真实的更新语言- Java

我正在用java创建一个桌面程序,在这个程序中有一个JOptionPane来选择用户想要使用的语言,但是当用户选择其中一个选项时,我的组件的文本不会真实的更新。
我使用.properties文件作为语言 例如,语言选项中提供:
en.properties

selectOptions=Select one of the options below:
startButton=START
optionsButton=SETTINGS

jp.properties

selectOptions=以下のオプションから選択してください:
startButton=スタート
optionsButton=設定

在我的LanguageManager类中,我配置了我的密钥的get,我有updateLanguage方法,但是当我使用updateLanguage方法时,它改变了我的语言,但文本没有改变。

public void updateLanguage(String selectedLang, String selectedLocale) {
        lang = selectedLang;
        locale = selectedLocale;
        setLanguage(lang, locale);
    }

根据我的研究,执行更新的最常见方法是创建一个方法来更新我的组件的文本,但由于我有几个组件,我必须向我的方法传递几个参数,它类似于下面的示例:

public void updateTexts(JButton button1, JButton button2, JLabel label1, JLabel label2){
      button1.setText(languagerManager.getButton1("button1"))
      button2.setText(languagerManager.getButton2("button2"))
      label1.setText(languagerManager.getButton1("label1"))
      label2.setText(languagerManager.getButton1("label2"))
}

但我认为这样做效率不高。
下面是我的类以及我在选择另一种语言时如何尝试实现此更新。
主屏幕类别:

private LanguageManager languageManager;

 public MainScreen() {

   languageManager = LanguageManager.getInstance();

   startButton   = new JButton(languageManager.getStartButton());
   rankingButton = new JButton(languageManager.getRankingButton());
   optionsButton = new JButton(languageManager.getOptionsButton());
   exitButton    = new JButton(languageManager.getExitButton());

   optionsButton.addActionListener(e -> Buttons.optionsButton(e));
}

我打开类的语言设置:

public class Buttons {

   static public void optionsButton(ActionEvent e) {

        LanguageManager languageManager = new LanguageManager();

        String[] languages = {"Português", "English", "Español", "日本"};

        JComboBox<String> comboBox = new JComboBox<>(languages);

        JPanel panel = new JPanel();
        panel.add(comboBox);

        int result = JOptionPane.showConfirmDialog(null, panel, "Selecione uma linguagem", JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);

        if(result == JOptionPane.OK_OPTION){

            String selectedLang = "";
            String selectedLocale = "";

            switch(comboBox.getSelectedIndex()) {
                case 0: // Português
                    selectedLang = "pt";
                    selectedLocale = "pt_BR";
                    break;
                case 1: // English
                    selectedLang = "en";
                    selectedLocale = "en";
                    break;
                case 2: // Español
                    selectedLang = "es";
                    selectedLocale = "es";
                    break;
                case 3: // 日本
                    selectedLang = "jp";
                    selectedLocale = "jp";
                    break;
            } 

            languageManager.updateLanguage(selectedLang, selectedLocale);

        }

    }

}

负责语言的类:

public class LanguageManager {  

    private static LanguageManager instance;

    private ResourceBundle messages;

    private String lang, locale;
    
    public LanguageManager() {

        }
        return instance;
    }

    public void updateLanguage(String selectedLang, String selectedLocale) {
        lang = selectedLang;
        locale = selectedLocale;
        setLanguage(lang, locale);
    }

    public void setLanguage(String messageFile, String languageCode) {
        messages = ResourceBundle.getBundle("ApsProject.src.Languages." + messageFile, new Locale(languageCode));
    }

    public String getTitleAps() {
        return messages.getString("titleAps");
    }
    
    public String getSelectOptions() {
        return messages.getString("selectOptions");
    }

        return messages.getString("numberOfParticipants");
    }

    public String getNameOfParticipantes() {
        return messages.getString("nameOfParticipantes");
    }
    
    public String getStartButton() {
        return messages.getString("startButton");
    }

    public String getMatchButton() {
        return messages.getString("matchButton");
    }

    public String getOptionsButton() {

    }

    public String getPlayer5() {

    }

    public String getTeam2() {
        return messages.getString("team2");
    }

    public String getTeam3() {
        return messages.getString("team3");
    }

    public String getTeam4() {
        return messages.getString("team4");
    }

    public String getTeam5() {
        return messages.getString("team5");
    }

        return messages.getString("lap1Player1");
    }
    
    public String getLap1Player2() {
        return messages.getString("lap1Player2");
    }

    }

    public String getLap1Player4() {
        return messages.getString("lap1Player4");
    }

    public String getLap1Player5() {
        return messages.getString("lap1Player5");

    }

    public String getLap2Player3() {
        return messages.getString("lap2Player3");
    }

    }

    public String getTotalTimeP1() {
        return messages.getString("totalTimeP1");
    }

    public String getTotalTimeP2() {

    }

    public String getTotalTimeP4() {
        return messages.getString("totalTimeP4");
    }

    public String getTotalTimeP5() {
        return messages.getString("totalTimeP5");
    }

    public String getPlayer() {
        return messages.getString("Player");
    }

}

如果有人知道我能做什么,我会很感激。

经过几次尝试,我得到了它.这里是更新的代码:

Class `Language Manager`: 

    public class LanguageManager {  

    private static LanguageManager instance;

    private ResourceBundle messages;

    private String lang, locale;
    
    public LanguageManager() {

        setLanguage("en","en");

    }

    public static LanguageManager getInstance() {
        if (instance == null) {
            instance = new LanguageManager();
        }
        return instance;
    }

    public void updateLanguage(String selectedLang, String selectedLocale) {

        lang = selectedLang;
        locale = selectedLocale;
        setLanguage(lang, locale);
    }

    public void setLanguage(String messageFile, String languageCode) {
        messages = ResourceBundle.getBundle("ApsProject.src.Languages." + messageFile, new Locale(languageCode));
    }

    public String getString(String key) {
        return messages.getString(key);
    }
}

Buttons类:

static public void optionsButton(ActionEvent e, JButton sB, JButton rB, JButton oB, JButton eB) {

        LanguageManager languageManager = LanguageManager.getInstance();

        String[] languages = {"日本", "English", "Español", "Português"};

        JComboBox<String> comboBox = new JComboBox<>(languages);

        JPanel panel = new JPanel();
        panel.add(comboBox);

        String okText = languageManager.getString("langOptionOk");
        String cancelText = languageManager.getString("langOptionCancel");

        UIManager.put("OptionPane.okButtonText", okText);
        UIManager.put("OptionPane.cancelButtonText", cancelText);

        int result = JOptionPane.showConfirmDialog(null, panel, languageManager.getString("languageOption"), JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);
        
        if(result == JOptionPane.OK_OPTION){

            String selectedLang = "en";
            String selectedLocale = "en";

            switch(comboBox.getSelectedIndex()) {
                case 0: // 日本
                    selectedLang = "jp";
                    selectedLocale = "jp";
                    break;
                case 1: // English
                    selectedLang = "en";
                    selectedLocale = "en";
                    break;
                case 2: // Español
                    selectedLang = "es";
                    selectedLocale = "es";
                    break;
                case 3: // Português
                    selectedLang = "br";
                    selectedLocale = "pt_BR";
                    break;
            } 
            
            languageManager.updateLanguage(selectedLang, selectedLocale);;
            sB.setText(languageManager.getString("startButton"));
            rB.setText(languageManager.getString("rankingButton"));
            oB.setText(languageManager.getString("optionsButton"));
            eB.setText(languageManager.getString("exitButton"));
        }

    }

如何调用optionsButton方法,以及如何定义MainScreen中的文本:

languageManager = LanguageManager.getInstance();
        startButton   = new JButton(languageManager.getString("startButton"));
        rankingButton = new JButton(languageManager.getString("rankingButton"));
        optionsButton = new JButton(languageManager.getString("optionsButton"));
        exitButton    = new JButton(languageManager.getString("exitButton"));
        optionsButton.addActionListener(e -> Buttons.optionsButton(e, startButton, rankingButton, optionsButton, exitButton));

在我的updateLanguage方法中,我更新了语言,我的新屏幕将已经使用所选语言创建,我必须做的是更新我的MainScreen的语言,因为它已经打开并加载了字符串
