Vector login = new Vector ();
login.add (username);
login.add (password);

//...
username = v.get (0);
password = v.get (1);
----
if this is your question.

If you need more than one password, consider of modelling this another way:
public class Login
{
private String username;
private String password;

public Login (String u, String p)
{
username = u;
password = p;
}
// getUsername meth. etc. ...
}

Vector logins = new Vector ();
logins.add (new Login ("Frank", "Zappa"

I guess a Map would be more helpful in this case.
I guess more: I misunderstood the question.

hi there this what i actually need to do

A constructor which takes two parameters; the users name (a string) and the users cipher key (a string). A Vigenere cipher matrix is initialised if the key is valid (same rules as the last class) and the users name is valid. The users name is invalid if the string contains a space. Everything else is valid (upper and lower case letters, symbols, ... ).
An accessor called "getUser" to return the users name.
A main method that tests the functionality of "User"
