Follow Up to Scanner Input from File

Question

Alright, I have another problem. My code is this:
for (int j = 0; j < username.length; j++) {
     String line = input.nextLine();          // Create a temporary String that will store each line
     // Check if the temporary line isn't empty
     if (line.length() > 1) {
             numAccounts++;
             username[j] = line.substring(10);
             password[j] = input.nextLine().substring(10);
             System.out.println(username[j]);
     } else {     // If the temporary line is empty, go back on the loop to prevent empty array entries
              j--; }
     }It runs through once, and then stops. Here are the declarations:
static int numAccounts = 1;
static String[] username = new String[numAccounts];
static String[] password = new String[numAccounts];
static  Scanner input = new Scanner(new BufferedReader(new FileReader("account.txt")));Which was done outside of the main method.
Why does the loop iterate only once?

Woah, don't need to get all heated up about something I'm doing wrong. I'm just trying to figure this out. Sorry if I'm getting on your nerves.
So anyways, I did the ArrayList method with your suggestion of making it an ArrayList of Objects. This is what I have so far:
// Declare the ArrayList that will store all the Account Objects retrieved from the database
static ArrayList<Account> accounts = new ArrayList<Account>();
while (input.hasNextLine()) {
    String line = input.nextLine();          // Create a temporary String that will store each line
    // Check if the temporary line isn't empty
    if (line.length() > 0) {
         //System.out.println(line);
         String currentName = line.substring(10);
         String currentPass = input.nextLine().substring(10);
         Account current = new Account(currentName, currentPass);
         accounts.add(current);
}Yes, I stuck with using the line.length() > 0, because trying to use line != null doesn't work properly for me. Not entirely sure why. Just throws IndexOutOfBoundsException when it's called.
And my Account Object class is as so:
class Account {
     static String username, password;
     Account(String username, String password) {
          this.username = username;
          this.password = password; }
}I tried to print out the username and passwords to the indexes of 0, 1, and 2, and they're all the same.
System.out.println(accounts.get(0).username);
System.out.println(accounts.get(0).password);
System.out.println(accounts.get(1).username);
System.out.println(accounts.get(1).password);
System.out.println(accounts.get(2).username);
System.out.println(accounts.get(2).password);What is also interesting, is that it only fetched (or copied) the last two lines in the text document. It ignores all the entries before that.
Do you know what I did wrong? I think I did a logic error in there somewhere.
