PrintWriter - print methods

Question

Hi I am trying to print an address book to a file and am
having some trouble. I'm not familiar with writing
objects to a file. Any suggestions?
Here is my abbreviated code:
// type of address book
OrderedLinkedList<ExtPerson> addBook
                 = new OrderedLinkedList<ExtPerson>();
// read in file of addresses
        Scanner inFile = new Scanner(new FileReader("c:\\addressList.txt"));
// to write the file to the c drive
        PrintWriter outFile = new PrintWriter("c:\\addressBook.txt");
     // menu driven search program
   Boolean token1 = false;
   while(!token1) {
   System.out.println();
   System.out.println("To add a new entry to the address book, enter 1.\n"
            + "To print the address book, enter 2.\n"
            + "To delete an entry from the address book, enter 3.\n" +
            "To exit, enter 0.\n");
    int token2 = console.nextInt();
    switch (token2) {
        case 0: // to exit
            token1 = true;
            outFile.println(addBook);
            outFile.close();
            break;

What are you using to view the file? If it's Notepad on Windows, then you'll probably be seeing little squares where the newline is supposed to be. This is because Notepad doesn't recognize "\n" as a newline, it only works for "\r\n".
Try viewing the file in some other editor (I personally use [Notepad++|http://notepad-plus.sourceforge.net/uk/site.htm], and incidentally, it's the first result when you Google for notepad), maybe Wordpad or Word. You should see the correct output.
You can also try using System.line.separator to get the system specific line separator. But keep in mind that this will potentially give you different files on different OSs - you'll get the same output you're getting right now on a *nix system and so you'll have the same problem. I'd recommend just ignoring Notepad and continue using "\n"
