Write a program for a bank that lets them create objects representing customer savings accounts and checking accounts. Your program should have the following three classes:




  • Account, with the following data:


    • A field named 'balance' which contains how much is in the account.

    • A constructor which allows the client to initialize 'balance'

    • Override toString to print how much is currently in the account.

    • A 'deposit' method which adds money to 'balance' and a'withdraw' method which removes money from 'balance'.

    • An ArrayList named 'transactions' that holds strings. Give it 'protected' access. When a transaction (withdrawal or deposit) occurs, add a string to 'transactions' describing the transaction. i.e.: "$100 withdrawn from the account"

    • A 'displayTransactions' method which prints out each string in 'transactions'.




  • SavingsAccount, which extends Account, with the following data.

    • A 'calculateInterest' method which increases the 'balance' by 2%. It also adds a string to the inherited 'transactions' ArrayList. i.e. "$30 in interest added to the account".

    • Override 'withdraw':

      • If the amount the client wants to withdraw would bring 'balance' below $200, charge a $10 fee and do not perform the withdrawal.

      • Otherwise, pass the withdrawal amount to the superclass version of the 'withdraw'.






  • CheckingAccount, which extends Account, with the following data.

    • A 'numBounced' field to track how many checks have bounced. This field should have a getter.

    • A 'processCheck' method to simulate a customer's check being cashed, with two parameters: an amount and who the check was written to.

      • If the check would bring 'balance' below 0, increment 'numBounced' and charge a $25 fee (note: The fee might bring balance below 0, which is okay).

      • Otherwise, subtract the amount from 'balance' and add a string to the inherited 'transactions' ArrayList. i.e. "$50 check cashed by Target".







  • On Main.java, in the main method, create a CheckingAccount and SavingsAccount object. Test the methods you wrote!Note: You do not need user input, you can simply hard-code the values.
