Write a bank account program that handles account balances for an array of bank accounts. There are two types of accounts: Checking and Savings. Each of these accounts should allow for deposits, withdrawals, and the display of account balances. Balances should be displayed by printing the type of account (checking or savings) and then the balance. For the checking account, you should also be able to write a check - but the bank will take a dollar for every check it processes as a service fee. Additionally, the savings account should be able to compound interest by multiplying its interest rate by the balance and adding that to the current balance. Provide appropriate constructors and additional methods as necessary. Study the given main method and output for details. Write a driver class to test your code. The driver class should contain the main method below. Replace the comment with code that creates the exact same test cases but uses a Java ArrayList instead of an old-fashioned array to store the three instances. Also, improve upon the code that runs through the test cases (in the ArrayList) to display them. Leave the existing code (below) that deals with the array, as-is. public static void main(String[] args) { BankAccount[] accounts = new BankAccount[3]; accounts[0] = new Savings(1100, .05); accounts[0].deposit(100); accounts[0].withdraw(200); ((Savings) accounts[0]).addInterest(); accounts[1] = new Checking(100); accounts[1].deposit(50); accounts[2] = new Checking(200); accounts[2].withdraw(100); accounts[2].deposit(75); ((Checking) accounts[2]).writeACheck(50); for(int i = 0; i < accounts.length && accounts[i] != null; i++) { accounts[i].display(); } System.out.println(ArrayList Results:); // INSERT ARRAYLIST CODE HERE } Expected Output: Savings account balance = $1050.00 Checking account balance = $150.00 Checking account balance = $124.00 ArrayList Results: Savings account balance = $1050.00 Checking account balance = $150.00 Checking account balance = $124.00
