter.highScoresButton();
        ArrayList<Integer> dimensions = starter.boardSizeSelector();
        
        // Problem Zone
        System.out.println(StartEvents.scoreOption);
        starter.scoringSystem();
        System.out.println(StartEvents.scoreOption);
        // The two values of scoreOption should be different
        
        String[] playPanelDetails = {"970", "Player 1", "450"};
        
        // Final Start of the Game
        starter.startGameButton(playPanelDetails, dimensions);
        
    }

}

Furthermore, could you please let me know regarding the following questions:

1. Implementing "ActionListener" within another "ActionListener" is recommended? Good Practice?
2. Can there only be one declaration of the "actionPerformed" method or can it be overloaded too?
3. Is it possible to get a return value from "actionPerformed" method?

I would be really grateful if even some hints could be provided. I really tried a lot and only then posting it here. Thank you very much in advance.

Small Edit: When I "System.out.println" the "actioncommand" there itself, it does work perfectly, printing in the console. But not when I try to update the class variable and then try to print it after the method call. Dunno if this helps.
