toString method in vector.

[Kelly Frasure]

I would like to add a toString method to print out all of the elements in the vector. The code will not compile. This is my code. I don't understand why I'm getting this error. The problem is in the AccountList program.

import java.text.NumberFormat;
public class Account
{
  private NumberFormat fmt = NumberFormat.getCurrencyInstance();
  private final double RATE = 0.03;
  private String name, phone;
  private double balance;
  private int acctNumber;
  public Account (int id, String client, String number,
                  double funds)
  {
    acctNumber = id;
    name = client;
    phone = number;
    balance = funds;
  }
  public boolean equals(Object other)
  {
  return name.equals(((Account)other).name);
  }
  public double deposit (double amount)
  {
if (amount < 0)
{
  System.out.println ();
  System.out.println ("Error: Deposit amount                is invalid.");
  System.out.println (acctNumber + " " + fmt.format     (amount));
    }
    else
      balance = balance + amount;
    return balance;
  }
  //-------------------------------------------------------------
  //Withdrawal
  //-------------------------------------------------------------
  public double withdraw (double amount)
  {
 if (amount < 0)
 {
   System.out.println ();
   System.out.println ("Error: Withdraw amount is invalid.");
   System.out.println ("Account: " + acctNumber);
   System.out.println ("Requested: " + fmt.format(amount));
     }
     else
       if (amount > balance)
       {
      System.out.println ();
      System.out.println ("Error: Insufficient funds.");
      System.out.println ("Account: " + acctNumber);
      System.out.println ("Requested: " + fmt.format(amount));
      System.out.println ("Available: " + fmt.format(balance));
       }
       else
         balance = balance - amount;
     return balance;
  }

  {
     balance += (balance * RATE);
     return balance;
  }

Hi, Kelly.
The problem is, AcctRoster only has scope within the constructor.
Make this Vector an instance variable instead, and try it again.
Good luck,
Art
