Returning Array Data

Question

Hello. I am trying to create an array of bank accounts and only return one of those accounts based on input from a scanner i.e entering a pin number. I know how to create the scanner and create the objects I just can not figure out for the life of me how to search the array based on the pin number and return only the object containg the information I want. The code i have so far is. I am very new to Java so I am still learning a lot any help would be appreciate.
import java.util.Scanner;
public class User
     private String accountNumber;
     private String firstName;
     private String lastName;
     private String memberType;
     private String pin;
Public User(String a, String f, String l, String m)
          accountNumber = a;
          firstName = f;
          lastName = l;
          memberType = m;
     public void print()
          System.out.printf("Your Account Number is: %s\nYour Name is: %s %s\nYour Member Type is: %s\n"
                    , accountNumber, firstName, lastName, memberType );
          System.out.println();
     public void getPin()
          Scanner input = new Scanner( System.in );
          System.out.print("Please input Account Number: ");
          pin = input.nextLine();
public class UserTest
     public static void main(String [] args)
          User[] account = new User [5];
          account[0] = new User ("1000","Pat", "Roberts", "Premier");
          account[1] = new User ("2000", "Andy", "Garcia", "Regular");
          account[2] = new User ("3000", "Debby", "Dupont", "Regular");
          account[3] = new User ("4000", "Ramon", "Spaulding","Regular");
          account[4] = new User ("5000", "Becky", "Dunow", "Regular");
     for (int i = 0; i<= account.length; i++)
account.print();     

Answer 1

Actually all that loop does is print out the details of all the accountsActually, it doesn't even do that, he is missing a in there. ;-)
It also looks like you arn't setting a pin for a user anywhere, so how will you be able to compare the entered pin with a stored one.
I think you getPin() method, should be in your main class, or even just part of your main method.
There is also a serious flaw in the whole concept, because it means that no to users can have the same PIN. A user should be identified by his/her account number and PIN
Actually, looking at your code again, perhaps thats what you are trying to do?
Anyway, this is what I would be doing:
public class User
     private String accountNumber;
     private String firstName;
     private String lastName;
     private String memberType;
     private String pin;
     public User(String a, String f, String l, String m, String p)
          accountNumber = a;
          firstName = f;
          lastName = l;
          memberType = m;
          pin = p;
     public void print()
          System.out.printf("Your Account Number is: %s\nYour Name is: %s %s\nYour Member Type is: %s\n"
                    , accountNumber, firstName, lastName, memberType );
          System.out.println();
     public String getAccountNumber() {
          return accountNumber;
     public String getFirstName() {
          return firstName;
     public String getLastName() {
          return lastName;
     public String getMemberType() {
          return memberType;
     public String getPin() {
          return pin;
import java.util.Scanner;
public class UserTest
     public static void main(String [] args)
          User[] account = new User [5];
          account[0] = new User ("1000","Pat", "Roberts", "Premier", "1234");
          account[1] = new User ("2000", "Andy", "Garcia", "Regular", "1234");
          account[2] = new User ("3000", "Debby", "Dupont", "Regular", "1234");
          account[3] = new User ("4000", "Ramon", "Spaulding","Regular", "1234");
          account[4] = new User ("5000", "Becky", "Dunow", "Regular", "1234");
          System.out.print("Enter your account number:");
          Scanner scanner = new Scanner(System.in);
          String accountNumber = scanner.nextLine();
          for (int i = 0; i < account.length; i++)
               if (accountNumber.equals(account.getAccountNumber())) account[i].print();
