i have an array list that is holding two string arrays.. one dedicated to usernames and another to passwords

    ArrayList<Person> popul = new ArrayList<Person>();
    String[] u = {"Herp","Derp","LOL"};
    String[] p = {"hello123", "qwerty42", "iliketurtles"};

in another class inside the main method i am trying to get the passwords from the popul arrayList to turn into hash.. i have set up a loop to get each password but I do not know how to get only from the password string array and not the username...

for(int x = 0; x < popul.size(); x++){
  popul.get(x);
}

any help is greatly appreciated, thanks

I do not see the connection between popul, people, u and p. Please clarify. – Alp Jun 18 '11 at 22:51
    
please provide a more clear code sample of what you are doing. I do not see how you are using the arrays u or p and there is no declaration of people at all. – Bueller Jun 18 '11 at 22:56
    
sorry, completely screwed up writing the code, mixed some things up.. apologize for the lack of attention – Mike Jun 18 '11 at 23:02

Confusing code, I am assuming you have an arraylist holding 2 String arrays u and p and you want to traverse the passwords array. If that is correct, and if u added u first and p later, your password array can be retrieved by

popul.get(1);

So to traverse the passwords you should be doing

for(String password: popul.get(1))
{
 System.out.println(password);
}
