Question

Basically I need help creating a method that will save the following variables to a .txt file using a linked list data structure.

Name - Text Field
Age - Text Field
Gender - Drop down Combobox
Email - Text Field
Username - Text Field
Password - Password Field

These items are on a GUI that I already created, I am not going to paste the code in here because there's too much. However once the user enters the data into text fields or chooses from a drop down combobox they click a button that will initialize the method to save all of this to a text file.

Explanation / Answer

import java.util.LinkedList;
import java.io.*;

public class LinkedAccountList {

          public LinkedAccountList() {
                writeToFile(createList());

          }

          public void writeToFile(LinkedList acct) {

               String file_name = "output.txt";
               File file = new File(file_name);
               try {
                            boolean exist = file.createNewFile();
                            if (!exist) {
                                System.out.println("File already exists.");
                                System.exit(0);
                            } else {
                                FileWriter fstream = new FileWriter(file_name);
                                BufferedWriter out = new BufferedWriter(fstream);

                                for (Account element : acct) {
                                     out.write(element.name + " " + element.age + " "
                                                 + element.email + " " + element.gender + " "
                                                 + element.username + " " + element.password + " ");
                                }
                                out.close();
                                System.out.println("File created successfully.");
                            }
                 } catch (Exception e) {

                 }

          }

          public LinkedList createList() {

                 LinkedList ml = new LinkedList();

                 ml.add(new Account("Gary", "21", "Male", "gary@aol.com", "gary12","gary123"));
                 ml.add(new Account("Sally", "21", "Female", "sally@aol.com", "sally12","sally123"));

                 for (Account element : ml) {
                     System.out.println(element + " ");
                  }

                  return ml;
          }

          private class Account {
                    private String name;
                    private String age;
                    private String gender;
                    private String email;
                    private String username;
                    private String password;

                    Account(String n, String a, String g, String e, String u, String p) {
                                   name = n;
                                   age = a;
                                   gender = g;
                                   email = e;
                                   username = u;
                                  password = p;
                    }

                    public String toString() {
                                return name + " " + age + " " + gender + " " + email + " "+ username;
                    }
            }

            public static void main(String args[]) {

                      LinkedAccountList p = new LinkedAccountList();
             }

}
