Constructor

instance Variables

Methods

public static int getParentCode()
public int getAccountNumber()
public void deposit(double amount)
public double getCurrentBalance()
public abstract boolean withdraw(double amount)
public boolean equals(Account other) // are the unique account numbers equals ?
public String toString()
public int comparesTo(Account other) { return this.accountNumber- other.accountNumber } (Note that this method has an ‘s‘ )
public void addOwner(Person p) //adds P to the ArrayList of owners
public ArrayList<Person> getOwners() // returns the ArrayList of owners
public Person remove( Person p) // this emulates the ArrayList’s remove() method (link) . Remember that that method removes the object and then returns the removed object. In this case, you should remove Person P from the ArrayList of owners

CheckingAccount extends Account
This class has to do certain things. You can decide the best way to do it. This class should have a way to
- attempt to withdraw money by writing a check
- public void writeCheck(double amount)
- public void cancelCheck(int checkNumber)
  - be able to cancel checks and keep track of the check numbers that have been cancelled
  - when a check is cancelled the amount associated with that check is returned back to the balance
One solution
- every time you write a check, you need a new check “#” (static variable like an id)
- writeCheck( double amount) - > tries to call this.withdraw(double amount) as long as the balance is enough and records a new check number by adding it to an ArrayList<Integer> that stores the check numbers of cancelled checks. It would also need a parallel ArrayList<Double> to store balances (in case the check is cancelled and the amount is refunded to the balance)

SavingsAccount extends Account

instance variables
- private double interestRate
- private ArrayList<Double> dailyBalances
static variables
- public static final int MINIMUM_BALANCE=100; // this is the absolute minimum amount of money that must always be in the account
methods
- public boolean withdraw(double amount) //@override the withdraw() method to ensure that currentBalance the never gets below MINIMUM_BALANCE
- public void recordDailyBalance() // @ record current day’s balance by storing current balance.
- public double projectBalance(double timeInYears) // use the compound interest formula . Assume that the bank compounds the balance monthly. To learn more about how compound interest really works, click here .
- public void updateInterestPayment() // @ once a month update account based on average daily balances and interest rate

instance Variables

Methods

public boolean withdraw(double amount , boolean isEarly ) //@override the withdraw() and applies penalty to balance

When you are done, you can begin the Bank project .
