Bank ATM with Classes

Instructions

For this exercise you will be creating a BankAccount class.

It will have the following properties...

• type (e.g., "checking"), which should be determined by some input
• money, which should start out as 0

It should have the following methods...

• withdraw, which should decrease the amount of money by some input
• deposit, which should increase the amount of money by some input
• showBalance, which should print the amount of money in the bank to the console.

The BankAccount class has a transactionHistory property which keeps track of the withdrawals and deposits made to the account.

• Make sure to indicate whether the transaction increased or decreased the amount of money in the bank.

Bonus

Give the BankAccount class a backupAccount property that can, optionally, contain a reference to another instance of the class, determined by some input

• Whenever a BankAccount's balance goes below zero, it will remove money from the instance stored in backupAccount so that its balance goes back to zero.
• This should trigger a withdrawal in the back up account equal to the amount of money that was withdrawn from the original account.
