Bank Management - Part 4

Interface: a contract of behavior.

A class that implements an interface must override all of its methods.

Task 1

Based on the requirements, Chequing implements a Taxable interface. Add a void tax(double income) method inside Taxable and override it inside Chequing.

Task 2

Create a unit test named incomeTax().

• deposit $4,000 into the chequing account.
• call tax() for an income of $4,000.
• assert the resulting balance is 5374.51.

You can find the taxable income and tax rate inside requirements.txt.

Good Luck!
