MCS-024 Assignment July 2012 Q7 b Answer

Question7(b): Consider a class that stores a Bank account holder's name, account number, ATM card number, account balance and ATM PIN. Write a program to store the data onto a disk file, except for the account balance and ATM PIN. Use serialization and transient variables.
Answer:

import java.io.*;
import java.util.*;
public class UserAccount implements Serializable
{
 private transient int atmPin_no;
 private String atmCard_no;
 private String account_number;
 private transient float balance_amount;
 UserAccount(int pin, String cardno, String acc_no, float balance) //constructor
 {
  atmPin_no=pin;
  atmCard_no=cardno;
  account_number=acc_no;
  balance_amount=balance;
 }
  public String toString()
  {
   String pin=(atmPin_no==null)?"(n/a)":atmPin_no;
   Return "Logon info:\n "+" Account  No :"+account_number+"\n Balance:"balance_amount;
  }
   public static void main(String[] args)
   Throws IOException, ClassNotFound Exception
   {
     UserAccount acc=new
     UserAccount(1234,"A983423115","23456789076543",5000.34);
     System.out.println("Login is="+acc);
     ObjectOutputStream obj=new ObjectOutputStream(new FileInputStream("Login.out"));
     Acc=(UserAccount)in.readObject();
     System.out.println("login="+acc);
   }
}
