In this problem, you will write a tester class PolymorphismRunner. You are provided with three classes: BankAccount, SavingsAccount and CheckingAccount

Add the code described below to the main method

Create an array of BankAccounts that can hold 5 objects. You will fill the array with the objects specified in the table

Loop through the array

• Deposit $200 in each account
• Withdraw $100 from each account
• Call each account's endOfMonth method and then print the word Balance: and a space, followed by the balance in the account to 2 decimal places
• If the account is an instance of SavingsAccount, cast it to a SavingsAccount and print the word Interest: and a space followed by the interest rate

Your output should look like this

Balance: 1090.00
Balance: 1100.01
Interest: 0.01
Balance: 3094.00
Balance: 1100.01
Interest: 0.01
