[FIXED] How can have reflect.field library the value of a Field?

Issue

I am doing an application, and I need to create 10 TextFields and save value in a XML file that i have. (I know how to save it in XML)

The issue I have is I want to save it all (in a XML) automatically without repeating the code like 10 times for each variable.

I am trying reflect.Field library to do it (Not accomplished) but i don't know if it's the best solution.

    public TextField Tf_TestI1;
    public TextField Tf_TestF1;
    public TextField Tf_TestI2;
    public TextField Tf_TestF2;
    public TextField Tf_TestI3;
    public TextField Tf_TestF3;
    public TextField Tf_TestI4;
    public TextField Tf_TestF4;
    public TextField Tf_TestI5;
    public TextField Tf_TestF5;
//Pair them and save it in XML
private void stuffVariables(){
        String nameField1=  "Tf_TestI";
        String nameField2=  "Tf_TestF";
        Field[] fields = Controller.class.getFields();
        for (int i = 0; i <fields.length ; i++) {
            if (fields[i].getName().startsWith(nameField1)){
                for (int j = 0; j < fields.length ; j++) {
                    if (fields[j].getName().equals(nameField2+fields[i].getName().substring(fields[i].getName().length()-1))){
                        System.out.println("EQUALS : "+fields[i].getName() + " = "+ fields[j].getName());
                        try {
                            //System.out.println("1: "+fields[i].getValue);

                        } catch (IllegalAccessException e) {
                            e.printStackTrace();
                        }

                    }
                }
            }
        }

I am trying to get the pair of Test Initial and Final to finally save it in XML like this...

    <TESTS>
          <TEST>
            <INITIAL>AD</INITIAL>
            <FINAL>AVB</FINAL>
          </TEST>
          <TEST>
            <INITIAL>AQEW</INITIAL>
            <FINAL>AVFE</FINAL>
          </TEST>
    <!--   ... MORE TEST -->
    <TESTS>

Solution

My main objective was to make it easy when I add more TextFields... Using HashMap I only have to add a Key to his Value. Using numbers in the Key made it more easy in my case.

 //[...]
 Map<String, TextField> map; //Global variable
 //I just have to add the new TextFields to the HashMap
 private void mapSaveRangs() {
    map = new HashMap<>();
    map.put("rangInitial1", tfrangInitial1);
    map.put("rangFinal1", tfrangFinal1);
    map.put("rangInitial2", tfrangInitial2);
    map.put("rangFinal2", tfrangFinal2);
    map.put("rangInitial3", tfrangInitial3);
    map.put("rangFinal3", tfrangFinal3);
    map.put("rangInitial4", tfrangInitial4);
    map.put("rangFinal4", tfrangFinal4);
    map.put("rangInitial5", tfrangInitial5);
    map.put("rangFinal5", tfrangFinal5);
}

private void rangsInPairsXML(Element peeRangs) {
    String sKeyrInitial = "rangInitial";
    String sValuerInitial;
    String sKeyrFinal = "rangFinal";
    String sValuerFinal;
    //Making sure that we have pair of 2 
    if (map.size() % 2 == 0) {
        //map half size loop
        for (int numRang = 1; numRang <= map.size() / 2; numRang++) {
            sValuerInitial = map.get(sKeyrInitial + numRang).getText();
            sValuerFinal = map.get(sKeyrFinal + numRang).getText();

            //Verifying values and saving it in peeRang (XML Element)
            if (!(sValuerInitial.equals("") || sValuerFinal.equals(""))) {
                Element eRang = new Element("RANG");
                eRang.addContent(new Element("INITIAL").addContent(sValuerInitial));
                eRang.addContent(new Element("FINAL").addContent(sValuerFinal));
                peeRangs.addContent(eRang);
            }
        }
    } else {
        System.out.println("ERROR!!");
        //[...]
    }
}
