Question

I will try to keep this as simple as possible. Basically I have a Linked List of data where every element is on a separate line. However when I try to save it to a file it all just gets linked together in one long String. I need it to save to the file on different lines because I have to keep reading and saving to this file multiple times, and the way I read the file everything has to be on separate lines.
Thanks!

Code for Saving Linked List to file:

        String file_name = "output.txt";
        try {

                FileWriter fstream = new FileWriter(file_name);
                BufferedWriter out = new BufferedWriter(fstream);

                ListIterator itr = account.listIterator();
                while (itr.hasNext()) {
                    Account element = (Account) itr.next();
                    out.write(element + "\n");
                }

                out.close();
                System.out.println("File created successfully.");

        } catch (Exception e) {
        }

Code for creating Linked List:

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.LinkedList;
public class Main extends javax.swing.JFrame implements ActionListener{

public static String readLine(BufferedReader br) throws IOException {
    String rl = br.readLine();
    if (rl.trim().length() > 2){
        return rl;
    }else return readLine(br);
}

public static void main(String[] args) {

    LinkedList<Account> account = new LinkedList<Account>();

    try
    {
        read(account, "output.txt");
    } catch (Exception e)
    {
        System.err.println(e.toString());
    }
        display(account);
    }

    public static void read(LinkedList<Account> account, String inputFileName) throws java.io.IOException
    {
        BufferedReader infile = new BufferedReader(new FileReader(inputFileName));
        while(infile.ready())
        {

            String username = readLine(infile);
            String password = readLine(infile);
            String email = readLine(infile);
            String name = readLine(infile);
            String breed = readLine(infile);
            String gender = readLine(infile);
            String age = readLine(infile);
            String state = readLine(infile);
            String hobby = readLine(infile);

            Account a = new Account(username, password, email, name, breed, gender, age, state, hobby);
            account.add(a);
            a.showList();
        }
        infile.close();
    }

    public static void display(LinkedList<?> c)
    {
        for (Object e : c)
        {
            System.out.println(e);
        }
    }

Answer 1

Instead,

out.write(element + "\n");

try

out.write(element);
out.newLine();

Referring to the javadoc of newLine() method:

Write a line separator. The line separator string is defined by the
system property line.separator, and is not necessarily a single
newline (‘\n’) character.

So, \n does not seem correct always for new line.
