    Default How to access an ArrayList of another class?

    public class MemberAccoutList{

    private ArrayList<MemberAccount> membrAcc = new ArrayList<MemberAccount>();

    public ArrayList<MemberAccount> getMembrAcc()
    {
    return membrAcc;
    }
    }

    public class MemeberAccount{

    private int mobileNumber;
    private String password;




    //Create a MemberAccount constructor
    public MemberAccount(int mobNum, String pswd)
    {
    this.mobileNumber = mobNum;
    this.password = pswd;


    }

    public void setMobileNumber(int mobileNumber)
    {
    this.mobileNumber = mobileNumber;
    }


    public int getMobileNumber()
    {
    return mobileNumber;
    }

    }

    public class Validation{

    public boolean joinValidation(String num,String pass, String pass2){

    int number = Integer.parseInt(num);

    for(MemberAccount memb : ma.getMembrAcc())// why this isn't working??? it gives me null
    {

    if(memb.getMobileNumber() == number)
    {
    JOptionPane.showMessageDialog(null, "The mobile number already exist","Error",JOptionPane.ERROR_MESSAGE);
    return false;

    }

    }

    }
    }

    }

    I should point out that ArrayList has a get(int index) method that returns the item at that index. You don't really need to use an iterator with the ArrayList class.
