Bank Class

You have a lot of flexibility in creating this class, but here is what it should be able to do

• manage an array list of Accounts that could be any kind of account  private ArrayList<Account>  

Functionality that you *must* implement.

It’s up to you to decide how to implement the functionality below. You will only lose credit if your methods clearly make no sense, have bad variable names/method names.

• add an Account  (of any type)
• remove an account by
  • account id
  • owner (a Person object)

The functionality above ^^ can be implemented in any efficient way that makes sense, but it must be implemented. I am leaving that part up to you!

• Some Specific Required Methods
  • public ArrayList<Person>  topAccountOwners(double cutoff)
    • this method returns an ArrayList of the owners whose accounts have at least cutoff  amount of balance
  • public void nightlyUpdate()
    • this runs through the accounts and if account is a SavingsAccount , then it calls that object’s recordDailyBalance()  method (You are going to have to use instanceOf  and then cast those  accounts to a  SavingsAccount )
  • public  Account topBalance()   ; returns the Account  object with the greatest balance
  • public  Account[] allWithinRange(double min, double max) returns an array of Accounts whose balances range from min  to max , inclusive
  • public  boolean transfer( double amount, int accountIdFrom , int accountIdTo) ;  this method transfers  money from the one account to the other. If the accountIdFrom  does not have enough $$, this method returns false.
  • public  void monthlyUpdate()
    • this runs through the accounts and if
    • account is a SavingsAccount , then it calls that object’s updateInterestPayment() method
  • ** extra credit ArrayList<Account> sortByAmount()  
    •   this method returns an arraylist of Accounts sorted by amount in the account
