Java/Swing 将输入从多个 JTextField 保存到文件中

Question

i'm trying to code a frame that get from the user a bunch of parameters and save them into a csv file and then redirect to a new frame that run a simulation, the problem is used a for loop to generate easily the text fields however i don't know how to write the event listener that retrive the data from all the text fields,here's the code:

       private void ZoneTexte(String texte,JPanel pan) {
       JLabel label=new JLabel();
       label.setText(texte);
       JTextField text = new JTextField(20);
       pan.add(label);
       pan.add(text);
   }
   /**
    * 
    */
   private void SaveParam() {
       String [] param= {"Nom Milieu","ProbaRoche","ProbaHerbe","Qherbe","DistCaractHerbe","FacteurHerbe","RayonLac","ProfondeurMaxLac","SigmaLac"};
       JLabel label=new JLabel();
       label.setText("Définir vos propres paramètres de simulation:");
       EditPanel.add(label);
       for(String s:param) {
           JPanel pan1= new JPanel();
           ZoneTexte(s+" :",pan1);
           EditPanel.add(pan1);
       }
       JButton save=new JButton();
       save.setText("Enregistrer et démarrer la simulation");
       EditPanel.add(save);
       save.addActionListener(new ActionListener(){
        @Override
        public void actionPerformed(ActionEvent e) {
            // TODO Auto-generated method stub


        }
           });
   }
   [The file format that i desire is this][1]

Answer 1

Keep the text fields in a list and iterate it when saving.

 List<JTextField> fieldList = new ArrayList <>() ;

...
    EditPanel.add(pan1)
    fieldList.add(pan1);
}

 save.addActionListener(e -> {
        for (JTextField field : fieldList) {
             file.writeString(field.getText); // however you want to write it 
        } 
 }

Answer 2

IMHO, you need to use a structure like a Map to keep a reference to each TextField. Then in your listener, you will parse your memory structure so that filling your csv.

// Somewhere in your init class
var fieldsMap = new HashMap<String,TextField>();

// In ZoneTexte method
fieldsMap.put(texte,text);      

// In your listener
var value = mapField.get("ProbaRoche").getText();

Perhaps, use a key unique for the field that can be used in different location of your code.
