Create a * .csv file with data found from a file

I'm developing a project that extracts information from a * .pdf file, I was saving this information in a * .txt file, but now I was asked to save this information in the form of a worksheet, I want to create a * file. csv, but the only way I found to create the file would be to determine what would be written in each column, but I need to put the value of the variables in those columns.

public class modelo {

public static void main(String[] args) {
    System.out.println("inicio");
    Timer timer = null;
    if (timer == null) {
        timer = new Timer();
        TimerTask tarefa = new TimerTask() {
            public void run() {
                try {

                    File diretorio = new File("C//teste//");
                    File[] arquivos = diretorio.listFiles();

                            if (arquivos[x].getName().endsWith("pdf")) {

                                File f = arquivos[x];
