2 CSCUMPS 17 December 2020 Do not sign this declaration. 1. The class and state machine diagrams below describe (simplified) Cashisa objects. These are tax-free savings accounts which cap the deposits at 20,000 per tax year. CashisAs have attributes for the current balance, the amount of money deposited during the current tax year, and the annual interest rate (also known as APR). CashisAs offer bank customers an operation to deposit money. CashiSAs offer the bank operations to start a new tax year, and to end the tax year and credit the earned interest to the account.
